You seem to have forgotten that part of Brenda’s title which runs “Defender of the Faith”.
She’s the supreme governor of the Church of England. And the Monarchy is still based on “God’s Ordinance” per the 39 Articles.
We tend to forget this, but the monarchy is an ancient institution and the root of its claim to supreme power in the realm is that they rule by Grace of God.
(This irritates those of us who don’t believe in an Invisible Sky Daddy. But it doesn’t mean that line of hereditary monarchs don’t rest their claim to rule on the assertion that God gave them the right to do so.)
