Here in the U.S., governmental antipathy toward religion and particular the Catholic Church is a growing threat. Catholic organizations are already being prevented from providing adoption services and you can bet your favorite pair of skinny jeans that gay marriage laws will eventually culminate in discrimination charges for any religious organization that refuses to go along.
All these things erode our religious liberty. But the governmental death blow aimed at the heart of the Church is to destroy the seal of confession. If you think this could never happen, think again. It may be happening right now in Ireland.
