Union with God in Christ

Early Christian writings teach that people come into union with God through Jesus Christ, by faith, the Holy Spirit, baptism, and the Eucharist. Ignatius, Irenaeus, Clement of Alexandria, Tertullian, and Cyprian all connect this union with fellowship, holiness, and life. The Bible passages most often used here are 1 John 1:3, 1 Corinthians 10:16, Romans 8:17, and 2 Peter 1:4.

What did early Christians believe about union with God in Christ?

Early Christian writings teach that union with God comes through Christ, not by collapsing the Father and the Son into one person. Writers like Ignatius, Irenaeus, Clement of Alexandria, Tertullian, and Cyprian speak of fellowship with the Father and the Son, being joined to Christ, sharing in the Holy Spirit, and becoming one body through baptism and the Eucharist. The strongest and most repeated theme is communion with Christ that brings life, adoption, holiness, and hope of resurrection.

The evidence is broad and early, though some passages are more about the Eucharist, church unity, or the Trinity than about deification in the later technical sense. A few later or weaker lines about becoming “God” or “deified” are present, but they are not needed to make the main case. Many more early Christian quotations, Bible passages, and source links are gathered below so you can study the evidence for yourself.

Key Takeaways

  • Early Christians linked union with God to fellowship with the Father and the Son through Christ.
  • They often connected this union with the Holy Spirit, baptism, and the Eucharist.
  • They also spoke of sharing in Christ’s life, suffering, and inheritance.
  • Some later lines use strong language like 'deified,' but the main pattern is communion and adoption.

Questions Answered by the Sources

Did early Christians teach fellowship or communion with God through Christ?

The strongest witnesses say believers have fellowship with the Father and the Son through Christ, are called into the Son’s fellowship, and are brought near to God by Christ's blood. Early writers repeat that Christians live in Christ, have communion with Him, and receive access to God through him.

They share in His divine influence and in the gift of the Holy Spirit. They are armed through Jesus and have received His fear into their hearts. They enjoy the benefit of being sprinkled with the precious and innocent blood of Christ. They have full freedom to call Almighty God "Father," being fellow heirs and joint partakers with His beloved Son. Listen to this holy teaching, you who enjoy His promises, since it has been delivered by the command of your Savior and agrees with His glorious words. Take care, you children of God, to do all things in obedience to God, and in all things please Christ our Lord. For if anyone follows unrighteousness and does those things that are contrary to the will of God, such a person will be regarded by God as one of the disobedient heathen.

Did early Christians say believers are joined to Christ or become partakers of Christ?

The sources say believers are in Christ, united with Him in death and life, and made partakers of Christ and joint-heirs with Him. Several early writers describe this as being united with Christ, sharing His body, and living in him.

    When, therefore, the mixed cup and the made bread receive the Word of God, and the Eucharist of the blood and body of Christ is formed, from which the substance of our flesh is grown and sustained, how can they claim that the flesh is incapable of receiving the gift of God, which is eternal life, when this flesh is nourished from the body and blood of the Lord and is a part of Him? Just as the blessed Paul states in his letter to the Ephesians, that “we are members of His body, of His flesh, and of His bones.” He does not speak of some spiritual and invisible person, for a spirit does not have bones or flesh; but he is referring to the arrangement by which the Lord became an actual man, consisting of flesh, and nerves, and bones,—that flesh which is nourished by the cup that is His blood, and grows from the bread that is His body. And just as a branch from the vine planted in the ground bears fruit in its season, or as a grain of wheat falling into the earth and breaking down, rises with abundant growth by the Spirit of God, who holds all things, and then, through the wisdom of God, serves human use, and having received the Word of God, becomes the Eucharist, which is the body and

Yet it would be better for them to treat it with respect, so that they might also rise again. It is fitting, therefore, that you should keep away from such people, and not speak of them either in private or in public, but to pay attention to the prophets, and above all, to the Gospel, in which the passion of Christ has been revealed to us, and the resurrection has been fully proven.

He says, "I am the Bread of Life," John 6:35. And, a little above, "The Bread is the Word of the living God, who came down from the heavens," John 6:33. Then we find, too, that His body is counted in bread: "This is my body," Matthew 26:26. And so, in asking for daily bread, we ask for perpetuity in Christ and indivisibility from His body. But because that phrase can also be understood in a bodily sense, it cannot be used that way without the religious remembrance of spiritual Discipline as well. For the Lord commands that bread be prayed for, which is the only food necessary for believers. For all other things the nations seek after, Matthew 6:32. He teaches the same lesson both by examples and repeatedly in parables, when He says, "Does a father take away bread from his children, and hand it to dogs?" And again, "Does a father give his son a stone when he asks for bread?" For in this way He shows what sons expect from their father. No, even that man knocking at night knocked for bread, Luke

    This food is called among us [the Eucharist], and only those who believe that our teachings are true, have been washed with the washing for the remission of sins and renewal, and live as Christ instructed, are allowed to partake. We do not receive these as common bread and drink, but in the same way that Jesus Christ our Savior became flesh by the Word of God and had flesh and blood for our salvation, we have been taught that the food blessed by His word and prayer, which nourishes our blood and flesh through transformation, is the flesh and blood of Jesus who became flesh. The apostles, in the writings they composed, which are called Gospels, have passed down to us what Jesus instructed them: that He took bread, gave thanks, and said, "Do this in remembrance of Me, this is My body;" and in the same way, after taking the cup and giving thanks, He said, "This is My blood;" and gave it to them alone. The wicked devils have imitated this in the mysteries of Mithras, commanding the same actions.

