I have yet to meet a Christian who doesn't regularly practice at least one of the 7 deadly sins.

In the modern age, just Greedy, Envy and Wrath are already common amongst the vast majority of Christians - I mean, if you want to punish immigrants becuase you think that "they're taking our jobs" that's already Greed and Wrath and possibly also Envy.

Then even the most pious religious people are generally Prideful, at the very least on how close to the Lord they thing they are and how superior their own moral and ways are.

Sloth and Gluthony also tend to be very common - you certainly don't get overweight "epidemics" in a country without tons of people doing very little when they could do more (say, riding their car everywhere) and eating far beyond what they need.

If there's ever a Rapture, nobody will notice because only a handful of people - most of whom eremits living separate from the rest of the World - dissapears.
