There are two problems with this:
1) I have yet to see substantive evidence that Prince Charles has any faith in any recognizable relgion.
2) even if he did, the Anglican Church in England has no recognizable doctrinal stance, therefore no recognizable faith to defend.
You are quite wrong about the Anglican Church! It is an Orthodox Christian Church that believes in the Divinity of Christ and that the Bible is the inspired Word of God.
The Anglican Church in America will soon replace the ultra-Leftist, heretical Episcopal Church as the Anglican Communion's American entity.
