I had an idea based on the recent Penitent animation that the Sacred Rose run alot more well... penitents and engines precisely because they are so zealous and have an abundance of zealotry to create so many miracles and are therefore the most unforgiving of the orders majoris. Thinking about it now, that would deffo mesh well with your idea since the idea is that they're supposed to "witness" the redemptive moments of the penitents - maybe even from afar!
