God's condemnation of homosexuality is abundantly clear--He opposes it in every age.
- In the patriarchs (Genesis 19:1-28)
- In the Law of Moses (Leviticus 18:22; 20:13)
- In the Prophets (Ezekiel 16:46-50)
- In the New Testament (Romans 1:18-27; 1 Corinthians 6:9-10; Jude 7-8)
The letter "Philemon" deals with a run away slave by that name, who got saved through Paul's evangelism. Instead of keeping Philemon with him (thus "social justice"), Paul did the right thing and sent him back with instructions to his master to treat him as fellow heir of Christ and to forgive Philemon of anything wrong he caused or any debt he incurred (Paul was willing to have all if charged to his account).
So neither in regard to slavery or homosexuality, does Scripture demand social justice (of course today's view of social justice isn't justice but vengeance, homofascism, and acceptance of such sin).
