I’ve commented on this before, in Christianity, to have an incline to homosexuality is not a sin, but the church demands abstinence form homosexual practices, because that is a sin. I believe you that there can be a homosexual bishop in a Christian church, but it would a repented, abstinent, transformed individual, in fact churches are full of repentant sinners seeking strength in in her. You cannot be a Christian and a practicing homosexual and be Christian, there are some gay’s congregation that called themselves Christians, that is only on their minds, there is no such thing as a unrepented gay Christian. The church has a command to call all people to repentance, that involves a change, it is also a command to judge and correct in order to guide people to the kingdom that the Lord went to prepare for those that obey, that’s what Christian beliefs are, if you don’t obey you are not a Christian, acceptance by a congregation does not make him a Christian, as I said Christianity is not an all welcoming religion, it call all to repentance, it does not accept unrepentance of sin. There is always the argument that excommunication of unrepented sinner is unloving, but the truth is that what is unloving is to see people in a path that leads to perdition and not do anything to get them off it.
