I don’t find God’s prohibition of homosexual activity any harder to defend than I do the prohibition of any other sin. The problem I see is pointing out sexual behavior between two persons of the same sex, is omitting illicit sexual behavior between men and women, as being something lesser in importance. Why should gay men and lesbians refrain from sexual activity if we condone pre-marital, extra-marital and illicit sex within marriage, (yup just because you are married does not make anything you do in your bedroom legit). I’ve heard some of the most anti-gay bigots decry homosexuals, and homosexuality, yet they sleep around, are on their second or third wife, (or husband) engaged in pre-marital sex, etc. If we believe that sex is something sacred that we can only share in a legitimate manner when we are married, and (in the case of a married couple during their fertile years) that is open to cooperating with God in the formation of new life, then we should be condemning all behavior that does not conform to God’s plan.
It is far easier to live a life where we make compromises and excuses to hard situations. On a seemingly different subject, I have some friends who are willing to pray the rosary with me when they come to visit, or when I visit them. I also pray the rosary when I am walking my dogs, (sometimes I use a traditional rosary with beads, other times I use a penal or finger rosary.) All but one of these people will chat about anything under the sun when walking, but are afraid of praying the rosary in public even when we say the prayers in a lower tone of voice with few or no people around to hear or see us. Another “side effect” of praying the rosary when I walk my dogs, even when I’m feeling tired and my bones ache, I know that having set the example of being a Catholic, and I can’t ignore when my dogs leave a little gift on someone’s lawn, and I have to pick it up. I had one lady come out and yell at me one day, her neighbor yelled at her, “Don’t worry, I see him pray the rosary and pick up his dog’s poop all the time.” Since then when I go by the house the woman now runs out when she sees me waving her rosary at me and smiling. I do sometimes meet chatty neighbors, and note where I am on the rosary, put it away, have a conversation with them, and then pick up where I left off. I also smile and say hello to the local prostitutes and other people who are less “upstanding” members of society. They stop and pet the dogs, I stop and talk with them. Never once have the women offered their wares to me, but two have told me they where raised Catholic. I’ve offered to pray just one decade of the rosary with them as they pet the dogs. Both have done so, and both have told me they felt better afterward, have gone to confession, and no longer work as prostitutes. I did not “preach” to them about the moral teachings of the Church, I simply allowed them to join me in praying, as I would any Catholic friend who visits my house, and prays the rosary with me. (Nobody who visits is obliged to pray the rosary with me before they spend the night in my guest room, read here when the couch is unfolded *) If they don’t want to pray the rosary with me in the living room, I will pray is with the dogs as usual, or in my bedroom.) So someitmes, (to get back on track about Catholic Moral teaching) the best defense is not argument, but example.
* In keeping with the Moral teachings of the Church single males or married couples where both man and wife are present, (and kids in sleeping bags) are the only ones who get an inviation to sleep on the couch. Females or anyone else who may lead to scandal are given assistance in finding other lodgings.
