Religion? Sort of. A lot of religious are just legalized cults (just look at Scientology) and exist only to control the masses, while barely teaching people about legit morals and ethics.
The real question is spirituality because it is something a lot of people are lacking and it does help build character and principals. Then again, fuck that up and you'll end up like a hippe, a diddler priest or Charles Manson.
why I find The Last Church to be such a good short story is because it tackles the issue of religion and secularism presents both the good and the bad of both.
