Do you incorporate faith/religion in the Sims?

@Hermitgirl I love that you made a cult. I would have never thought of that, but that's an awesome idea!

I don't really incorporate religion other than having marriages or funerals in a religious building sometimes. It could be interesting to do, especially if I researched the various religions of all the City Living sims, but I already have so many things I want to accomplish in a sim's life that I'm too lazy to add that in, too.
