According to the Catholic Church, sexual intimacy between a man and a woman is the normal method of male and female bonding (emotionally and physically) because it corresponds to the design of our bodies and because it is the normal means by which offspring are created. If God had intended the human race to be fulfilled with both heterosexual and homosexual marriages, He would have designed our bodies to allow reproduction through both means and made both means of sexual intercourse healthy and natural.
Homosexual anal intercourse carries a high risk of disease, which is recognized in the Holy Scriptures, where gay men are said to receive in their bodies the due penalty for their sins. The Holy Bible clearly tells us in 1 Corinthians, Chapter 6, Verses 9 and 10: “Or do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived neither the sexually immoral, nor idolaters, nor adulterers, nor men who practice homosexuality, nor thieves, nor the greedy, nor drunkards, nor revilers, nor swindlers will inherit the kingdom of God.” God will not honour a sinful marriage between two homosexuals or lesbians.
Leviticus, Chapter 18, Verse 22 also tells us, “Do not practice homosexuality, having sex with another man as with a woman. It is a detestable sin.” Leviticus, Chapter 20, Verse 13 again says,. “If a man practices homosexuality having sex with another man as with a woman, both men have committed a detestable act. They must both be put to death, for they are guilty of capital offense.” The body is the temple of the Holy Spirit and one must not misuse it for any wrong purpose.
Remember, God destroyed the twin cities of Sodom and Gomorrah (Genesis, Chapter 19) because the men in those cities were filled with lust and were gays (homosexuals). I also quote Romans, Chapter 1, Verse 27: “Men committed shameless acts with men and received their due penalty for their error.”
