This happened because of sin. The sin might reveal that he is not even a true Christian. Imagine that. You can preach a lot of truth but if you do not live by it, you are not the real deal.
You can argue for and against alll those other things and I might agree with some of your arguments. But they are unrelated to this. I've seen people who were none of those things fall into the same sin trap (sexual sin is a biggie). You notice the famous people and tend to want to draw connections. But that's a red herring. This happens because of the unaddressed depravity in his own heart. It isn't because he is well-known, political, tele-evangelist, mega-church pastor, and all the rest. I don't agree with many of the man's religious teachings, but this happened only because of one thing: SIN!
Do you know how many pastors these days have a problem with pornography? If studies are true, a whole bunch of them have a problem with it and they come from all sorts of backgrounds and perspectives. The church has been corrupted by sin. We need to clean house. Even good doctrines are being manipulated to excuse sin, not just the bad ones. We are even using grace as an excuse for licentiousness. Our hearts have been corrupted and our consciences dulled. Those other things are symptoms of the sin disease.
Hey it is a good job, most preachers I know live in nice homes, have expense accounts, and don't have to punch a time clock. Lucrative position.
I was not making an excuse for sin. Sin stands on its own. I just think we have a lot of these teachers going around calling themselves "apostles", "annointed", "prophets", unchallenged by most evangelicals. And then when something like this happens, its suppose to be a black eye for all evangelicals.
One of the greatest truths preached by Christianity is the forgiveness of sins. If one claims to be a Christian and then doesn't forgive another's sins, then indeed that one is not much of a Christian.
That is why those who compiled the Creed put it in: "I believe in the foregiveness of sins." It is easy to forget unless we are reminded. And much harder to put into practice.
