Trinity

This page examines the doctrine of the Trinity in five steps: first the biblical witness (OT and NT), then the person of Jesus Christ (dependence, prayer, exaltation, mortality), then the Holy Spirit, then the historical emergence of the doctrine — and finally the most common objections together with answers. It thus follows the line of argument that Fausto Sozzini systematically carried out in his writings in the 16th century (especially in the Racovian Catechism and in De Iesu Christo Servatore).

"Hear, O Israel: the LORD our God, the LORD is one."

Deut 6:4 — the Shema Israel

Introduction — the question at issue

In many churches the Trinity is regarded as the heart of the Christian faith. It claims that God consists of three co-eternal, co-equal, consubstantial persons: Father, Son, and Holy Spirit. Yet this doctrine is found nowhere explicitly in the Bible. It was set down only centuries after Jesus, at the councils of Nicaea (325) and Constantinople (381), under political pressure.

Holy Scripture knows only one God — and this one God is the Father. Jesus Christ is consistently described as the man sent by God, as Messiah, as mediator, and as the Lord exalted by God — never as God himself in the strict sense. The Holy Spirit, in turn, is the effective power of God, not a separate person.

This insight was clearly formulated in the 16th and 17th centuries by the Polish Brethren, especially by Fausto Sozzini (1539–1604). In the Racovian Catechism and in his principal work De Iesu Christo Servatore, Sozzini set out that the Trinity is neither logically free of contradictions nor biblically grounded — it is a post-apostolic construct out of Greek philosophy and ecclesiastical power politics.

The present article examines the doctrine step by step: the biblical witness, the person of Jesus Christ, the Holy Spirit, logical consistency, the historical emergence, and the customary objections — and shows why the Socinian answer is not "heresy" but a return to the apostolic confession.

1. The biblical witness: one God — the Father

The whole biblical understanding of God rests on an immovable confession: God is one. This confession is not a marginal note but the load-bearing foundation of the entire Scripture — from Moses to Paul.

1.1 The monotheism of the Old Testament

The Old Testament forms the immovable foundation of the biblical understanding of God. Its witness is unambiguous, uncompromising, and nowhere dissolved into a multiplicity of persons. Israel is not called to a "God in three persons," but to undivided fidelity to the one God Yahweh.

Deut 6:4:
"Hear, O Israel: the LORD our God, the LORD is one."

This verse — the Shema Israel — is the central confession of faith of Israel. It was and is prayed daily to this day. The Hebrew echad here means numerical unity, not a "complex unity": God is one. Sozzini emphasized that, had God wished to reveal a three-person structure, he would not, of all places, have expressed himself in the central confession of his people in the manner of a strict monotheist.

Isa 43:10–11:
"Before me no god was formed, nor shall there be any after me. I, I am the LORD, and besides me there is no savior."

These words categorically exclude every further divine person. God here claims absolute uniqueness — not only over against the idols of the heathen, but over against any conceivable divine entity whatsoever. If God himself says that besides him no god exists, then Jesus too cannot be God in the proper sense.

Isa 44:6:
"I am the first and I am the last, and besides me there is no god."

Here God claims not only uniqueness but also comprehensive sovereignty over beginning and end. If the doctrine of the Trinity were correct, such a self-statement would have to be at least ambiguous or hint at a collective mode of speech. It does not — and that is precisely the argument.

Mal 2:10:
"Have we not all one Father? Has not one God created us?"

Here too the unity of God is emphasized, this time in his relationship to human beings. God is one Father — not one of three. The emphasis lies expressly on "one." The text knows of no hidden threeness behind the unity.

1.2 The monotheism of the New Testament

The New Testament does not stand in contradiction to Old Testament monotheism but confirms and deepens it. Despite all the high christological statements about Jesus, the unity of God remains untouched. On the contrary: it is precisely the central confessional texts of the NT that carefully distinguish between the one God and the Christ sent by him.

John 17:3:
"And this is eternal life, that they know you, the only true God, and Jesus Christ whom you have sent."

