There is no such thing as “gay Christianity” , no more than there is a category of Christians called “gay Christians,” “immoral Christians,” “sodomite Christians,” “idolater Christians,” or “adulterer Christians”. As the apostle Paul makes perfectly clear in 1 Corinthians 6:9-11, especially verse 11, the Gospel of salvation in Jesus Christ is the power of God to spiritually transform from the inside out the hearts and lives of all the unrighteous members of Adam’s fallen race (equals all of us )–all whose sins have spiritually separated us from God (Isaiah 59:2; Romans 3:10, 23; Romans 1:16-17), including the sexually immoral, idolaters, adulterers, homosexuals, sodomites, drunkards, revilers, extortioners, etc,(see 1 Corinthians 6:9-10): “And such were some of you ; but you are washed, but you are sanctified , but you are justified in the name of the Lord Jesus , and by the Spirit of our God.” (verse 11). So please note, as was true in Paul’s day, that just as the Gospel was able to save/deliver any sinner, heterosexual or homosexual, from the corrupting power and bondage of all sin , including homosexuality, then, so it is able to do so today. As the Bible explicitly states: “Therefore if any man be in Christ, he is a new creation : old things are passed away; behold, all things are become new” (2 Cor. 5:17). “Any man” , of course, includes the homosexual , and to be “in Christ” means to be saved–to become a Christian or Spirit-regenerated, Spirit-adopted son and daughter of God through the life-changing power of the Spirit of God in the new birth and faith in Jesus Christ (John 1:12-13; Ephesians 2:1, 5; 8-9; Titus 3:5; Acts 16:14; etc.). God bless.
