Custodi di quella Fede §11

¹¹ Those who, by some supreme misfortune, have given their name to one of these societies of perdition should know that they are strictly bound to separate themselves from it. Otherwise they must remain separated from Christian communion and lose their soul now and for eternity. Parents, teachers, godparents, and whoever has care of others should also know that a rigorous duty binds them to keep their wards from this guilty sect or to draw them from it if they have already entered.
