Even if I were an atheist, which I am not, the answer is yes. Teaching doctrine does not require a belief that God exists. Besides, most of my life I was a practicing Christian, so yes I do know the faith.
What does Jesus say, not what does an unbeliever say ? Provided it was John quoting Jesus, but that's another topic. Not enough time today.
But since you are quoting from John why not mention the part where Jesus calls the Father his God???? [John 20:17] Or where John quotes Jesus saying "the Father is greater than I"? [John 14:28]
What are we to draw from these quotes? That Jesus was no God, or that he was a lesser God? Sure seems that way, doesn't it? It is no wonder early Christian apologetics were teaching that Christ was a man who was either "made" divine (Adoptionism) or that he was a "lesser God" (Ariansm).
The Church had to establish Trinitarian and Christological dogma to counter this, because the Church did not believe that Christ was a creature made divine, or a lesser God, even though that is exactly what the Bible suggests.
The Church believed and still believes that all three divine hypostases are co-eternal and co-equal and equally divine. This is not in the scirptures but even the scirptures tell you that not everything Jesus taught has been written down, and that he revealed the secrets (mysteries) of the kingdom of heaven to his disicples, who passed it on to theirs (hence the importance of apostolic succession, whether you agree with it or not).
Of course, once you reject all but the incomplete scriptures, and go only by what they say, then you have "Christianity" where Christ is the Father's errand boy and it's called Portestantism or better yet, the Portestant heresy, i.e. something the Church never taught.
Suffice it to say that all these verses you post represent interpolations from the standpoint of a Jewish messiah, and not the Platonic Logos incarnate. In other words, Jesus in his humanity and not in his divinity.
What you know or believe you know has not even convinced you..there is no reason to even read what you write if you can not convince yourself.. Only the lost can take it seriously
