If we accept that monarchy will be established on the ruins of previous system then this is obvious that the new king will be chosen by God who give him courage to act and inspire some group of faithful Catholics to back his claims. This is the best interest of all member of the Church of the Christ to achieve this goal faster than every other leftist idiot willing to establish some dictatorship.
If he tried to exert unelected authority over me, there would be only one decision for you and your Catholic followers to make about your monarch; closed or open casket.
I will adjust my aim accordingly.
