This article largely discusses presence of openly lesbian, gay, bisexual, and transgender and queer bishops in churches governed under episcopal polities. The existence of LGBTQ bishops in the Roman Catholic, Anglican, Lutheran and other traditions is a matter of historical record, though never, until recently, considered licit by any of the main Christian denominations. Homosexual activity was engaged in secretly. When it was made public, official response ranged from suspension of sacramental duties to laicization. The higher prominence given today to the presence of LGBTQ clergy, including bishops, in the life of the church reflects broader issues, both socially and ecclesiologically (see List of Christian denominational positions on homosexuality), concerning issues of social tolerance and the relationship between social change and doctrinal development. The issue has attracted greater attention in recent years following the development of the gay rights movement, and the increasing discussion within some Christian churches over the inclusion of gay clergy in senior positions.
