Religion

You do need to be a decent public speaker, of course, but there are classes for that. You need some stuff to say, but every pastor with an Internet account posts his or her sermons, so you can learn from those. You'll need to memorize some Bible verses, too, but you don't actually have to be familiar with the whole thing. You can get by with a couple of the Gospels and a couple of Paul's letters. I recommend Matthew and John for the Gospels and the letters to the Romans and Corinthians. They're the most familiar, so what you say from those books will ring a bell with your audience.

The rest you can pick up from popular religious websites. Once you get through the first year, you'll be all set, really.

It's easy to learn the jargon. It's everywhere.

Now, mind you, not every start-up church prospers. If you want to succeed, you have to tell your audience what it wants and expects to hear, and tell some good stories to illustrate your points. Again, you can steal those stories from all of those church websites. The pastors at those stole them from someone else, too.

There are tons of tax benefits, of course, including your housing costs, etc. The IRS will pretty much leave you alone, because that's what they've been told to do.

Good luck with your grifting!