This statement of Jesus stands at the center of his farewell prayer. He does not speak here to human beings, but to God himself — and expressly calls the Father the "only true God," while calling himself the one "sent." Were Jesus part of a Trinity, this self-distinction in prayer would simply be unintelligible.

1 Cor 8:4–6:
"Yet for us there is one God, the Father, from whom are all things, and one Lord, Jesus Christ, through whom are all things."

Here Paul summarizes the Christian confession of faith in clear, structured form. He speaks expressly of one God — the Father and, distinct from him, of one Lord — Jesus Christ. This distinction is not accidental: the Father is the origin ("from whom"), Jesus the mediator ("through whom"). A trinitarian reading must subsequently soften this structure — Paul himself does not.

Eph 4:4–6:
"There is one body and one Spirit … one Lord, one faith, one baptism, one God and Father of all, who is over all and through all and in all."

Here too we encounter a structured declaration of unity. Paul speaks of one Spirit, one Lord, and one God — and identifies this one God unmistakably with the Father. Were the Trinity biblical, at least some hint of a three-personal unity would have to appear here.

1 Tim 2:5:
"For there is one God, and there is one mediator between God and men, the man Christ Jesus."

In Socinian theology this verse is regarded as a key text against the doctrine of the Trinity. It joins two central statements: there is only one God, and there is only one mediator between this God and human beings — and this mediator is expressly the man Christ Jesus. Mediation presupposes two distinct parties: God on one side, human beings on the other. Jesus stands as mediator between them — he is not himself God and not merely a human being, but the man who joins God and humanity.

Sozzini saw in this verse one of the clearest rejections of any trinitarian Christology: Jesus is the man, who has placed himself in our mortality in order to bring us to God — he stands between, not on the side of God.

2. Jesus Christ — man, Messiah, mediator

If the doctrine of the Trinity is true, Jesus would have to speak in the Gospels as a consubstantial, co-eternal, equally omniscient God. In fact he does the opposite: he confesses his lack of knowledge, prays to the Father, struggles with his will, obeys — and is finally exalted by God. Four lines show this unambiguously.

2.1 Dependence on the Father

Mark 13:32:
"But concerning that day or that hour, no one knows, not even the angels in heaven, nor the Son, but only the Father."

Jesus expressly excludes himself from knowledge of the time of the end. The Father alone knows it. Trinitarian attempts at explanation that here distinguish between a "divine" and a "human" nature of Jesus fail: one and the same person — Jesus — says of himself that he does not know something. A person with two states of knowledge is not a person but a construction.

John 5:30:
"I can do nothing on my own; as I hear, I judge."

Here Jesus emphasizes his complete dependence on the Father. He does not act autonomously, not by his own divine authority — he receives his commission and authority. An autonomous God cannot say that he can "do nothing on his own."

John 14:28:
"The Father is greater than I."

This statement of Jesus leaves no room whatsoever for an equality of Father and Son. "Greater" denotes superordination, not merely a functional distinction. Especially significant: Jesus does not relativize or explain this statement — he simply states it.

2.2 Prayer and obedience

A further strong counter-argument against the doctrine of the Trinity arises from the prayer life of Jesus and his explicit obedience to the Father.

Luke 6:12:
"In these days he went out to the mountain to pray, and all night he continued in prayer to God."

Jesus spends entire nights in prayer. He withdraws, seeks the nearness of God, and in prayer addresses himself to him. Were Jesus himself God, such praying would be unintelligible or even meaningless. God does not pray to God.

Luke 22:42:
"Father, if you are willing, remove this cup from me. Nevertheless, not my will, but yours, be done."

In this scene the difference between Jesus and God becomes especially clear. Jesus expressly distinguishes his will from the will of the Father and subordinates his will to the Father's. Two co-eternal, co-equal persons of a unified divine essence would have one will — not two, of which one is subordinated to the other.

2.3 Exaltation by God

Acts 2:36:
"Let all the house of Israel therefore know for certain that God has made him both Lord and Christ, this Jesus whom you crucified."

