Ottaviani Intervention

Short Critical Study of the Novus Ordo Missae (Italian: Breve Esame Critico del Novus Ordo Missae), nicknamed the Ottaviani Intervention, is a 1969 document written by some Roman Catholic theologians addressed to Pope Paul VI to criticise what those theologians perceived as problems in the Mass of Paul VI—also called "Novus Ordo Missae"—which had been promulgated earlier the same year. The surname of the document comes from one of its writers, Alfredo Ottaviani.
