Now, on the subject of gay marriage, please refer to the Holy Bible about homosexuality. 1 Corinthians 6:9-20 says,

‘Do you not know that the wicked will not inherit the kingdom of God? Do not be deceived: Neither the sexually immoral nor idolaters nor adulterers nor male prostitutes nor homosexual offenders nor thieves nor the greedy nor drunkards nor slanderers nor swindlers will inherit the kingdom of God. And that is what some of you were. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God.
“Everything is permissible for me”—but not everything is beneficial. “Everything is permissible for me”—but I will not be mastered by anything. “Food for the stomach and the stomach for food”—but God will destroy them both. The body is not meant for sexual immorality, but for the Lord, and the Lord for the body. By his power God raised the Lord from the dead, and he will raise us also. Do you not know that your bodies are members of Christ himself? Shall I then take the members of Christ and unite them with a prostitute? Never! Do you not know that he who unites himself with a prostitute is one with her in body? For it is said, “The two will become one flesh.”But he who unites himself with the Lord is one with him in spirit.
Flee from sexual immorality. All other sins a man commits are outside his body, but he who sins sexually sins against his own body. Do you not know that your body is a temple of the Holy Spirit, who is in you, whom you have received from God? You are not your own; you were bought at a price. Therefore honor God with your body.’

Blessings.
