Church and Scripture

For St. Augustine, it was never a question of Scripture or the Catholic Church; it was always Scripture and the Catholic Church.

But You suffered me not to be carried away from the faith by any fluctuations of thought, whereby I believed You both to exist, and Your substance to be unchangeable, and that You had a care of and would judge men; and that in Christ, Your Son, our Lord, and the Holy Scriptures, which the authority of Your Catholic Church pressed upon me, You had planned the way of man's salvation to that life which is to come after this death. [Confessions VII.7]

Of course, he also accepted the authority of Sacred Tradition…but that’s not in view in this portion of the Confessions.
