” the majority if Christian churches fully support homosexuality and gay marriage, many have homosexual clergy and youth workers, and some even living with their partners “
Uh, NO.
Two questions: Where do you live and is the Christian world allowed to send missionaries there?
Yes Methodist, Episcopalian, and others, not Southern Baptist.
Wrong! Some "mainline" Protestant churches have become apostate and have accepted sin in their ranks - see Episcopal, ELCA, PCA, United Methodist, et al. But those denominations do not make up the "majority" of Christian churches.
1. Southern Baptist Convention: 16.2 million members
2. The United Methodist Church: 7.8 million members
3. The Church of God in Christ: 5.5 million members
4. National Baptist Convention: 5.0 million members
5. Evangelical Lutheran Church, U.S.A.: 4.5 million members
6. National Baptist Convention of America: 3.5 million members
7. Assemblies of God: 2.9 million members
8. Presbyterian Church (U.S.A.): 2.8 million members
9. African Methodist Episcopal Church: 2.5 million members
10. National Missionary Baptist Convention of America: 2.5 million members
11. The Lutheran Church-Missouri Synod (LCMS): 2.3 million members
12. The Episcopal Church: 2.0 million members
13. Churches of Christ: 1.6 million members
14. Pentecostal Assemblies of the World: 1.5 million members
15. The African Methodist Episcopal Zion Church: 1.4 million members
And the "mainline" denominations that have embraced homosexuality have been declining in membership, while those that hold to the Scriptural standards on issues of sexuality have been growing. There has been a big growth in "non-denominational" evangelical churches.
No Christian Church supports Homosexuality, just like no Muslim is moderate. Its a scripture thingie.
