Lets look at some contemporary writers of Paul, and what they said about Jesus. And the idea of a trinity God.
Phil: 4:3: And I intreat thee also, true yokefellow, help those women which laboured with me in the gospel, with Clement also, and with other my fellowlabourers, whose names are in the book of life.
Clement (ca 85 A.D)
Clement acknowledges that there is One Almighty God and one Christ. He taught that the creator of the universe is the Father.
“The church of God which sojourns at Rome, to the church of God sojourning at Corinth, to those who are called and sanctified by the will of God through our Lord Jesus Christ. Grace to you, and peace, be multiplied, from Almighty God through Jesus Christ.
For Christ is of those who are humble, and not of those who Lord over his flock. Our Lord Jesus Christ, the sceptre of the majesty of God, did not come in pomp of pride or arrogance, although He might have done so, but in a humble state.” (16).
Let us look steadfastly to the Father and Creator of the universe. (19).
All these the great Creator and Lord of all has appointed to exist in peace and harmony, while He does good to all, but most abundantly to us who have fled for safety to His compassions through Jesus Christ our Lord, to Whom be glory and Majesty for ever and ever. Amen. (20)
calls upon His glorious and holy Name, faith, fear, peace, patience, longsuffering, self-control, purity, and sobriety, to the well pleasing of His Name, through our High Priest and Protector, Jesus Christ, through whom be to Him glory, and Majesty, and power, and honour, both now and for evermore. Amen. (58).
The grace of our Lord Jesus Christ be with you, and with all everywhere that are the called of God through him, through whom be to Him glory, honour, power, Majesty, and eternal dominion, from everlasting to everlasting. Amen. (59).”
Paul thought highly of Clement, he considered him saved.
Rom: 16:14: Salute Asyncritus, Phlegon, Hermas, Patrobas, Hermes, and the brethren which are with them.
Hermas (ca. 100 A.D)
Hermas acknowledged one God who created all things by his powerful word and great wisdom.
“First, believe that there is one God who created and framed all things, and made all things out of nothing. (Commands, 1).
The God of powers, who by his invisible mighty power and great wisdom has created the world, and by His glorious counsel has beautified his creation, and by his powerful word has fixed the heavens and laid the foundations of the earth upon the waters.” (Visions, 1, 3)”
Paul called Hermas brother.
Three other writers of that time before the trinity creed was adopted.
Ignatius of Antioch (ca. 110 A.D)
Ignatius, who is Theophorus, to the Church which has received grace through the greatness of the Father Most High. (Third Epistle).
I have learned that certain of the ministers of Satan have wished to disturb you, some of them asserting that Jesus was born [only] in appearance, was crucified in appearance, and died in appearance, others that He is not the Son, the Creator, and others that He is Himself God over all. (To the Tarsians, II).
Polycarp
Polycarp taught that God Almighty is the Father and his son is Jesus Christ.
To the Philippians
Polycarp and the elders with him. To the Church of God sojourning in Philippi. Mercy and peace from God Almighty and Jesus Christ our Saviour be multiplied to you.
Now may God and the Father of our Lord Jesus Christ, and the eternal priest himself, Jesus Christ, the Son of God, build you up in faith and truth... to all under heaven who shall believe in our Lord Jesus Christ and in his Father who raised him from the dead. (12).
Papias (ca. 110-130 A. D)
Papias taught clearly how God will redeem creation back to himself. He said Christ reigns by God’s will and will conquer all God’s enemies. Even Jesus Christ himself will be subject to God, so God may be in all.
The presbyters, the disciples of the apostles, say that this is the gradation and arrangement of those who are saved, and that they advance through steps of this nature, and that, moreover, they ascend through the Spirit to the Son, and through the Son to the Father, and that in due time the Son will yield up his work to the Father, even as it is said by the apostle, “For he must reign until he has put all enemies under his feet. The last enemy that shall be destroyed is death.” For in the times of the Kingdom the righteous man who is on the earth shall forget to die. “But when He says all things are put under him, it is manifest that He is excepted Who did put all things under him. And when all things shall be subjected to him, then shall the Son also himself be subject to Him, Who put all things under him, that God may be all in all.” (Fragments of the Exposition of the Oracles of the Lord, 5).
