Plus, there is the fact that pastor or priest is the only job they are trained to do. Those that have a degree, usually have one in some sort of theology or Bible history - such degrees don't really have much cross-over to other areas. So, to support yourself and your family, you don't let on that you now think it is all bunk. You also have to factor in that, once the disbelief is made known, all those people who called him friend will turn on him faster than a rabid dog and force them out of both their home (since many churches provide housing for their pastors) and their job. It takes a lot of strength to be able to cut yourself off from your entire physical social network and safety net.
Indeed, indeed. To add to that, I'd be willing to bet both of my testicles that if a priest, rabbi, or imam, were just to come out and say, this is all hogwash and god is make believe, there would be some kind of uproar. Maybe rather than be the one who struck that match that ignited that powder keg, he decided to stifle his own beliefs for the sake of others. The needs of the many outweigh, the needs of the few, or the one.
Sometimes things happen in life that people don't like. Sometimes people do things that people don't like. Sometime people make judgment calls that don't pan out. When this happens, it's real easy to have the arm chair quarterback, hindsight is 20/20 mentality and condemn them for doing so. As I said, there are times in life where untruthfulness is less painful than the truth and is the most viable option at the time. How many parents are going to tell their 4 year old that mommy/daddy isn't going to get better, and is going to die, even though they know that is the outcome until they absolutely have to?
I've read some of the stories of pastors who have lost their faith. Many of them do wind up staying, at least for a time, because they have no other options. It takes time to get prepared for another, secular job and to save up the money to move to new living quarters. Religious leaders who have let it be known they have lost their faith, have received death threats against them and their families.
It is easy to sit back and judge. However, these people are leaving the only life they have known for years. It is not done easily or lightly. If keeping a job that provides food, clothing, and shelter for me and my family requires faking it for a time, then so be it. Heck, it is not like the flock is living in the light of truth as it is.
