Matthew 7:21-23 pretty much covers the false prophets like Falwell, Swaggart, Phelps and Wildmon:
21: Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
22: Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?
23: And then will I profess unto them, I never knew you: depart from me, ye that work iniquity. Those guys use the Bible as a club, beating up those who do things they don't like. You think ANY of this shit is about Jesus? It's about dicksizing. All of it. Falwell wants to make everyone bend to his will.
Phelps is a special case: he claims to be a Christian, but his entire theological reason for being--Leviticus 18:22--is out of the Old Testament. Now go to
http://www.commandmentsofyhwh.org/Leviticus/leviticus18.htm and read all of Leviticus 18. Please note that it contains eighteen sexual proscriptions, all of which fall into two groups: sex that produces no children (Lev. 18:20-23; I put 18:20--don't sleep with another man's wife--in here because it was okay to kill a guy who screwed your wife back then), and sex that produces inbred children (Lev. 18:6-19). The infant mortality rate was around 95 percent back then, so healthy pregnancies were critical and avoiding non-pregnancy-causing sex even more so. (If you read the whole Book of Leviticus, you can see it's really a survival manual for a civilization with no science. Take Leviticus 11:10--the one about not eating shellfish. Whoever wrote Leviticus probably noticed that people who ate shellfish sometimes died. Today we know about the red tide and paralytic shellfish poisoning, and it turns out that there are good-size dinoflagellate populations, which cause PSP, off the coast of Israel. But since they DIDN'T know about these things, but knew that eating clams sometimes killed you, they just put clam-eating down as an offense to God and had done with it.
But yeah, we've got false prophets floating around and Falwell's about as fake as they get.
