The announcement that PrinceCharles is at last going to marry CamillaParkerBowles, his mistress, has prompted Cardinal KeithO’Brien of Scotland to renew an attack on the early 18th-century law that bars Catholics from the British throne. O’Brien did, however, congratulate Charles and Parker Bowles on their upcoming civil ceremony at Windsor Castle on April 8. Following the ceremony, the archbishop of Canterbury, RowanWilliams, will preside at a service of prayer and dedication for the couple. Williams said the arrangements “are consistent with Church of England guidelines concerning remarriage.” Because Parker Bowles is a divorcée whose husband is still alive, the Church of England would not sanction a church wedding. The prince, as king, would be the titular head of the church.
