Simple -- they're at a MegaChurch near you.
But what they do, when, say, Ted Haggard gets high and engages in gay sex, is say... well, he wasn't really saved before. But this time (after the whole rededication / rebaptism) it'll stick -- pinky swear.
And that's really where I think a lot of my Protestant brothers are incorrect -- they focus too much on whether a person is "saved" and not what happens afterward. What MUST happen afterwards that the faith should bear fruit, otherwise, the faith is dead. (Those who keep the faith to the end...)
So what is that fruit? Corporal works of Mercy, becoming more Christ-like, always continuing to refine one's self, abandoning venial sin habits, etc. Those are the fruits of a faith that is alive and well.
tl;dr: Don't just be a pew sitter on Sunday morning because you like the coffee or the praise band (Prayer Bolt.. ) or want to feel like you're part of the club. "Oh hey, we're part of Faith Grace Meadow Church -- yeah, the one the size of a Wal-Mart superstore. Yeah, the praise band makes me feel happy, and the pastor just talks about what's in the Bible."
"Oh, I was thinking about trying Grace Faith Meadow, they say they teach just what's in the bible too"
"NO THEY ARE DIRTY HEATHENS!"
And so on, and so forth. The riff on the People's Front of Judea and the Judean People's Front from Life of Brian was intentional.
And while I'm wound up...
The segregation I see in the Protestant Community really bothers me. "Oh, we only send our kids to christian school (or homeschool)" -- meaning that there are fewer points of light in the public schools.
Or, "We only buy Christian media" -- fine, but then without Christian influence the culture rots faster.
It's time for Christians to stop segregating ourselves, and START FIGHTING THE CULTURE WAR. Start throwing some (metaphorical) punches at the culture.
