HARRISBURG, Pennsylvania, Sept 16 (LSN) - The Pennsylvania Catholic Conference published a document Wednesday calling unmarried couples to refrain from living together until marriage.  Catholic World News reports that the document, entitled “Living Together: Questions and Answers Regarding Cohabitation and the Church’s Moral Teaching,” explained the Church’s teaching on chastity and why it leads to a better marriage relationship.  “The choice to live together outside a marriage is always wrong and sinful,” says the document. But remaining chaste will “strengthen your marriage, deepen your friendship, foster deeper intimacy and communion, build up your problem-solving and communications skills [and]  give your marriage a greater chance for success.”  For the whole document see:  http://www.pacatholic.org/bishops/cohab.htm