Jesus is not born as Lord, but made Lord. God is the subject — Jesus the object of the exaltation. What is made is not eternal.

Phil 2:9:
"Therefore God has highly exalted him and bestowed on him the name that is above every name."

The structure is clear: therefore — that is, because of his obedience — God has exalted Jesus. A God cannot be exalted, since there is nothing higher than God. Likewise God cannot receive a name, since he bears it from eternity.

2.4 Mortality

1 Tim 6:16:
"[God] alone has immortality."

This statement is of the greatest clarity. Immortality is not a general divine attribute that could belong to several persons at once — rather, God alone has it. Over against this, the New Testament testifies without any qualification that Jesus really died. Trinitarian explanations according to which only the "human nature" of Jesus died, while the "divine nature" remained untouched, do not solve the problem — they merely shift it into a construction of two natures that is not laid down in the text itself.

3. The Holy Spirit — God's power, not a third person

A further central component of the doctrine of the Trinity is the assumption that the Holy Spirit is an independent divine person — consubstantial with the Father and the Son. Yet Scripture itself does not know this conception. It speaks of the Holy Spirit consistently as God's power, breath, effective working — never as an independent subject.

Acts 1:8:
"You will receive power when the Holy Spirit has come upon you."

Here the Holy Spirit is explicitly connected with power. The Spirit is received, given, poured out — described not as a person, but as the effective presence of God.

Luke 1:35:
"The Holy Spirit will come upon you, and the power of the Most High will overshadow you."

This verse is especially instructive, since it contains a clear parallelism. "The Holy Spirit" and "the power of the Most High" stand synonymously. A third divine person is here neither necessary nor implied — the Spirit is the power of the Most High.

Ps 51:11:
"Take not your Holy Spirit from me."

David asks God not to take his Holy Spirit from him. The Spirit belongs to God ("your Holy Spirit") and is not an independent counterpart. He is that through which God works in human beings.

Sozzini illustrated this with a simple image: as the sun works through its rays, so God works through his Spirit. Rays are not a second sun — they are the action of the one sun. Thus the third pillar of the doctrine of the Trinity also proves to be unbiblical.

4. Logical breaks in the doctrine of three persons

Alongside the biblical counter-arguments, a sober logical examination shows that the doctrine of the Trinity is internally contradictory. It demands that one simultaneously hold as true statements that exclude one another — and appeals for this to "mystery." The following five breaks are decisive.

Break 1 — "one" and "three" at the same time

The doctrine claims: God is one and God is three. To avoid the contradiction, a distinction is drawn between "essence" (one) and "persons" (three). Yet this distinction does not exist in biblical usage. "One" in the OT and NT means consistently: not two, not three. A philosophical distinction that does not appear in the texts cannot dissolve the contradiction — it only confesses it.

Break 2 — consubstantiality and subordination

The Son is "consubstantial" with the Father — and at the same time "the Father is greater than I" (John 14:28). Consubstantiality excludes a difference in greatness. Whoever holds both to be true holds a contradiction to be true.

Break 3 — omniscience and not-knowing

Omniscience is a necessary attribute of God. Jesus, however, says of himself that he does not know the day of the end (Mark 13:32). A "double nature" does not save the matter: the not-knowing of a person is absolute, not relative — either she knows it or she does not.

Break 4 — immortality and death

God "alone has immortality" (1 Tim 6:16). Jesus has died. A dead person is dead — no living "divine part" can simultaneously keep the dead "human part" alive without the identity of the one person breaking apart.

Break 5 — prayer to oneself

If Jesus is God, then God prays to God. If Father and Son are the same essence, then one essence prays to itself. The scene in Gethsemane (Luke 22:42), however, shows two wills standing over against each other — and one subordinates itself to the other.

5. The historical emergence of the doctrine of the Trinity

Alongside the biblical and logical objections, church history also speaks unambiguously against the doctrine of the Trinity. It is no original component of the apostolic faith but the result of a dogmatic development over several centuries — under strong influence of Greek philosophy and imperial politics.

