You might consider looking at the Early Church Fathers then who were definitely Catholic.
The Early
Church Fathers are also known as the
Apostolic Fathers. Yet there is definitely no proof they thought what the Catholic Church taught. Actually it quite well proves the opposite of your claim. Of the earliest Christian statements found in
The Didache, or the Teaching of the Twelve Apostles which historians date before the year 100 CE, in which Matthew 28:19 mentions the Father, Son, Holy Spirit yet
never states they are equal in eternity, power, position or wisdom. No trinity at all, and in
The Influence of Greek Ideas on Christianity Edwin Hatch comments about the Didache that "In the original sphere of Christianity there does not appear to have been any great advance
[change] upon these simple concepts. The doctrine upon which stress was laid was, that God is, that He is one, that He is almighty and everlasting, that He made the world, that His mercy is over all His works.
There was no taste for metaphysical discussion.” (1957, page 252)
There was no change to the Biblical teaching that Christ is subordinate to God Almighty, as the Bible alone teaches that.
That is why there could not have existed any discussion or debate on the equality because the teachings were still valid… that is what the Apostolic Fathers detail about, not in favor of Catholicism as proof of their writings show.
Clement of Rome makes no mention of a Trinity, either directly or indirectly in the
First Epistle of Clement to the Corinthian, "The apostles have preached the Gospel to us from the Lord Jesus Christ; Jesus Christ has done so from God.
Christ therefore
was sent forth by God, and the apostles by Christ.”
“May
God, who seeth all things, and who is the Ruler of all spirits and the Lord of all flesh—
who chose our Lord
Jesus Christ and us through Him to be a peculiar people—grant to every soul that calleth upon His glorious and holy Name, faith, fear, peace, patience, long-suffering.” (
The Ante-Nicene Fathers, Alexander Roberts and James Donaldson, editors, American Reprint of the Edinburgh Edition, 1885, Volume I, pages 5, 16, 21)
Clement does not say that Jesus or the holy spirit is equal to God. He presents Almighty God (not just “Father”) as distinct from the Son. God is spoken of as superior, since Christ is “sent forth” by God, and God “chose” Christ. Showing that God and Christ are two separate and unequal identities. Clement never viewed Jesus as sharing in a godhead with the Father, we know here is no Trinity in Clement’s writings.
