Blessing of same-sex unions in Christian churches

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 different sexes. These disagreements are primarily centred 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 numerous 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.
