Rome was at its peak during the pagan times; after they adopted Christianity things went downhill. Of course, correlation does not equal causation, but I don't see how Christians have any valid claim to moral righteousness. If any one thing could be pointed to for Rome's collapse, it's probably just corruption, which can happen to any society, and is not at all the same as "moral decay".
