St. Alphonsus Liguori's Moral Theology has long been praised and held in the highest regard by the Church, covering every moral question of his day. This first ever English translation features book 4 of the Theologia Moralis, on The first through sixth commandments. These will cover topics as broad as the sin of divination, worshiping demons, blasphemy, oaths, vows, and when they are binding; when you must go to Mass and abstain from work, as well as considerations on the fourth commandment in regard to obedience, the fifth in terms of murder, just war and abortion, and in the 6th, adultery and the various sins against chastity.
