There is a very complete agreement on the part of St. Ambrose with the Catholic teaching of the universal Church. St. Augustine speaks of him as “a faithful teacher of the Church, and even at the risk of his life a most strenuous defender of Catholic truth,” Cont. Jul. Pelag. II. 32. “whose skill, constancy, labours, and perils, both on account of what he did and what he wrote, the Roman world unhesitatingly proclaims.” Cont. Jul. Pelag. I. 40. In matters both of faith and morals by his words and writings he greatly benefited the Church and was called by St. Jerome “a pillar of the Church.” Adv. Rufin. I. 2.
