On the other hand, I've shown many places where it says we need Sacred Tradition (not any-ol' "huma" tradition, but Sacred Tradiion, the kind Paul insisted we "hold fast to") and the teaching authority of the Church:
2 Tim. 3:14,17
2 Thess. 2:15
Luke 10:16
Matthew 18:17
1 Tim 3:15
Throughtout history, many individuals and whole tribes and clans had the Faith, were received in the Church, were saved by Jesus their Savior, without having any access to written Scriptures. Books were extremely few and rare in history before movable type. Not an ideal situation, but nevertheless a true, historical situation. Huge numbers of people were illiterate. Huge numbers of people for many generations periods couldn't get Scriptures in their native tongue. Evennow you can hardly find it in Tuareg or Pashto or many other languages.
St. Stephen deacon, the first martyr, never held a single book of the New Testament in his hand, never laid eyes on it. Every single person mentioned in the Bible lived their Faith without the full OT and NT (with the possible exception of St. John.)
They learned about Our Lord through Oral Tradition --- preaching, teaching, prayers they were taught, songs, liturgy --- and example.
Amirite?

Aside from those traditions of the apostles we find in the Scriptures, what other traditions do we need?
