Thank you so very much for your comprehensive and interesting reply which I will consider carefully.
Over 15 years ago, I went on holiday to Glastonbury with a friend. We both attended a quiet, midweek Anglican Eucharist celebrated by a very elderly priest. One couldn't fail to notice his "true personhood": a sort of ordinariness which seemed exceptionally holy, pure and loving. I mentioned this to my friend afterwards, and she told me that as soon as she saw him, she noticed that he was suffused with a gentle, golden light. She also told me that she used to know an elderly Anglican priest in Surrey who demonstrated exactly the same personal qualities and had the same golden light within and around him. That was my reason for asking the question!
