It seems to me that, having recognised the validity of the ministry of women in the role of priest years and years and years ago, it made no theological sense at all to deny to us the validity of their ministry as bishops. I'm glad the church is gradually getting a clue.
Now all we need to do is grant parishes who don't want to be overseen by a male bishop the opportunity to opt out and be overseen by a female bishop instead. That would be a suitable concession by those who demanded the opposite "suitable" concession before they grudgingly assented to this measure.
Oh, wait, I'm being mean-spirited. Stop that.
Next stop, recognising that not all people who offer themselves for ordained ministry are exclusively heterosexual. How long, do we think, before that happens?
