It’s rather simple really. There are many who claim “Sola Scriptura” but stray from it. Show me the differences between “denominations”, sects, individuals or whatever and I can show how they stray from Sola Scriptura. They either don’t use ALL of scripture, take passages out of context, or use some other “authority” such as Luther, Calvin, so called church fathers, or some other “source” for their justification for a belief.
You don't use any sources? At all? You have never read and been convinced by any person's explanation of a Scriptural passage? You've never heard something explained by someone else? You don't listen to any preachers on Sunday?
It's just you and you alone, reading the Bible, staying blissfully "pure" of any outside influence?
Post #14 case in point.
