Yes it would, and that's why I placed a smile/wink/grin face behind it. You and I both know it doesn't have to be in the Bible to be a Catholic belief.Which says ---??
25 And there are also many other things that Jesus did, which if they were written one by one, I suppose that even the world itself could not contain the books that would be written. Amen
So if now the rule of "sola scriptura" is that anything we want to claim about Christ is automatically true - via an appeal to what we do not find in scripture, I am thinking that we could then argue "Christ said - beware lest at any future point in time you be tricked into joining something called the Catholic church".
And then when someone says "where in the world did Jesus ever say such a thing according to scripture?" -- we simply respond John 21:25??
That would be the "Wild wild west" in terms of Bible doctrines.
in Christ,
Bob
