Scripture is clear:
Leviticus 18:22
22 " 'Do not have sexual relations with a man as one does with a woman; that is detestable.
Romans 1:27
27 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.
Leviticus 20:13
13 " 'If a man has sexual relations with a man as one does with a woman, both of them have done what is detestable. They are to be put to death; their blood will be on their own heads.
1 Corinthians 6:9
9 Or do you not know that wrongdoers will not inherit the kingdom of God? Do not be deceived: Neither the sexually immoral nor idolaters nor adulterers nor men who have sex with men
1 Timothy 1:8-11
8 We know that the law is good if one uses it properly.
9 We also know that the law is made not for the righteous but for lawbreakers and rebels, the ungodly and sinful, the unholy and irreligious, for those who kill their fathers or mothers, for murderers,
10 for the sexually immoral, for those practicing homosexuality, for slave traders and liars and perjurersand for whatever else is contrary to the sound doctrine
Jude 1:7
7 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.
Mark 10:6-9
6 "But at the beginning of creation God 'made them male and female.'
7 'For this reason a man will leave his father and mother and be united to his wife,
8 and the two will become one flesh.'So they are no longer two, but one flesh.
9 Therefore what God has joined together, let no one separate."
1 Corinthians 7:2
2 But since sexual immorality is occurring, each man should have sexual relations with his own wife, and each woman with her own husband.
