Glad you brought this one up, because I honestly think that the CofE is doing its utmost to modernise, without alienating it's conservative wing, and this is literally the best they could come up with.
The Bible condemns homosexuality, and I believe it states that gays should be stoned (and not in the 'Pete Doherty/Amy Winehouse way').
This obviously doesn't fit in with who we are in the 21st century, but a neat 'get out clause' is for the church to say - "Okay, you're gay - you can be a bishop...but just don't do the sex stuff".
In that way, they're actually complying with the written word of the Lord, in that, the Bible doesn't say that you cannot be a man and fancy David Beckham, Tom Hardy or Jason Statham. It just says that if you do, and you sleep with them, then you're an abomination.
