ExcommunicationRoman Catholic AnswerI could be wrong, but I don't know of anyway to remove a person from the Catholic Church. If a person is a Catholic, then they remain a Catholic, subject to all the laws of the Church until they die.

A person may remove themselves from the Church's jurisdiction, but they are the only ones who may do that - the Church cannot.
