If a person doesn't believe in the virgin birth they shouldn't be clergy I guess. But I suspect that very few denominations would have adequate clergy if every single tenet of their denomination had to believed heart and soul by those who are otherwise Christian. It's a difficult question and I doubt that many could pass the test in thier own minds. Better to live a lie until you can make other arrangements I suppose.
It is no surprise that the anglicans beleive that way.The anglican/episcopal church has gone too far from their traditional beliefs. Queers and women as priests. No more book of common prayer,pander to every leftist idea that comes along.