5.1 Early Christianity: one God, the Father

In the first decades and centuries of Christianity, clear and simple confessions of faith are found. There is one God, the Father, and one mediator, Jesus Christ, who is acknowledged as his envoy and Messiah. A doctrine of three co-eternal, consubstantial persons does not exist in this early phase. Neither Jesus nor the apostles taught it.

5.2 Council of Nicaea (325): philosophical concepts

A decisive turning point is the Council of Nicaea in the year 325. Here the term "consubstantial" (homoousios) was for the first time taken into the confession of faith — a term that appears nowhere in the Bible and whose philosophical origin (in Platonism) is unmistakable.

The council stood under the strong influence of the emperor Constantine the Great, who was less interested in theological truth-finding than in a uniform imperial religion. With this began a development in which ecclesiastical dogmas were no longer derived from the Bible but defined by authoritative conciliar decisions.

5.3 Council of Constantinople (381): codification

Only at the Council of Constantinople in the year 381 was the Trinity codified in its classical form. Here the Holy Spirit was also explicitly added as a third person. This temporal distance is decisive: a doctrine that is formulated only centuries after the apostles can hardly count as the original Christian confession.

5.4 Athanasian Creed: coercion instead of conviction

A particularly clear sign of the problem is the so-called Athanasian Creed, which operates with formulas of condemnation: whoever does not accept it cannot be saved. In place of biblical conviction comes here dogmatic coercion — instead of inviting to insight, a logically contradictory confession is declared necessary for salvation.

5.5 Sozzini's critique of the development of dogma

Fausto Sozzini sharply criticized this development. He showed that the doctrine of the Trinity does not stem from Scripture but from Greek philosophy. Sozzini argued: a doctrine that is not clearly taught in the Bible, that is formulated only centuries later, and is then enforced through imperial power and conciliar decrees, cannot possibly be the original faith of the apostles. Socinianism therefore understands itself not as an innovation but as a return to the apostolic confession.

6. Arguments from Sozzini's works

The critique of the doctrine of the Trinity presented here is not plucked from the air, but rests on a coherent argumentation that Fausto Sozzini systematically unfolded in several writings. Four works carry the burden: De Sacrae Scripturae Auctoritate (the methodological foundation), De Iesu Christo Servatore (Christology and the question of atonement), the Explicatio primae partis primi capitis Evangelii Iohannis (the interpretation of the prologue of John), and the Racovian Catechism as the systematic compendium of the Polish Brethren.

6.1 The authority of Holy Scripture — the scripture principle

In De Sacrae Scripturae Auctoritate (On the authority of Holy Scripture), Sozzini first defends the divine authority, credibility, and sufficiency of the biblical writings against rationalist and atheist objections. This positive defense, however, at the same time delivers the sharpest methodological blow against the doctrine of the Trinity — for from the scripture principle follow three principles that undermine any dogmatic Trinity:

1. Sufficiency: Scripture contains everything that is necessary for salvation. A doctrine that is not clearly taught in Scripture cannot be necessary for salvation.
2. Clarity (perspicuitas): Scripture is so clear in matters of salvation that any sincere reader can understand it. A doctrine that becomes accessible only through centuries of philosophical interpretation (essence vs. persons, homoousios) is not what the Bible itself teaches.
3. Precedence over tradition: Councils, confessions, and Church Fathers stand in need of interpretation — Scripture is the standard. The Trinity was set down by councils, not by clear scriptural words.

Sozzini therefore does not argue primarily: "The Bible says the opposite of the Trinity." Rather, much more fundamentally, he argues first: "If the Bible does not teach the Trinity with the clarity that would be required for a doctrine necessary for salvation, then it is not a binding article of faith — regardless of what tradition has made of it." This formal rejection strikes the doctrine of the Trinity at its weakest point: its dependence on extra-biblical concepts.

