The United Methodist Church is standing by its teaching that gay marriage is not compatible with scripture.
This week, the denomination defrocked a Pennsylvania pastor for performing his son's same-sex wedding.
Rev. Frank Schaefer has led a congregation in the town of Lebanon, Pa., for more than a decade.
In 2007, he officiated the wedding of his gay son in Massachusetts, where same-sex unions are legal.
The Methodist Church allows gay and lesbian members, but homosexuality is viewed as incompatible with Christian teaching.
Schafer was given 30 days to reflect, repent and promise never to violate Church teaching on the issue again. When he refused, United Methodist officials revoked his ministerial license.
"When asked to surrender his credentials as required by the verdict he refused to do so," church spokesman John Coleman said. "Therefore, because of his decision, the board was compelled by the jury's decision to deem his credentials surrendered."
The pastor plans to appeal the church's ruling.
