The Church of England now has numerous female vicars - in fact if they didn't many churches would have no vicar. The Church of Scotland has had female ministers for ages - almost all of the local churches here in East Lothian have female ministers.
The minister at St Mary's Parish Church in Haddington is a very capable woman - I don't think anyone would ever think she wasn't up to the job, and she is now Moderator of the church's Lothian Presbytery. The priest at the Haddington Episcopal church is also a woman, again very capable and has done a lot to turn that church around after a string of ineffectual incumbents and a falling congregation.
I think who makes a good minister/vicar/priest depends entirely on the individual. I've been to churches with very uninspiring ministers of both sexes, and vice versa.
I suppose the problem with having a female Pope would be that much of the RC church's doctrine seems to exclude women or put them in a subservient position. However, I like what I see of the new Pope so far - the main thing, IMHO, is that whoever is Pope should be a great person and priest, and do his/her best not to get bogged down in all the pomp and ceremony. So far Pope Francis seems determined to do that - good for him.
How on earth did we get on to this in the Mystery Corner?
