Pope Shenouda III
After the Lord's resurrection, we find the same situation. The Lord met the two disciples of Emmaus, and "beginning at Moses and all the Prophets, He expounded to them in all the Scriptures the things concerning Himself" (Lk. 24: 27). All these teachings, and others, were not recorded in the Gospels. But undoubtedly they, or some thereof, have reached us through Tradition.
