What is Moral Decay in Religion?

I think that this question can be answered in two ways. One is the moral decay of a, individual religious person. One who rejects that which one had to go the way of the world and adopt its ways. Or where the Religion itself with all of its members turn away from their beliefs and go the way of the world moral decay takes over.

The second is the religions view of the moral decay of the world in general as apposed to its own righteous beliefs and righteous actions.
