It is a preponderance of evidence thing, they're a historical organization founded by the future Holy Roman Emperor to "defend the Catholic Church from heretics and pagans," which at the time meant the Ottoman Empire, so at the very least it appears that it was part of the Catholic Church in the 15th century; meanwhile, in universe there's a Catholic priest's assertion that it was in fact a militant Catholic order in, as well as the presence of a Catholic bishop accompanying the self-described "warrior-priests" into battle in.

That being said, if the objection is purely the nesting, then I think it should be the Order's links that are removed from #17-20, not the other way 'round; meanwhile, the Church should still be listed throughout both arcs as Father Jordan is very clear that he's acting as Matt's priest therein.
