does the catholic church group cult called the knight circle exist and if so tell me about the history?

There is no widely recognized or documented group known as the "Knight Circle" within the Catholic Church. It's possible that you could be referring to a specific local organization or a more obscure group, but as of my last update in October 2023, there is no established group with that name that is known to be associated with Catholicism in a mainstream context. In discussing "cult" or fringe groups that claim association with mainstream religions, it's essential to approach with caution, as many such groups can distort religious teachings for their own purposes. If you're seeking information about mainstream groups within the Catholic Church that involve knights or chivalric orders, you might be thinking of the "Knights of Columbus," which is a well-known fraternal service organization for Catholic men. If you have more specific information or context about the "Knight Circle," I would be happy to help clarify further!
