Monarchism reigns in Aurvandil.
Mendicant hasn't declared war on religion, he's merely rejected it within his own dominion. He certainly hasn't stated an intent to destroy religions external to his own Commonwealth. You don't need a church when you have a Monarchy, you don't need the promises of a religion when you have the earthly benevolence of Monarchism, and you soon find that God's become irrelevant in the shadow of a true Monarch, after all, God's were only ever modeled on the majesty of Monarchs.
You could call Mendicant a God-King, but that would just belittle the royal person as something seemingly inferior to the Highest of Sovereigns.
