Tom J. The church includes Christian parents. When did dad and mom teach their child that cohabitating is sinful and the adverse consequences associated with it? When did they teach the sixth commandment and its meaning from the Small Catechism? I don't know of any pastor who fails to catechize their catechumens in the Law of God, which includes the sixth commandment, as well as the sanctity of marriage. I agree that the challenge is great for Christian parents who themselves cohabitated before marriage, or were sexually active with their spouse before marriage, to explain to their children why it is not a good thing. The modeling of godly virtue by all of us, in matters of human sexuality, is what it is going to take, along with the teaching.
