I wondered that myself. But in reading the article, I'm not so sure they got it right. He apparently lived for seven years in a monastic community and has some continuing ties, but that doesn't make one a monk. There is no mention of tonsure.
Which makes me wonder - sorry for the off-topic question. But it is my understanding that a monastic may not "quit" being a monastic? Unless perhaps in some very extreme circumstance that I am unable to imagine that the abbot (or would a bishop be necessary?) to bless?
I thought vows of monasticism were just that - vows - and could not be broken? Which I am given to understand the Abbott/Abbess is careful to ensure one is prepared to remain for life before tonsure?
Just curious.
