Thoughts:
What is the potential of this to be abused IG?
The potential lies in the exclusion of other, legitimate attempts to create substantiative religions IG. It's also worth noting that the only illegal act in the realm is founding a religion. Even looting is circumstantial, while magic and spell-casting are explicitly allowed.
According to game mechanic, is still a religion if is founded like a religion (even if have another name and people use it to RP other thing) and to get people's sympathy they have to preach, and to preach they must be priest, and if they are priest they believe in something.
The mechanics of a religion are all predicated on the idea that the religion adheres to the rules Tom laid out for them, which is that they actually function as religions. The Path of Chivalry has no divinity, no higher order, and no real congregation of the faithful. There are actual guilds and secret societies on other continents that do exactly what this religion purports to do. That's why we have guilds and societies—to champion these kinds of "beliefs".
