Sabellianism and the Trinity in Early Christianity
Early Christian writings reject Sabellianism and teach one God in Father, Son, and Holy Spirit. Gregory Thaumaturgus, Hippolytus, Tertullian, Dionysius of Rome, Novatian, and Origen all speak of real distinction between the persons while keeping one Godhead. Matthew 28:19, Matthew 3:17, and John 1:1 are the main Bible passages tied to this teaching.

What did early Christians believe about sabellianism and the Trinity?
Early Christian writings strongly reject Sabellianism and teach that the Father, Son, and Holy Spirit are real distinctions while still confessing one God. Writers like Gregory Thaumaturgus, Hippolytus, Tertullian, Dionysius of Rome, Novatian, and Origen all argue against making the Father and Son the same person, and many link this confession to baptism in the threefold name from Matthew 28:19.
The evidence is broad across the 1st to 3rd centuries and appears in theology, baptism, and liturgy, not just in anti-heresy works. There are some differences in how authors explain the Trinity, but the main line is clear: they did not treat Sabellianism as the church's teaching. Bible passages such as John 1:1, John 10:30, Matthew 3:17, and Matthew 28:19 are often used as key texts in this discussion, while 1 John 5:7 is not a secure early witness for these writers.

Questions Answered by the Sources
Did early Christians reject Sabellius by saying the Father, Son, and Holy Spirit are distinct?
Gregory Thaumaturgus, Hippolytus, Dionysius of Rome, and Novatian explicitly reject Sabellian ideas and distinguish Father, Son, and Holy Spirit. They pair that distinction with language about one God or one divine unity, rather than saying the three are the same person.

Gregory Thaumaturgus, A Sectional Confession of Faith Direct teaching
But some treat the Holy Trinity in an awful manner when they confidently assert that there are not three persons, and introduce the idea of a person devoid of subsistence. Therefore we clear ourselves of Sabellius, who says that the Father and the Son are the same. For he holds that the Father is He who speaks, and that the Son is the Word that abides in the Father, and becomes manifest at the time of creation, and afterward returns to God when all things are fulfilled. He makes the same claim also about the Spirit. We forswear this, because we believe that three persons—namely, Father, Son, and Holy Spirit—are declared to possess the one Godhead. For the one divinity, showing itself according to nature in the Trinity, establishes the oneness of the nature. And so there is a divinity that is the property of the Father, according to the word, "There is one God the Father," 1 Corinthians 8:6. And there is a divinity hereditary in the Son, as it is written, "The Word was God," John 1:1. And there is a divinity present according to nature in the Spirit, namely, what subsists as the Spirit of God, according to Paul's statement, "You are the temple of God, and the Spirit of God dwells in

Tertullian, Against Praxeas Direct teaching
..., when all the Scriptures testify to the clear existence of, and distinction in, the Persons of the Trinity, and indeed give us our Rule of faith: that He who speaks, and He of whom He speaks, and to whom He speaks, cannot possibly seem to be One and the Same. So absurd and misleading a statement would be unworthy of God: that, when it was Himself to whom He was speaking, He speaks rather to another, and not to His very self. Hear, then, other sayings also of the Father concerning the Son through the mouth of Isaiah: "Behold my Son, whom I have chosen; my beloved, in whom I am well pleased: I will put my Spirit upon Him, and He shall bring forth judgment to the Gentiles." Isaiah 42:1 Hear also what He says to the Son: "Is it a great thing for You, that You should be called my Son to raise up the tribes of Jacob, and to restore the dispersed of Israel? I have given You for a light to the Gentiles, that You may be their salvation to the end of the earth." Isaiah 49:6 Hear now also the Son's sayings about the Father: "The Spirit of the Lord is upon me, because He has anointed me to preach the gospel to men." He likewise speaks of Himself to the Father in the Psalm: "Forsake me not

...l come to him and make our dwelling with him." Moreover, He also added this: "But the Advocate, the Holy Spirit, whom the Father will send, He will teach you and bring all things to your remembrance, whatever I have said to you." He also speaks that passage in which He shows Himself to be the Son, and rightly adds, "If you loved me, you would rejoice because I go to the Father, for the Father is greater than I." But what shall we say when He also continues with these words: "I am the true vine, and my Father is the gardener. Every branch in me that does not bear fruit He takes away, and every branch that bears fruit He prunes, so that it may bear more fruit"? He still continues and adds, "As the Father has loved me, so I also have loved you. Remain in my love. If you have kept my commandments, you will remain in my love, just as I have kept the Father's commandments and remain in His love." Further, He also says, "I have called you friends, for all things that I have heard from my Father I have made known to you." Moreover, He adds to all this, "But they will do all these things to you for my name's sake, because they do not know Him who sent me." Since these statements, followi

How did early Christians explain one God and three persons?
The sources repeatedly say the Trinity is one God, one divine unity, or one divine nature, while still naming Father, Son, and Holy Spirit as distinct. This is the main pattern in Gregory Thaumaturgus, Origen, Cyprian, Dionysius of Alexandria, and the liturgical texts.

