Bagging Clerics is his first goal.

I think I might have to disagree with that. I think his first goal is to convince us he doesn't exist (although he may have already succeeded to some extent with our fellow man). Just like CS Lewis wrote in The Screwtape Letters, Satan's greatest achievement was convincing mankind he didn't exist.

I believe it is a line from “The Advocates Devil”, when Al Pacino relates to Keanu Reeves.
“The Greatest trick in the World is that the Devil convinced everyone that he doesn’t exist” By then you know he is satan.

Yep. I'm amazed at how many people believe there is no hell "because a loving God wouldn't send anyone to hell", blah, blah, blah.
