They are secretive, with cultic elements including taking over all of their members' time, forcing them to perform public confession, isolating them from all non-members. They celebrate liturgies of their own design, departing radically from the norms established by Rome. They are not accountable to the hierarchy. Their theology is suspect, in matters such as the Real Presence and the sacrificial nature of the Mass. They are gnostic, posessing a secret catechism, and having various "stages" of membership to which members are admitted only after having satisfied their NC catechists. In short, they are a para-church, powerful and a menace to souls.
That is disturbing and disgusting. I thank you for the information. Has anyone trustworthy done an expose' on them?
