Fr. Kramer, Catholics "Bound" to the Traditional Rite
The Novus Ordo Rites pertain to the Modernist's (new faith) Conciliar Church. They are schismatic.
Pope Innocent III explains in De Consuetudine that such changes against the universal custom of the Church are not to be followed; and on the same basis, Juan de Torquemada OP (theologian of Eugenius IV, and Francisco Suarez SJ (named "doctor eximius et pius by Paul V) teach that a pope who would change the sacred rites falls into schism. (This approved teaching has stood for six centuries.) Hence, it is absolutely clear from the dogmatic teaching of the Church that the Novus Ordo is contrary to dogma and custom; a grave violation of the teaching and tradition of the Church, and therefore must not be used in the celebration of the liturgy, even when commanded under the pretense of obedience.
