Does this question presume that the Church is outside of scripture?
Can a non-believer, stranded alone, with only a Bible to go on, or even just part of one, be saved? Food for thought.
Sure. Even a non-believer without the scriptures can be saved. God is loving and merciful.

I don’t see how the church could be outside of something that specifically references it. Of course this opens another entire world of controversy.
