"I know of homosexual priests who live chastely. They recognize that they have a disorder, and they succeed in working around it ... Such priests deserve our respect.

On the other hand, there are homosexual priests who are "gays"—they have chosen to live the homosexual lifestyle. It is from the ranks of these priests that most (not all, admittedly) of the abuse cases have arisen. The priestly scandal has not been so much about priests abusing children as about homosexual priests acting out their homosexuality with teenagers and young adults ..... 

If the priesthood in this country were healthy, little or no harm would come from ordaining chaste homosexuals whose homosexuality is kept private. But we do not live in ordinary times. We live with a priesthood that has been damaged by "gay" homosexuality. Until the damage is repaired, we should operate conservatively."
