I’m late to the argument, and haven’ had time to read all the posts yet. Has someone mentioned the fact that the Bible was not “officially” formed until 300-400 years after Christ? That alone defeats the Sola Scriptura argument - you can’t claim by Scripture alone when there was no official Scripture to follow. That’s why sacred tradition is hand-in-hand with the Word, with neither above the other. And if you read the Catholic Catechism, you’ll find that every aspect of Catholic doctrine has biblical support.
No official canon or ‘bible’ per se until the Vulgate, and Pope Gelasius.
Thanks for the backup.
