By Hays' reasoning, penetrating a rectum with a penis is a violation of how God meant humans to function. However, penetrating a human body with a sword, a common way to kill people in biblical times, is acceptable. Apparently human bodies were designed to be penetrated by metal implements, but not by flesh.
The Catholic Church standing in "solidarity" with members of the LGBT community while condemning their behavior as "sinful" is a little like attempting to stand with two feet in one shoe. "Love the sinner, hate the sin" sounds really high-minded until you realize the only sin committed was being born different.
First, if you are a homosexual or feel that inclination, keep yourself pure. If you are unmarried, you should practice abstinence from all sexual activity. I know this is difficult, but really what God is asking you to do is pretty much the same thing that he requires of all single people. That means not only keeping your body pure, but especially your mind. Just as heterosexual men should avoid pornography and fantasizing, you, too, need to keep your thought-life clean. Resist the temptation to rationalize sin by saying, “God made me this way.” God has made it very clear that He does not want you to indulge your desires, but to honor Him by keeping your mind and body pure. Finally, seek professional Christian counseling. With time and effort, you can come to enjoy normal, heterosexual relations with your spouse. There is hope.
In addition to these physical problems, sexually transmitted diseases are rampant among the homosexual population. 75% of homosexual men carry one or more sexually transmitted diseases, wholly apart from AIDS. These include all sorts of non-viral infections like gonorrhea, syphilis, bacterial infections, and parasites. Also common among homosexuals are viral infections like herpes and hepatitis B (which afflicts 65% of homosexual men), both of which are incurable, as well as hepatitis A and anal warts, which afflict 40% of homosexual men. And I haven’t even included AIDS. Perhaps the most shocking and frightening statistic is that, leaving aside those who die from AIDS, the life expectancy for a homosexual male is about 45 years of age. That compares to a life expectancy of around 70 for men in general. If you include those who die of AIDS, which now infects 30% of homosexual men, the life expectancy drops to 39 years of age.So I think a very good case can be made out on the basis of generally accepted moral principles that homosexual behavior is wrong. It is horribly self-destructive and injurious to another person. Thus, wholly apart from the Bible’s prohibition, there are sound, sensible reasons to regard homosexual activity as wrong.
