I’ve heard various non-Trinitarian religious groups and scholars claiming that early Christians did not teach the doctrine of the Trinity, and then pointing to the writings of the Church Fathers to support their claims.
Rather than reading isolated quotations which may or may not be in their proper context, I decided to read the writings of the earliest Church Fathers myself to see what they say. What I found clearly supports the doctrine of the Trinity.
Two Key Issues
By the Trinity, I mean that within the nature of the one true God there are three distinct Persons: the Father, the Son, and the Holy Spirit. Typical objections are that (1) the Spirit is not a person, but rather an impersonal divine force, and (2) the Son (Jesus) is not divine.
Well, what exactly did early Christians believe?
The Personality and Deity of the Holy Spirit
In The First Epistle of Clement to the Corinthians, we find that the Holy Spirit is alive and is a person:
As surely as God lives, as Jesus Christ lives, and the Holy Ghost also (on whom are set the faith and hope of God’s elect)…
(The First Epistle of Clement to the Corinthians, 58) 1
Note that this passage tells us that (1) the Holy Spirit is not an impersonal force, but rather is alive (he “also” lives) and (2) the Holy Spirit is a person not an “it” (“on whom” our hopes are set, not “on which”).
The introduction to the edition I read explains that this epistle “is one of the earliest Christian writings outside the New Testament… Of the authenticity of this epistle there is no doubt. Its author was the Clement who is mentioned fourth (after Peter, Linus and Anencletus) in the most reliable lists of the Bishops of Rome… The date of the epistle is generally reckoned to be about A.D. 96.” 2
The Divinity of Jesus
Ignatius, Bishop of Antioch, was a student of the Apostle John. Prior to being martyred in A.D. 107, Ignatius penned or dictated seven letters. His writings drip with language about the divinity of Jesus:
Ignatius…to the Church at Ephesus in Asia; a church…forever united and chosen, through real suffering, by the will of the Father and Jesus Christ our God… Being imitators of God, you have, once restored to new life in the Blood of God, perfectly accomplished the task so natural to you.
(Ignatius, Epistle to the Ephesians, prologue and ch. 1) 3
There is only one Physician –
Very flesh, yet Spirit too;
uncreated, and yet born;
God-and-Man in One agreed,
Very-Life-in-Death indeed,
Fruit of God and Mary’s seed;
At once impassible and torn
By pain and suffering here below:
Jesus Christ, whom as our Lord we know.
(Ignatius, Epistle to the Ephesians, 7) 4
Jesus Christ our God was conceived by Mary of the seed of David and of the Spirit of God… The age-old empire of evil was overthrown, for God was now appearing in human form to bring in a new order, even life without end. (Ignatius, Epistle to the Ephesians, 18 and 19) 5
All perfect happiness in Jesus Christ our God, to you who are bodily and spiritually at one with all His commandments… (Ignatius, Epistle to the Romans, prologue) 6
Leave me to imitate the Passion of my God. (Ignatius, Epistle to the Romans, 6) 7
Glory be to Jesus Christ, the Divine One… (Ignatius, Epistle to the Smyrnaeans, 1) 8
Farewell always in our God Jesus Christ. (Ignatius, Epistle to Polycarp, 8 ) 9
This last quotation is especially noteworthy. Here Ignatius is writing to another disciple of the Apostle John, Polycarp the Bishop of Smyrna. If Ignatius were making a doctrinal error in calling Jesus God, surely Polycarp would have corrected him. However, we see the opposite occur: after Polycarp received this letter and copies of the other letters penned by Ignatius, Polycarp had them copied and circulated to the various churches in the region – in essence validating their doctrinal content!
Conclusion
Going back to the earliest Christian writings outside of the New Testament, we find powerful testimony that the Holy Spirit was considered to be a person by early Christians and that Jesus Christ was truly God in the flesh. From these passages, it’s clear that the earliest Christians were indeed Trinitarian.
