Fr Z has had a letter too and includes it in the post: Bp. of Portsmouth deep sixes Q&A piece. The correspondent says that Bishop Hollis
... was genuinely unaware of the contents of the Q&A until the whole thing blew up in his face.
When I first saw this rumour yesterday, I emailed the Portsmouth Diocesan Press Officer asking for clarification. I'll pass on any response I receive.
I'll also pass on Fr Z's recommendation: if you wrote to Bishop Hollis complaining about this, it is a good idea to write again to thank him.
