He can and should be defrocked. The Church of England must do that or begin to become irrelevant.
The Church of England became heretical when Henry VIII did away with the succession of Peter and became HEAD of his own invention: the Church of England. The royalty still are heads of the Church of England.
Broken rules can become a habit when the foundation of said Church, the "Church of England," was based on the doing away with the succession of Peter as vicar of Christ's Church on earth. Jesus told Peter that he, Peter, was the vicar, "Cephas," the ROCK, on which Jesus would build His Church, not the kings and queens of England.
Christ didn't mention earthly kings and queens heading their own Church. Perhaps the C of E became irrelevant when it chose its own path, rather than follow Jesus' path.
Do YOU think they will be defrocked?
