In today's Office of Readings we encounter a reading from an instruction by St Vincent of Lérins (ca. -445 A.D.). Vincent was born in Toulouse and after a secular career he joined the abbey of Lérins, on an island just offshore from the French Riviera town of Cannes. He took part in the major theological controversies of the day, which were far from sterile academic squabbling but were part of the vital process of finding out what precisely Christianity is. He opposed Nestorianism, defending the status of Mary as Mother of God. He enunciated the famous principle that “In the Catholic Church itself, all possible care must be taken, that we hold that faith which has been believed everywhere, always, by all (quod semper, quod ubique, quod ab omnibus)”.
