text: I hate to tell you this but ALL mainstream Christian churches, including The RCC, are losing members.  Hand over fist.  The only two countries where is it gaining members is Africa and South America, in that order.  Also remember that lots of people call themselves Catholic, but do not participate in The RCC in any way.  Also remember that the number of atheists, agnostics and simply 'unchurched' are growing at a pretty good pace.  (Perhaps a surprise to you, the vast majority of atheists, agnostics and 'unchurched' are not immoral.)  Considering that an estimated 10% of the RC priests are homosexual (and most are celibate) and that around 10% are/have been pedophiles, church affiliation or no church affiliation does not have a lot to do with sinning and being virtuous.