6.2 De Iesu Christo Servatore — Christology from the work of Christ

His main theological work De Iesu Christo Servatore ("On Jesus Christ the Savior") is at first glance a writing against the Reformation doctrine of satisfaction. Yet in its course Sozzini unfolds a complete Christology — and shows that the work of Christ itself does not require a consubstantial divinity, but excludes it.

The argument runs in two steps:

1. What Christ does presupposes his true humanity. He obeys (Phil 2:8), prays (Heb 5:7), learns (Heb 5:8), suffers, dies, and is raised. These acts are not "divine appearance" but real human enactments that can concern only a real human being. A second, "divine nature" that remained omniscient, immortal, and co-eternal alongside them would be theater.
2. What Christ accomplishes for us happens through God's act upon him. Christ is not Savior by his own authority, but because God raised him, exalted him, "made him both Lord and Christ" (Acts 2:36). The giver of authority is not the receiver of authority — the two are not identical.

6.3 Explicatio primae partis primi capitis Evangelii Iohannis

Sozzini's most extensive exegetical writing on Christology is his interpretation of the Johannine prologue (John 1:1–18) — the locus classicus of every trinitarian proof. There Sozzini shows in detail that the prologue precisely does not teach the personal pre-existence of a "God-Son," but the creative plan and the Word of God that became flesh in Christ:

• "In the beginning was the Word" (John 1:1) is not "in the beginning was a second person." The logos is God's self-interpreting counsel — he is "with God" as the plan with the planner, "God" in the sense that he is God's own speaking, not a second actor alongside God.
• "All things were made through him" (John 1:3) means the old creation in the mode of God's word, not a second creating person. Compare Ps 33:6: "By the word of the LORD the heavens were made." The Word creates without being a second being.
• "And the Word became flesh" (John 1:14) is the decisive break: only here, in the incarnation, does the personal existence of Christ begin. Before John 1:14 the prologue speaks of the plan; from John 1:14 on it speaks of the man in whom this plan took shape.

This reading dissolves at a stroke several tensions that remain unresolved on the trinitarian interpretation: why the "Son" worships the Father, why he does not know the day of the end, why he must be exalted. They are all intelligible from the standpoint of a true human being who embodies the Word and the will of God — not of a "second God" who pauses his divinity for the incarnation.

6.4 Racovian Catechism — the systematic teaching of the Polish Brethren

The Racovian Catechism (1605) gathers Socinian teaching in question-and-answer form. It explicitly devotes the Christology to the question whether Christ is "naturally God" — and denies it on a series of scripturally grounded reasons that anticipate, almost point by point, what is presented here.

Three lines of the Catechism are particularly powerful:

1. Christ is Son of God through mission and resurrection, not through eternal generation from the essence of God. "Son" in biblical usage is a title of relation and dignity (cf. "sons of God" for the angels, for the godly, for Israel) — not a metaphysical concept of essence.
2. Invocation of Christ is permitted and commanded — but as the invocation of the exalted mediator, to whom God has given all authority (Matt 28:18), not as prayer to a second God. The veneration of Christ takes place "to the glory of God the Father" (Phil 2:11).
3. Holy Spirit is God's power and effective working, not a third person. Where Scripture personifies the Spirit (he "speaks," "teaches," "is grieved"), it follows the same stylistic device with which it also lets wisdom, sin, or death speak.

6.5 The dispute over the invocation of Christ

A line of its own in the Socinian anti-Trinity critique is the inner-unitarian dispute over the invocation of Christ. Sozzini conducted it against the more radical Christian Francken and the non-adorationist Polish Brethren. He defended the position: Christ may be invoked — but as the one exalted by God, to whom all authority has been given, not as a consubstantial God.

This distinction is theologically decisive. It shows that worship does not imply consubstantiality. Whoever worships Christ can worship him as exalted Lord without taking him to be God himself — just as ancient Israel honored the king installed by God as the "Anointed" without taking him to be Yahweh. The trinitarian inference "worshiped → therefore God" is therefore not compelling, but a subsequent abridgement.

