I'm going to show you something that might blow your mind.
It concerns a very popular verse in the Bible, and it certainly blew my mind - even after years of knowing (and quoting) the verse, having been raised in Christian culture. It's a simple and yet very pervasive error of interpretation. A wrong understanding which has become the dominant understanding.
If you are one who knows this saying to be taken from scripture, you might be immediately defensive at the idea of me criticizing it... But let me ask you a question the people who use this phrase in sermon after sermon never ask: Is it really "scriptural" to repeat "Your works are filthy rags" in the way we do? Are you certain? Just because the phrase is in the Bible - does that mean we're using it properly or for the same reason? Is it even a correct perspective to take in holding it over the heads of others?
You may have already guessed (you're fairly clever, after all) that I don't think the answer to any of the above questions should be "yes."
