The blessing or wedding of same-sex marriages and same-sex unions is an issue about which leaders of Christian churches are in ongoing disagreement. Traditionally, Christianity teaches that homosexual acts are sinful and that holy matrimony can only exist between two persons of the opposite sex. These disagreements are primarily centered on the interpretation of various scripture passages related to homosexuality, sacred tradition, and in some churches on varying understandings of homosexuality in terms of psychology, genetics and other scientific data. While various church bodies have widely varying practices and teachings, individual Christians of every major tradition are involved in practical (orthopraxy) discussions about how to respond to the issue.

What's more, God is not saying this to gay people. God's Word is this: For God so loved the world that He gave His only begotten Son that whosoever believeth in Him should not perish, but have everlasting life. (John 3:16, KJV). And that is the Good News for modern gays." The Biblic references to homosexuality were uttered in the context of promiscuous same-sex practices of Hellenistic cultures (Paul) and cultures surrounding the people of Israel (Deut).