6.6 Synthesis of the sources

Whoever places the four writings side by side sees a consistent picture:

• De Sacrae Scripturae Auctoritate provides the method: only what Scripture clearly teaches is necessary for salvation.
• De Iesu Christo Servatore provides the Christology: the work of Christ requires his true humanity, not his consubstantiality with God.
• Explicatio Iohannis provides the exegesis of the key verses on which the Trinity is usually defended (John 1:1–18).
• Racovian Catechism provides the systematics in question-and-answer form for the congregation.

Three of these four works are available in German translation (see "Books"). Anyone who wishes to get to the bottom of the critique of the doctrine of the Trinity presented here will find there the arguments at full length — with all the objections, all the proof texts, and all the answers.

7. The ten decisive arguments

By way of overview — the arguments unfolded at length in sections 1–5, in compact form:

1. Shema Israel: Deut 6:4 confesses God as one — without inner-divine multiplicity.
2. Words of Isaiah: "Besides me there is no god" (Isa 43:10–11; 44:6) excludes any second or third person.
3. Jesus' self-statement in prayer: John 17:3 calls the Father alone the "only true God."
4. Paul's confession: 1 Cor 8:4–6 distinguishes clearly between "one God, the Father" and "one Lord, Jesus Christ."
5. Mediation: 1 Tim 2:5 expressly calls Jesus "the man Christ Jesus" as mediator — a mediator stands between parties, not above them.
6. Not-knowing: Mark 13:32 shatters the claim of omniscience.
7. Prayer and obedience: Luke 22:42 shows two wills — that is incompatible with "one essence."
8. Exaltation: Acts 2:36 and Phil 2:9 — God makes Jesus Lord; an eternal one is not "made."
9. Mortality: 1 Tim 6:16 — God alone has immortality; Jesus has died.
10. Spirit as power: Luke 1:35 sets "Holy Spirit" and "power of the Most High" synonymously — no second or third actor.

8. Biblical cross-references

Further passages that support the finding — for further reading and study:

• Deut 4:35, 39: "The LORD is God; there is no other besides him."
• 1 Kings 8:60: "… that all the peoples of the earth may know that the LORD is God; there is no other."
• Isa 45:5: "I am the LORD, and there is no other; besides me there is no god."
• Zech 14:9: "On that day the LORD will be one and his name one."
• Mark 12:29: Jesus himself cites the Shema Israel as the greatest commandment.
• John 8:40: "But now you seek to kill me, a man who has told you the truth."
• John 20:17: "I am ascending to my Father and your Father, to my God and your God."
• Acts 3:13: "The God of Abraham … glorified his servant Jesus."
• Rom 16:27: "To the only wise God be glory forevermore through Jesus Christ."
• 1 Cor 15:28: "… then the Son himself will also be subjected to him who put all things in subjection under him, that God may be all in all."
• Eph 1:17: "… the God of our Lord Jesus Christ, the Father of glory …"
• Rev 3:12: The exalted Christ speaks of "my God."

9. Common objections — and their answers

Trinitarian theology regularly brings the same scriptural passages into the field. They lose their weight as soon as one reads them in context and pays attention to what the texts themselves say — not to what tradition has made of them.

Objection 1: "Jesus is worshiped, therefore he is God."

Phil 2:11 expressly names the goal of the veneration of Jesus: "… to the glory of God the Father." Jesus is not worshiped as an independent God, but as the Lord exalted by God — and precisely this veneration is ultimately directed to the Father. John 5:23 confirms it: "Whoever does not honor the Son does not honor the Father who sent him." The honor is given to the one sent as one sent. Sozzini emphasized: God has conferred this position on Jesus — Jesus is venerated because God has exalted him, not because he is God.

Objection 2: "Jesus is eternal (Heb 13:8)."

