Specifically directed to PvK: They also apply to prophets, don't forget(the dominion hp bonus), so your Black Knight can end up with a boatload of hp now.

Just ignore the "Mortal King" thing. He's donning a "godly mantle" as the descriptions keep saying, and is no longer quite mortal.

If you consider a magicless Wyrm can become a God, why not a powerful knight? It's all about faith, once the populace believes in you, you gain strength. Take it in game context, and you'll be much happier.
