I think maybe the way I described Sean Hannity made it seem like churches are equally boisterous. They're not. But this overall message is there, I would argue, the vast majority of the time.
They can be throwaway lines, discussion of current events, discussions of the devil - but they're ever-present, even when subtle.
The implication with the devil is that the Devil has influence and hold over non-believers who don't have the protection of Christ. The implication with negative current events (from a school shooting, to poverty, to crime) is that REAL Christians don't behave this way and that the spiraling immorality of society is due, in part, to the taking of Christianity away from public life.
This isn't surprising by the way. The stories of Sodom and Gomorrah, Noah's Ark, Moses' exodus and even Jesus' salvation are reinforced with the idea that the unbelievers are given earthly and spiritual torment - AND THAT THEY DESERVE IT.
The implication of "we are better, and we have to strive to keep being better than THEM" is always there. (And it's not just Christianity by the way, it's a consistent calling card of most organized religious services).
The common general framework (if I could be overly generalistic) is:
- Mention a Bible passage or current event you're going to focus on
- Talk about examples (with the implication that this is how non-Christians behave)
- Talk about some in the parish may be behaving this way too, and try to be better.
But whether the audience member actually tries to be better or not, after repeated yearly sermons they leave with the general sense that the outside world is so immoral, so fucked up, and so in line with what the Devil wants from humanity.
