Everything God INTENDED us to know of the life of Christ is written so we may believe..
Making doctrine out of silence is not an infallible process.. it is nothing more than guess work and the dreams of men
Remember when Paul spoke there was no "NT" as such.. the "traditions " have since been recorded in the scriptures
Col 2:8 Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ.
You assert that God did not intend us to know the Apostolic traditions unwritten in scripture? On what evidence?
