Education is about asking questions, not being given answers. My Catholic education seems to be a good investment. It was from a time before St. John Paul started rooting out dissent (anyone who disagreed with him), before Evangelicum Vitae, when we were taught in ethics class that twinning meant that life did not begin at conception. It was only in the JPII era that the canard that a second soul was added to cover up the inconvenient truth. And you think doctrine does not change?
