The Bishops are being pastoral again

So, the Anglican bishops chose St Valentine's day to have another go at gays in the church. In what they refer to as a 'pastoral statement' they state that those in same sex marriages can't be ordained and those gay clergy already serving can't enter into same sex marriages. Alright, we know they've got form in this area, but seeing as its now law, wouldn't you have thought the 'established' church (ie the denomination that's headed by the Queen) would accept the law as passed by parliament? Are the bishops so far removed from reality that they believe they can issue a pronouncement from on high that the rest of society will meekly accept?
And they wonder why their pews are getting emptier.
