Q - Do you think sin is more prevalent nowadays than ever before? Co-habitation, abortion, pre-marital sex, empty pews. What has caused this on such a large scale?
A - Sin is a universal over time. If we look at the time of Jesus, there were just as many sins being committed then as now. Pagan temple prostitution, murder, unjust war, infanticide, etc. So, while our culture surely isn't one full of virtue I don't think that we are the worst thing that has ever been under the sun. In fact, in many parts of the world, Catholicism and other kinds of Christianity is spreading like wild-fire.
I have hope that the fruits of conversion, grace and in particular, Vatican II (read about it here and here) are coming now and in the future and the generation that will truly turn our culture back to Christ is here now.
