I will subscribe to no creed of men, far less one that has been delivered on the point of a sword (no offense meant).
Yeshua taught Word, not creed.
But what has that to do with your question? I merely sought to answer from a sola-scriptura point of view. Early Christians were not without Scripture. They had the Tanakh. Ergo, Yeshua must be able to be discerned therein. I can find Him there.
"Do you believe in one Lord Jesus Christ, the only begotten Son of God, begotten of the Father before all ages, Light of Light, true God of True God, begotten not made of one essence with the Father, by Whom all things were made.....?"
Do you hold this belief?
