Dr Barry Morgan said he would be willing to consecrate a gay bishop
The Archbishop of Wales says he would be willing to consecrate a gay bishop.
Barry Morgan spoke as the world's first openly gay bishop, whose ordination has caused a split in the Anglican church, is to preach at a church in London.
Bishop of New Hampshire Gene Robinson has been excluded from the Lambeth Conference of church leaders.
Dr Morgan said the consecration of a gay bishop would no problem to him, although it might be for his church, and he would "alert" fellow leaders.
He said: "If I thought that a person who had been nominated was an excellent candidate in every other way and that he was in a faithful relationship - for me personally that would not present a problem.
"But of course it might present a problem for my church and I would have to alert the electoral college to that," Dr Morgan added.
Bishop Robinson has been excluded from the Lambeth Conference, held every 10 years, but will be in Canterbury at the same time.
He is due to speak at St Mary's Church in Putney, west London, on Sunday.
Anglican conservatives set up a splinter movement earlier this month, in rejection of the acceptance of gay bishops.
Members of the Global Anglican Future Conference movement established the Fellowship of Confessing Anglicans.
Bishop Robinson publicly announced his sexuality in the 1980s and has since been in a 20-year relationship with his current partner.