"Jesus Christ is the same yesterday and today and forever" — the context (Heb 13:7–9) shows that what is at issue is the faithfulness and constancy of Christ toward his community, not a timeless existence. Other human beings too can in this sense remain "the same" without being eternal. The statement means: Jesus does not lose his identity — it does not make him God.

Objection 3: "Firstborn of all creation (Col 1:15) — therefore pre-existent."

In biblical usage, "firstborn" denotes not the chronologically first, but the preeminent, the heir, the one bestowed with authority (cf. Ps 89:27: David is called "firstborn" — although he was the youngest son of Jesse). In the context of the letter to the Colossians, Jesus is the firstborn with respect to the new creation — the first to be raised to imperishable life (Col 1:18: "the firstborn from the dead").

Objection 4: "I and the Father are one" (John 10:30).

A careful interpretation in context shows: Jesus speaks here not about his essence but about his work as shepherd. John 17:21 settles the question definitively: "That they may all be one, just as you, Father, are in me, and I in you, that they also may be in us." Here Jesus prays that his disciples may be "one" — in the same way as he is with the Father. Obviously consubstantiality of the disciples with God is not meant, but a unity of will, of task, and of love.

Objection 5: "Only God forgives sins."

Matt 9:8 is decisive here: "When the crowds saw it, they were afraid, and they glorified God, who had given such authority to men." The reaction is directed not at Jesus as God, but at God, who gives human beings — plural! — such authority. John 5:27 confirms it: "He has given him authority to execute judgment, because he is the Son of Man." Authority is given — it is not present by nature.

Objection 6: "Before Abraham was, I am" (John 8:58).

The verse is equated with Ex 3:14 ("I am that I am") — wrongly, on linguistic grounds. In Greek, John 8:58 has simply egō eimi without the function of a proper name; the LXX has in Ex 3:14 egō eimi ho ōn ("I am the One who is"). The context too speaks against the equation: Jesus emphasizes his preeminent position in the plan of salvation, not timeless existence. Cf. 1 Pet 1:20: "foreknown before the foundation of the world" — thought of in God's mind, not personally present.

Objection 7: "The Holy Spirit is offended, therefore a person."

In biblical Hebrew and Greek, non-personal entities are also personified: wisdom calls out, blood cries, the Spirit is grieved. Personification is a stylistic device — not proof of personality. The Spirit "is grieved" (Eph 4:30) just as God "is grieved," because the Spirit is the effective presence of God, not because he were a second actor alongside God.

10. Practical significance — a faith without the Trinity

For Socinianism, the rejection of the doctrine of the Trinity is not a purely theoretical or academic question. It has immediate consequences for prayer, discipleship, and the life of faith.

9.1 Prayer: to the Father — through Jesus

John 16:23:
"Whatever you ask of the Father in my name, he will give it to you."

Faith without the Trinity orders prayer unambiguously: it is directed to the Father, the only true God, and takes place in the name of Jesus, the mediator. Prayer thereby does not become more complicated, but clearer. It needs no inner-divine assignment of roles, no distinction between "the one God" and "the three persons."

9.2 Discipleship: Jesus as a real example

Heb 5:8–9:
"He learned obedience through what he suffered … and became the source of eternal salvation to all who obey him."

Jesus can be a genuine example only if he was really a human being. A God who only seems to suffer is no example for those who suffer. Jesus shows that obedience, trust, and love toward God are possible under human conditions. Following him is not "imitation of God" but learning from the man who trusted God perfectly.

9.3 Faith: free of paradoxes

A faith without the Trinity is free from inner contradictions. It does not demand that one hold opposites to be true at the same time. It is intelligible, teachable, and personally accountable. It invites examination, not submission to a dogmatically enforced mystery.

Sozzini emphasized that such a faith also shapes the ethics of the Christian. Whoever confesses a clear, one God and follows Jesus as an example arrives at a simple shaping of life — grounded in reason, Scripture, and love.

Already Fausto Sozzini showed that the true gospel does not consist in metaphysical speculations but in the simple message of the one God and his envoy. Whoever holds fast to this truth holds the truth as Scripture teaches it.
