Oh, it's irrelevant, if you really do accept the facile formula at face value. I don't. I'm not alone in that thought, either.
LOL! Let me guess, you've got the manual in your trunk. FYI: I "grew up" Christian as well. Bible school and all that. Now what?
I understand that you're trying to get Jon off the hook by claiming that his Christianity cannot be cancelled or undermined by any hypocrisy---that his behavior cannot make him a hypocrite, because it's in the nature of a Christian to sin. But you've just granted his Christianity as a fact. If we don't grant it, there's actually something interesting to talk about. And if we don't grant it, it means we require some way to verify it, which is why I brought up the issue of verification.
That is the interesting implication of PeteyParker's post and what your response to him completely ignored. As you say,
---and this is in fact "a simplified, misguided way of seeing things." Because you have to assume Jon is a Christian before you can apply this defense to him. If you do, fine, but understand the assumption is glib. If Jon merely says he's a Christian, that's not enough for me. And if he's not a Christian, he's a particularly twisted hypocrite.
Anyway---have your say, and we'll move on. I don't want to trash the thread.
