The Devil is able to trick normal masculine men into thinking and believing they are homosexual. Homosexuality is demonic; it is a perversion of human sexuality.

Although homosexuality has become a cancer in the Catholic Church -- and despite the many militant homosexuals within the clergy -- the teaching of the Catholic Church regarding homosexual sexual activity as morally disordered -- constituting grave sin and against the Natural Law which binds all human beings -- is unequivocal.

“All passions are dishonorable, for the soul is even more prejudiced and degraded by sin than is the body by disease; but the worst of all passions is lust between men… The sins against nature are more difficult and less rewarding, since true pleasure is only the one according to nature. But when God abandons a man, everything is turned upside down! Therefore, not only are their passions [of the homosexuals] Satanic, but their lives are diabolical… So I say to you that these are even worse than murderers, and that it would be better to die than to live in such dishonor. A murderer only separates the soul from the body, whereas these destroy the soul inside the body… There is nothing, absolutely nothing more mad or damaging than this perversity.
_ Saint John Chrysostom, Patriarch of Constantinople

Therefore, God handed them over to degrading passions. Their females exchanged natural relations for unnatural, and the males likewise gave up natural relations with females and burned with lust for one another. Males did shameful things with males and thus received in their own persons the due penalty for their perversity. (Romans 1:26-27)

The attraction is lust -- not love.
It is an evil spirit that causes one to feel lust for -- and become sexually aroused by -- another person of the same sex!

Homosexuality is sexual perversion;
it is human sexuality perverted by the devil!

It all begins with temptation. Many people are tempted with “same-sex” attraction. But temptation is to be resisted! So submit yourselves to God; resist the devil, and he will flee from you (James 4:7).

Evil increases insensibly, once it is given in to.

There is no question that sodomy (anal intercourse between two men) is “unnatural.” Sodomy is a perversion of human sexuality -- it is evil.

You shall not lie with a male as with a woman; such a thing is an abomination. If a man lies with a male as with a woman, they have committed an abomination… (Leviticus 18:22;20:13)

The “sin of the Sodomites” (homosexual sexual activity) is one of the sins that cry to heaven. (Catechism of the Catholic Church, 1867)

Then the LORD said, “Because the outcry against Sodom and Gomorrah is great and their sin (sodomy) so very grave, I will go down to see whether they have done altogether according to the outcry which has come to Me; and if not, I will know.”
Then the men (angels) said to Lot, “Have you any one else here? Sons-in-law, sons, daughters, or any one you have in the city, bring them out of the place; for we are about to destroy this place, because the outcry against its people has become great before the LORD, and the LORD has sent us to destroy it.” (Genesis 18:20-21;19:12-13)

“Have you not read that from the beginning the Creator ‘made them male and female’ and said, ‘For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh?’ So they are no longer two, but one flesh. Therefore, what God has joined together, no human being must separate.” (Matthew 19:4-6)

It is right for us to judge actions that are wrong and objectively sinful! We must hate sin. But it is wrong for us to judge people. We must love the sinner.

Q: Who decides what is wrong and
objectively sinful?
A: The Magisterium -- the Teaching Authority of
the Catholic Church, 
which consists of the Pope and the Bishops.