Still, it was not in the morning, but after supper, that the Lord offered the mixed cup. Should we then celebrate the Lord's cup after supper, so that by constantly repeating the Lord's Supper we may offer the mixed cup? Christ had to offer it toward the evening of the day, so that the very hour of the sacrifice might show the decline and evening of the world, as it is written in Exodus 12:6, "And all the people of the synagogue of the children of Israel shall kill it in the evening."

But we ought to know and remember that it is written, “Let not the oil of a sinner anoint my head,” which the Holy Spirit warned about beforehand in the Psalms, lest anyone who has gone out of the way and wandered from the path of truth should be anointed by heretics and adversaries of Christ.

For who is more a priest of the Most High God than our Lord Jesus Christ? He offered a sacrifice to God the Father, and He offered that very same thing which Melchizedek had offered, that is, bread and wine, namely, His body and blood.

Who has been able to discern its union with his body? This one thing is all we know certainly, that there is a soul within us joined with the body. Thus then we reason and believe that the Word is begotten by the Father, although we neither possess nor know the clear rationale of the fact. The Word Himself is before every creature, eternal from the Eternal, like spring from spring, and light from light. The word Word, indeed, belongs to those three genera of words which are named in Scripture, and which are not substantial: namely, the word conceived, the word uttered, and the word articulated. The word conceived certainly is not substantial. The word uttered, again, is that voice which the prophets hear from God, or the prophetic speech itself. And even this is not substantial.

Philip is rebuked, and rightly and deservedly, because he said, "Lord, show us the Father, and it is enough for us." For when had he ever heard from Christ, or learned, that Christ was the Father? On the contrary, he had often heard and often learned that He was the Son, not that He was the Father. For when the Lord said, "If you have known me, you have known my Father also; and from now on you have known Him and have seen Him," He did not say this because He wanted to be understood as the Father Himself. Rather, He meant that the person who came near to the Son of God completely and fully, with all faith and all reverence, would certainly reach the Father through the Son Himself, in whom he believes, and would see Him. For He says, "No one can come to the Father but by me."

And when Christ our life is revealed, then those who are worthy to be revealed with Him in glory will also be revealed with Him, Colossians 3:3-4. But the enemy of this life, who is also the last enemy of all His enemies to be destroyed, is death, 1 Corinthians 15:26. The soul that sins dies by having a condition opposite to the one found in the soul that lives rightly, and because it lives rightly, truly lives. And when it is said in the law, "I have placed life before your face," Deuteronomy 30:15, Scripture says this about Him who said, "I am the Life," and about His enemy, death. By his deeds, each of us is always choosing one or the other. And when we sin while life is before our face, the curse is fulfilled against us which says, "And your life shall be hanging up before you," and so on, down to the words, "and for the sights of your eyes which you shall see," Deuteronomy 28:66-67.

He is always the same and admits no increase or decrease. He gave to us the Law, the prophets, and the Gospels. He is Lord of the patriarchs and apostles, and of all the saints. And we believe in one Lord Jesus Christ, the only begotten Son of God. He was not begotten from things that are not, but from Him who is the Father.

  3. Dionysius of Alexandria, Exegetical Fragments Supporting witness

    Early Christian Writings · Primary Text · 3rd c. · Ante-Nicene Fathers Volume #6
    ...thing should not be done, which is His own, and begs that the superior should be done, which is His Father's, namely, the divine will. Yet, in respect of the divinity, it is one and the same will in Himself and in His Father. For it was the Father's will that He should pass through every trial, that is, temptation. And the Father Himself in a marvelous manner brought Him on this course. Not indeed with the trial itself as His goal, nor simply in order that He might enter into it, but in order that He might prove Himself to be above the trial, and also beyond it. And surely the Saviour asks for neither what is impossible, nor what is impracticable, nor what is contrary to the Father's will. It is something possible. For Mark mentions His saying, "Abba, Father, all things are possible to You," Mark 14:36. And they are possible if He wills them. For Luke tells us that He said, "Father, if You are willing, remove this cup from me," Luke 22:42. Therefore the Holy Spirit, apportioned among the evangelists, makes up the full account of our Saviour's whole disposition by the expressions of these several narrators taken together. He does not then ask of the Father what the Father does no

Common Questions

Did early Christians teach that believers could be united with God?

Yes. They often said believers have fellowship with the Father and the Son through Christ and the Holy Spirit, and they tied that union to life, holiness, and adoption.

Did they connect union with God to the Eucharist?

Yes. Several early writers said the Eucharist is communion with Christ’s body and blood and linked it with life in Christ.

Did early Christians say believers become God in the same way Christ is God?

Not in a simple equal sense. The stronger and more common teaching is that believers are joined to God, made partakers of Christ, and given life in him.
