The Bible is not the source. The Eucharist is the source and summit of the faith. Branches wither and die when they cut themselves off from the Eucharist. It's been 5+ centuries now for some of those branches, and they are in desperate need of the truth. There is a reason Islam is conquering Europe today. Too many people have believed for too long that everyone can discern the truth for himself, abandoning all tradition. I'm serious - the Bible is NOT the source of the faith. Apostolic Tradition (which the Bible is a part of) has much more to offer than just the Bible.
