 Since the new group of mysteries are in fact optional, they are, properly speaking, not an integral part of the Rosary of St. Dominic.The Rosary Confraternity does not require its members to recite the new Luminous Mysteries, and Rosarians who continue to recite the 15 mystery Dominican Rosary as received from the ecclesiastical tradition do fulfill their confraternity obligations.The 15 mystery rosary consists of the Joyful, Sorrowful & Glorious Mysteries.
