Lol! We were there from the foundation of the Church.
The Bible Itself states that there are "oral" teachings and traditions that are to be carried on to the present-day (2 Thessalonians 2:15; 1 Corinthians 11:2; 2 Timothy 2:2; Romans 10:17; 1 Peter 1:24-25). These teachings are what the Catholic Church considers "Sacred Apostolic Tradition." This type of "Tradition" never changes because it was passed down by the Apostles themselves. It is not the same as the man-made traditions condemned in Scripture. The man-made traditions condemned in Scripture were those of the Jewish Pharisees. In fact, as Christians, we are suppose to disassociate ourselves from persons who do not follow Apostolic Tradition (2 Thessalonians 3:6). If oral tradition is not to be followed, why did St. Paul state Christ said something that is not recorded in the Gospels (Acts 20:35)? St. Paul must have "heard" this saying, not read it from any Gospel or "Scripture," thereby, proving that some things Christ said were not recorded in the Gospels (John 21:25) and were passed on orally among His disciples instead, but were just as valid as anything written since St. Paul himself used one of these oral passages in one of his own epistles.
And what oral teachings are these, and by what proof do you have that they come from the apostles themselves?
