Q. Are homosexuals born gay?
A. There is much controversy about whether homosexuals are born gay, choose it or something in between. At the moment the cause is not certain. However, what we do know is that practicing homosexual intercourse, oral sex, etc. is gravely sinful and disordered.
CATECHISM OF THE CATHOLIC CHURCH
Chastity and homosexuality
2357 Homosexuality refers to relations between men or between women who experience an exclusive or predominant sexual attraction toward persons of the same sex. It has taken a great variety of forms through the centuries and in different cultures. Its psychological genesis remains largely unexplained. Basing itself on Sacred Scripture, which presents homosexual acts as acts of grave depravity,141 tradition has always declared that “homosexual acts are intrinsically disordered.”142 They are contrary to the natural law. They close the sexual act to the gift of life. They do not proceed from a genuine affective and sexual complementarity. Under no circumstances can they be approved.
2358 The number of men and women who have deep-seated homosexual tendencies is not negligible. This inclination, which is objectively disordered, constitutes for most of them a trial. They must be accepted with respect, compassion, and sensitivity. Every sign of unjust discrimination in their regard should be avoided. These persons are called to fulfill God’s will in their lives and, if they are Christians, to unite to the sacrifice of the Lord’s Cross the difficulties they may encounter from their condition.
2359 Homosexual persons are called to chastity. By the virtues of self-mastery that teach them inner freedom, at times by the support of disinterested friendship, by prayer and sacramental grace, they can and should gradually and resolutely approach Christian perfection.
This teaching of the Catholic Church derives its authority from Sacred Scripture:
You shall not lie with a male as one lies with a female; it is an abomination.
13‘(A)If there is a man who lies with a male as those who lie with a woman, both of them have committed a detestable act; they shall surely be put to death. Their bloodguiltiness is upon them.
Deuteronomy 23:18 18You shall not bring the hire of a harlot or the price of a dog (a sodomite) into the house of the Lord your God as payment of a vow, for both of these are an abomination to the Lord your God.
27 and in the same way also the men abandoned the natural function of the woman and burned in their desire toward one another, men with men committing indecent acts and receiving in their own persons the due penalty of their error.
9 Or do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived; neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor homosexuals, 10 nor thieves, nor the covetous, nor drunkards, nor revilers, nor swindlers, will inherit the kingdom of God.
We know that the law is good when used correctly. 9 For the law was not intended for people who do what is right. It is for people who are lawless and rebellious, who are ungodly and sinful, who consider nothing sacred and defile what is holy, who kill their father or mother or commit other murders. 10 The law is for people who are sexually immoral, or who practice homosexuality, or are slave traders, liars, promise breakers, or who do anything else that contradicts the wholesome teaching 11 that comes from the glorious Good News entrusted to me by our blessed God.
By this it is established that the PRACTICE of homosexuality is gravely sinful, an abomination and detestable to God. HOWEVER, THE ORIENTATION IS NOT sinful. So, whether the human person is born a homosexual, or wounded in such a way that he becomes oriented towards homosexuality, or even out of some inner rebellion or rage actually makes a conscience choice, IT DOES NOT MATTER!
HOMOSEXUAL SEX IS A GRAVE SIN!
A person who finds himself/herself attracted to members of the same sex must exercise self mastery and abstain from indulging in this sin throughout his/her whole life. The suffering will purify the soul. This self denial is absolutely no different than many heterosexuals who find it extremely difficult to abstain from sex before marriage or even after marriage to remain faithful. They can often seem to be under as much compulsion to sin in this way as the homosexual. Both must deny themselves. The same can be said for those attracted sexually to children, rape, group sex, etc.
Whatever our inclination, we may find we are all born with certain proclivities to sin in different ways, we must overcome these with the help of God’s Grace and the sacraments, in order to grow in holiness. But God loves each and every one. Our eternal souls were created and infused into our bodies by our Heavenly Father. He wants every human person to join Him in Heaven after our time of testing in this life. So, take up your cross and follow Him. For what does it matter if you gain the whole world but lose your soul?
