Most of the stuff about homosexuality comes from Lev. As does the prohibition about eating shrimp and pork. People learned that properly prepared shrimp and pork do not kill and Lev was found to be false. People eventually will learn that gays being married or sharing other contractual arrangements will not kill us either and more of Lev. will be jettisoned.
Peace
False.
Romans 1:25-28, “They exchanged the truth of God for a lie and revered and worshiped the creature rather than the Creator, Who is blessed forever. Amen. 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. And since they did not see fit to acknowledge God, God handed them over to their undiscerning mind to do what is improper.”
1 Corinthians 6:9-10, “Do you not know that the unjust will not inherit the kingdom of God? Do not be deceived; neither fornicators nor idolaters nor adulterers nor boy prostitutes nor sodomites nor thieves nor the greedy nor drunkards nor slanderers nor robbers will inherit the kingdom of God.”
1 Timothy 1:8-11, “We know that the law is good, provided that one uses it as law, with the understanding that law is meant not for a righteous person but for the lawless and unruly, the godless and sinful, the unholy and profane, those who kill their fathers or mothers, murderers, the unchaste, sodomites, kidnappers, liars, perjurers, and whatever else is opposed to sound teaching, according to the glorious gospel of the blessed God, with which I have been entrusted.”
Also see Genesis 19:1-29, which is too long to post here. It is the story of how the men of Sodom demanded Lot send out the angels of the Lord, who appeared in the guise of men, to have relations with them, and how God destroyed the towns of Sodom and Gomorrah for their sinfulness.
Therefore, the Biblical condemnation of homosexual intimacy is not only, or even mainly, in Leviticus. Also, being that God has destroyed cultures for this reason (including pagan Rome), and not just Sodom and Gomorrah, we can’t be sure that gay marriage won’t kill us.
