In my first job out of school I worked in a office where the laziest guy there was a religious guy that spent most of his free time going to church "pie socials" and otherwise hanging around the church.
He eventually quit his job and somehow got a church of his own.
Another guy that I knew from scuba diving was a minister and was an attention whore. I'm not saying that they weren't believers, they were, but they mainly seemed to be into the attention, free housing, food, people fawning over them, etc.
It's easy to be traveling and eating all the time while "ministering", going to conferences, figuring out how to "grow" the congregation. Most of their friends are from the congregation so it's a pretty closed world.
