Do you believe that Sola Scriptura is a tradition of men or of the apostles?
Do you guys believe the apostles taught Sola Scriptura, or was it invented later built upon the apostles teachings ?
I'm not presuposing that Sola Scriptura is the 66 books, even if that it's seems to be a necessary condition for it to work in real life, but only that they taught that only what the Scripture (whatever that be), is what people can be bound to believe, to be the rule of faith.
Some people in the comments shrink the definition of Sola Scriptura to be merely that the Church can bind people to believe in other things that are not found in the scripture, but they can't call that infallible, but it's completely anachronistic, the reformation in Switzerland started because the people refused to keep Lent, I don't think the Church was teaching that Lent was infallible, but that they should be bound to follow anyway. And Luther says in diet of worms that he won't follow popes and councils, but he must be convinced by the scripture only, I don't think he viewed their authority as something that could bind his conscious even if they weren't infallible.
I can cite here a bunch of authoritative protestants documents saying the same, but I don't want to make that too long, so I'm gonna put in a comment here.
My only question is whether you believe that the apostles taught the Bible as the only rule of faith for the church.
