Being "in" a religion and actually believing its doctrines are two different things. I have little doubt that there are probably many leaders in the major religions who are actually agnostics and simply go thru the motions of being faithful to whatever ritual is asked of them.
This is possible because most religions put forth some effort to help people in some organized way - whether soup kitchens, public charities, hospitals or the like. It gives people who are zealous - but privately heterodox - a chance to be supportive.
Sadly, this will never be the case with the "truth". I sometimes think I could still be involved in the organization if they really cared about people. ....... and that will never happen.
