Mr. Bogner asks a question below that I fear I do not have the expertise to address properly, but which I feel should be addressed, and so I place it here.
It also reminds me of Catholicism's approach to homosexual clergy - we all know there is a fair number of homosexual priests, but as long as they are celibate then it seems our bishops don't really pay much attention to them. If homosexuality is wrong, then isn't it wrong whether someone is celibate or not? Or is it? I don't have that figured out, not even close to it.
I venture into this area with trepidation, but I am certain that there are many more studied than I am who can correct my understanding of Church teaching. The church teaches that the inclination to homosexuality is intrinsically disordered but not in itself sinful. Just as the inclination to polygamy and promiscuity is gravely disordered, if it is not acted upon, it is not sinful. Homosexuality is not a sin. Being a homosexual is not a sin. Engaging in homosexual acts either physically or, as with heterosexual acts, entertaining thoughts and encouraging them, is sinful. A chaste homosexual is not committing a sin. He is defying no commandment and no law. Just as a person inclined to theft commits no sin so long as he takes nothing belonging to another. To be attracted to something is not in itself sinful--acting on that attraction can be so.
That's how I understand it, and I admit that it is very crude and not terribly nuanced. But the reason bishops care little if a person is a homosexual is that Priests are called to live a chaste life. I introduce this word because often we use celibate, which technically means only unmarried to mean chaste which refers to conduct. It is entirely possible to be celibate and unchaste and uncelibate but chaste. In the Carmelite Order we make promises of "chastity according to station in life." That is a married person is chaste when faithful to his or her spouse. A celibate person is chaste when he or she refrains from indulging the sexual impulse. A chaste, celibate homosexual should present no more problem for a bishop than a chaste, celibate heterosexual. There are theories and expositors to the contrary, but I will not argue that as I am on even shakier ground than this initial discussion. And I do invite those better informed, more aware, or more skillful in conveying proper Church teaching to jump in and help us all understand better exactly what the Church does teach.
