David Stancliffe, the bishop of Salisbury and the church's principal authority on the rules of worship, said Prince Charles and his bride to be, Camilla Parker Bowles, must do more than repeat the words of a confession during the church service, the Sunday Times reported.
"The Prince of Wales and Mrs. Parker Bowles will be taking part in prayers of penitence at the service of prayer and dedication following their civil marriage," Stancliffe said in a statement. "Preparation for the formal expression of such prayers includes the making good of any hurts, the restoration of relationships and serious attention being paid to the relationships fractured or damaged by misconduct."
The apology would have to be offered in advance of the April 8 church service in St. George's Chapel in Windsor.
Other divorced men and women, who have committed adultery have been expected to apologize directly to the injured party in person or by a letter.
"This is a private matter," said a statement from the prince. "We would not comment."
