That's not what a good Catholic is...in my opinion.Far as I can figure, the sustaining idea would be that good Catholics will never engage in sex without accepting the possibility of pregnancy and the duties that come with it.
A good Catholic is a person who has protected sex. By using contraceptives.
A good Catholic doesn't do what the Pope tells them to do. If the Pope tells me to jump off a cliff, I won't do it.
The Church condemns usury too...but so many bankers are allowed into the church...Why would people insist on both adhering to a group with clear directives and make a point of not caring about those directives is a very proper question to ask.
