I came across this blog today about 'sola scriptura' and thought it was worth the read. The interrelation of Scripture and tradition is something I've been thinking about lately, especially since I've (finally) got around to getting back into Congar's The Meaning of Tradition. I don't have any cohesive thoughts on the issue at the moment, but wanted to post the link for consideration.
