As a Brit (by nationality if not ancestry) I can honestly say that hardly anybody here seems to care what Charles and Camilla do (that's camel in Romanian, also, by the way!). It's clear that Charles is interested in Orthodoxy, his father had to give up Orthodoxy to marry the Queen (but still crosses himself like we do in public) and his grandmother became a nun after his grandfather's death. It's about time that the Church of England was disestablished. This would be good for the royal family because they could choose whichever religion they wanted, good for the state (I would argue there's no place for an established church in a state like modern Britain), good for the Church of England because they would no longer have to put up with intereference from parliament, and good for all the other churches, including us Orthodox. If this marriage starts people thinking in that direction then it will be for the good.
What Crucifer said is true. Charles and Camilla are going to have a civil wedding, but this is to be followed by a service of blessing by the Church of England (in St. George's chapel in Windsor Castle). That strikes me as somewhat hypocritical - their wedding clearly not being good enough for the church, but they'll bless it anyway. I don't suppose I should be surprised, though. This is far from the first time I've seen hypocrisy in the Church of England.
