You lost me as soon as you quoted Timothy, which was probably not written by Paul but rather a 2nd century writer using Paul's name to create authority for himself. And your arguments that Paul was cognizant of the now-canonical gospels assumes he got his text from them. More likely, they got the text from him. Paul states clearly that he took NO instruction from men but rather got all his information through direct revelation from God. You might wish to pick up copies of The Authoritative Letters of Paul, by a team of biblical scholars, and Forged, by Bart D. Ehrman. There are many others, but those two books would be a good start.
