zerinus, you ignoring me?
Us Irish hate to be ignored.
I referenced some early letters from early Christians that believed in Trinity yet you claimed
claims of Christianity of three or four hundred years later, then that also does not agree with the claims of the earliest Christianity (or the Bible) either.
Take Trinitarian theology for example; there is no trace of that found in the Bible or in what the earliest Christians believed.
The Didache:
“After the foregoing instructions, baptize in the name of the Father, and of the Son, and of the Holy Spirit, in living [running] water. . . . If you have neither, pour water three times on the head, in the name of the Father, and of the Son, and of the Holy Spirit” (Didache 7:1 [A.D. 70]).
Ignatius of Antioch:
“[T]o the Church at Ephesus in Asia . . . chosen through true suffering by the will of the Father in Jesus Christ our God” (Letter to the Ephesians 1 [A.D. 110]).
“For our God, Jesus Christ, was conceived by Mary in accord with God’s plan: of the seed of David, it is true, but also of the Holy Spirit” (ibid., 18:2).
Justin Martyr:
“We will prove that we worship him reasonably; for we have learned that he is the Son of the true God himself, that he holds a second place, and the Spirit of prophecy a third. For this they accuse us of madness, saying that we attribute to a crucified man a place second to the unchangeable and eternal God, the Creator of all things; but they are ignorant of the mystery which lies therein” (First Apology 13:5–6 [A.D. 151]).
Theophilus of Antioch
“It is the attribute of God, of the most high and almighty and of the living God, not only to be everywhere, but also to see and hear all; for he can in no way be contained in a place. . . . The three days before the luminaries were created are types of the Trinity: God, his Word, and his Wisdom” (To Autolycus 2:15 [A.D. 181]).
I believe you have failed at the first hurdle.
How early you wanting it?
I believe St.Ignatius of Antioch was a student of the Apostle John yet he totally believed in the One Trinitarian God.
St.Ignatius of Antioch was among the Apostolic Fathers, was the third Bishop and Patriarch of Antioch, and was a student of
John the Apostle. En route to his martyrdom in Rome, Ignatius wrote a series of letters which have been preserved as an example of very early Christian theology. Important topics addressed in these letters include ecclesiology,
the sacraments, and the role of bishops.
