[Before I start, as always, I apologize for any language errors. I am not a native English speaker, but I will try to write as correctly as possible].
I may be downvoted by liberal christians and non belivers, but i don't care :) Here we go.
Recently, I have often come across the view of liberal Christians that homosexuality is not a sin, not a mental problem or a perversion, and that homosexuals were born that way. They claim that the Bible does not condemn homosexuality at all, and we should give gay weddings in churches, appoint gay men as priests, church teachers, and preachers.
The Bible, however, leaves no doubt. And I am sure that quotations from the Bible were given many times on r / truechristianity, which clearly shows that homosexuality is condemned by God. Therefore, people with homosexual inclinations, if they believe in the biblical God and Christianity, should restrain themselves from homosexual acts, just like people addicted to alcohol or pornography, for example, should restrain themselves from their sin, even despite the powerful desire to get drunk or watch pornography.
I can present a broader scientific justification, but there is a lot of sexology and sex life of animals and human, so it should be read by mature people and I wouldn't like to behave improperly. If you want, I will upload this material.
TLR: To sum up - Homosexuality is obviously a sin (clearly written in the Bible), it is not genetically determined, it can be treated as a mental problem, perversion, it can be caused by various causes, primarily due to the influence of upbringing and shaping a person, or as a result of perversion.
