I am not in TEC (I'm in Australia) and - officially - in Australia our gay clergy are supposed to be celibate. But we also all know that that rule is honoured more in the breach, as they say. That is not a situation with which I'm entirely comfortable, not least because there's a significant lack of integrity in it, but I have worked closely with some of those clergy and have some insight into why the church behaves the way it does.
As best I understand it, there is a significant cultural shift going on, not just in terms of how we understand homosexuality, but also in terms of how we understand human development, sexuality more broadly, and so on. We've also seen the legacy of some very very damaged people who have struggled with homosexuality and, instead of being treated with compassion and grace by their churches, have been treated with condemnation and contempt.
So - in desiring to repent from that condemnation and contempt - and in wrestling with how we make sense of Scriptures written from a perspective on human development, social relations etc which is fundamentally different from our own in many ways, some people have concluded that what the Scriptures are talking about is not the question of people who have developed with same-sex attraction as their primary orientation (that in fact the ancient world would not have recognised what today we call "homosexuality" at all), nor are the relationships forbidden in Scriptures long-term, committed, monogamous, faithful relationships.
That is a highly debatable point, and I'm not putting it forward here as my own position, I'm just trying to present that point of view fairly.
So, if you take all of that as a package, when you're presented with a gay person who is, in every other way, an exemplary Christian, who either does not have a relationship and is celibate or who adheres to fidelity and monogamy in his/her romantic partnership, there is a case to be made that that person is no less fit for the ministry than a straight person in the same situation. If that makes sense?
But unless the priest in your local parish is gay, you can probably ignore the whole thing very easily.