Gregory Thaumaturgus, A Sectional Confession of Faith Direct teaching
But if they say, "How can there be three persons, and yet only one Divinity?" we will give this reply: There are indeed three persons, since there is one person of God the Father, one of the Lord the Son, and one of the Holy Spirit. And yet there is only one Divinity, since the Son is the Image of God the Father, who is One. That is, He is God of God. In the same way, the Spirit is called the Spirit of God, and that by nature according to the very substance, not by a simple participation in God. And there is one substance in the Trinity. This is not also the case with things that are made. For there is not one substance in God and in the things that are made, because none of these is God in substance. Nor indeed is the Lord one of these in substance. But there is one Lord, the Son, and one Holy Spirit. And we also speak of one Divinity, one Lordship, and one Sanctity in the Trinity, because the Father is the Cause of the Lord, having begotten Him eternally, and the Lord is the Prototype of the Spirit. For in this way the Father is Lord, and the Son also is God. And of God it is said that God is a Spirit. John 4:24

Gregory Thaumaturgus, On the Trinity Direct teaching
I see in all three essentials: substance, genus, and name. We speak of man, servant, and curator. Man, because of substance. Servant, because of genus or condition. Curator, because of denomination. We also speak of Father, Son, and Holy Spirit. However, these are not names that only came later, but they are subsistences. Again, the denomination of man is not in actual fact a denomination, but a substance common to men, and it is the denomination proper to all men. Moreover, names are such as these: Adam, Abraham, Isaac, Jacob. These, I say, are names. But the Divine Persons are names indeed, and the names are still the persons. And the persons signify that which is and subsists, which is the essence of God. The name of the nature also signifies subsistence, as if we should speak of the man. All the persons are one nature, one essence, one will, and are called the Holy Trinity. These also are subsistent, one nature in three persons, and one genus. But the person of the Son is composite in its oneness, being one made up of two, that is, of divinity and humanity together. These two constitute one. Yet the divinity does not therefore receive any increment, but the Trinity remains as i

Origen, Commentary on John Direct teaching
...that the Son is second beside the Father, He being the same as the Father, while a distinction is clearly drawn between the Spirit and the Son in the passage, Matthew 12:32: “Whoever shall speak a word against the Son of Man, it shall be forgiven him; but whoever shall blaspheme against the Holy Spirit, he shall not have forgiveness, either in this world or in the world to come.” We consider, therefore, that there are three hypostases: the Father, the Son, and the Holy Spirit. At the same time, we believe that nothing is uncreated except the Father. Therefore, as the more pious and truer course, we admit that all things were made by the Word, and that the Holy Spirit is the most excellent and the first in order of all that was made by the Father through Christ. And this, perhaps, is the reason why the Spirit is not called God’s own Son. The Only-begotten alone is by nature and from the beginning a Son, and the Holy Spirit seems to need the Son to minister His essence to Him, so as to enable Him not only to exist, but also to be wise and reasonable and just, and all that we must think of Him as being. All this He has by participation in the character of Christ, of which we have s

Did early Christians baptize in the name of the Father, Son, and Holy Spirit?
The Bible cards and early Christian sources consistently preserve the baptismal formula naming Father, Son, and Holy Spirit. The Didache, Apostolic Constitutions, Cyprian, and Ignatius all reflect this pattern, and Matthew 28:19 provides the core Bible passage.

Cyprian, Epistles Direct teaching
... baptizing them in the name of the Father, and of the Son, and of the Holy Ghost.” He points to the Trinity, in whose sacrament the nations were to be baptized. Does Marcion, then, uphold the Trinity? Does he confess the same Father, the Creator, as we do? Does he know the same Son, Christ born of the Virgin Mary, who as the Word was made flesh, who bore our sins, who conquered death by dying, who by Himself first began the resurrection of the flesh, and showed His disciples that He had risen in the same flesh? Marcion’s faith is completely different, and so is that of the other heretics. No, with them there is nothing but treachery, blasphemy, and strife, which is opposed to holiness and truth. How then can someone who is baptized among them seem to have received remission of sins and the grace of divine mercy by his faith, when he does not have the truth of the faith itself? For if, as some think, a person could receive anything outside the Church according to his faith, then he certainly has received what he believed. But if he believes what is false, he could not receive what is true. Rather, he has received things corrupted and profane, according to what he believed.

...ord be united with the God of all, and that the Holy Spirit abide and dwell in God. Thus the Divine Trinity must be brought together and gathered into one, as into a certain head, that is, into the all-powerful God of all. For the teaching of the foolish Marcion, which cuts up and divides the monarchy into three elements, is certainly from the devil, and not from Christ's true disciples or from those to whom the Savior's teaching is pleasing. For they rightly know that the Trinity is declared in the divine Scripture, but the teaching that there are three gods is taught neither in the Old Testament nor in the New Testament.

Hippolytus, Against the Heresy of Noetus Supporting witness
... someone say that he speaks of two Gods? I certainly will not speak of two Gods, but of one; of two Persons, however, and of a third divine arrangement, that is, the grace of the Holy Spirit. For the Father indeed is One, but there are two Persons, because there is also the Son; and then there is the third, the Holy Spirit. The Father decrees, the Word carries out, and the Son is manifested, through whom the Father is believed on. The harmonious divine arrangement is led back to one God, for God is One. It is the Father who commands, and the Son who obeys, and the Holy Spirit who gives understanding. The Father is above all, and the Son is through all, and the Holy Spirit is in all. And we cannot otherwise think of one God, except by truly believing in Father and Son and Holy Spirit. For the Jews glorified, or gloried in, the Father, but did not give Him thanks, for they did not recognize the Son. The disciples recognized the Son, but not in the Holy Spirit; therefore they also denied Him. The Father's Word, therefore, knowing the divine arrangement and the will of the Father, namely, that the Father seeks to be worshipped in no other way than this, gave this charge to the disci
