Open and affirming

'''Open and Affirming ''' (ONA) is an official designation of congregations and other settings in the United Church of Christ (UCC) affirming the full inclusion of gays, lesbians, bisexuals and transgender persons (LGBT) in the church's life and ministry.

The Open and Affirming program is administered by the UCC Open and Affirming Coalition, which supports congregations and other church settings as they consider the adoption of an ONA "covenant" and maintains the official registry of ONA congregations and ministries. The Coalition encourages UCC congregations, campus ministries, seminaries, regional bodies and other settings of the church to engage their members in serious study of sexual orientation and gender identity and to declare publicly their full welcome and inclusion of LGBT people. With more than 1,200 congregations, the UCC's ONA program is the largest of several LGBT-welcoming church movements in U.S. and Canadian churches.
