It is just a rumour from David Anderson but if Jeffrey John were to become Bishop of Bangor in the Church in Wales then it would be poetic justice. First of all, Jeffrey John would be rightly recognised. Secondly, it would be in Rowan Williams's own ex-Church, where he used to hold actively more progressive opinions himself on this matter. No one wants particular individuals to make religious-political points, so this should only be based on the talent of the man and the desire of clergy in that diocese and the Church in Wales bishops to have him, but that secured he should be appointed. Barry Morgan, Archbishop of Wales, and connected with the Modern Churchpeople's Union, has indicated he has no objection to consecrating a properly elected bishop. If he is, then let him be so consecrated.
Notice to GAFCON and its Primates' Council. Wales is to the west of most of England, and east of Ireland with some water in between. About a fifth speak Welsh and many more understand it as a secondary language from school. I suggest at least one Welsh speaking bishop for your new Province of the British Isles.
