Not all moral issues have the same moral weight as abortion and euthanasia. There may be legitimate diversity of opinion even among Catholics about waging war and applying the death penalty, but not... with regard to abortion and euthanasia.
Pope Benedict XVIWhen human affairs are so ordered that there is no recognition of God, there is a belittling of man. That is why, in the final analysis, worship and law cannot be completely separated from each other. God has a right to a response from man, to man himself, and where that right of God totally disappears, the order of law among men is dissolved, because there is no cornerstone to keep the whole structure together.
Pope Benedict XVITo have Christian hope means to know about evil and yet to go to meet the future with confidence. The core of faith rests upon accepting being loved by God, and therefore to believe is to say Yes, not only to him, but to creation, to creatures, above all, to men, to try to see the image of God in each person and thereby to become a lover. That's not easy, but the basic Yes, the conviction that God has created men, that he stands behind them, that they aren't simply negative, gives love a reference point that enables it to ground hope on the basis of faith.
Pope Benedict XVIIn the pierced heart of the Crucified, God's own heart is opened up - here we see who God is and what he is like. Heaven is no longer locked up. God has stepped out of his hiddenness.
