Why was Christ so compassionate towards sexual sinners, especially women? Think of the woman caught in adultery. Think of the prostitute who wept at his feet.

The Church's basic moral principle regarding reproductive technologies is this: if a given technology assists the marital embrace in achieving its natural end, it can be morally acceptable, even praiseworthy. However, if it replaces the marital embrace as the means by which the child is conceived, it's not in keeping with God's design.
Brace yourself! If we take in what the Holy Father is saying in his Theology of the Body, we will never view ourselves, view others, view the Church, the Sacraments, grace, God, heaven, marriage, the celibate vocation...we will never view the world the same way again.
