That is why a man leaves his father and mother and is united to his wife, and they become one flesh.
Leviticus 18 .22
You shall not lie with a male as with a woman; it is an abomination.
If a man lies with a male as with a woman, both of them have committed an abomination; they shall surely be put to death; their blood is upon them.
Because of this, God gave them over to shameful lusts. Even their women exchanged natural sexual relations for unnatural ones. In the same way the men also abandoned natural relations with women and were inflamed with lust for one another. Men committed shameful acts with other men, and received in themselves the due penalty for their error.
Furthermore, just as they did not think it worthwhile to retain the knowledge of God, so God gave them over to a depraved mind, so that they do what ought not to be done.
1 Corinthians 6:9-10
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. (1 Corinthians 6:9-10)
Some Pharisees came to him to test him. They asked, “Is it lawful for a man to divorce his wife for any and every reason?”
“Haven’t you read,” he replied, “that at the beginning the Creator ‘made them male and female’ and said, ‘For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh?' So they are no longer two, but one. Therefore what God has joined together, let man not separate.”
In a similar way, Sodom and Gomorrah and the surrounding towns gave themselves up to sexual immorality and perversion. They serve as an example of those who suffer the punishment of eternal fire.
1 Timothy 1:8-10
Here Paul writes:
Few thoughts about the theme:
Homosexual sin is serious and real.
Homosexual desire is not what God originally intended.
Homosexual sin is not unique.
Homosexual sin is not inescapable.
Jesus wasn't silent on homosexuality.
Some claim Jesus never said anything about homosexuality and therefore is neutral on the topic. Not true. Jesus was unequivocal in saying that to understand marriage and the sexual union, we must go back to the beginning and see how God created humanity and to what end. (See Matthew 19 and Mark 10.) Jesus holds up the creation story in Genesis not as a quaint Sunday school lesson, but as authoritative — reminding us that God created each of us male and female, each for the other. And the sexual union that God created and ordains is for husband and wife to come together in physical union, one flesh.
