I think having a woman archbishop is fantastic but I do wonder if this post was always going to be filled by a woman and we were simply waiting for the last archbishop to resign/retire. The Anglican church is diminishing in the UK so I do wonder if this is maybe a large change in a conservative institution to try and save off falling interest in relgion.
The other major Abrahamic faiths Islam, Judaism as well as Catholicism all have patriarchal structures and yet maybe perversely are in my opinion more robust currently.
In also think that there are conservative elements within the Anglican church that will feel troubled by this decision and I wonder if this will become divisive?
