In those things which are clearly laid down in Scripture, all those things are found which pertain to faith and morals. (De Doct. Chr. 2:9)
Whatever you hear from them [the Scriptures], let that be well received by you. Whatever is without them refuse, lest you wander in a cloud. (De Pastore, 11)
All those things which in times past our ancestors have mentioned to be done toward mankind and have delivered unto us: all those things also which we see and deliver to our posterity, so far as they pertain to the seeking and maintaining true religion, the Holy Scripture has not passed over in silence. (Ep. 42)
Whatever our Saviour would have us read of his actions and sayings he commanded his apostles and disciples, as his hands, to write. (De Consensu Evang. 1:ult.)
Let them [the Donatists] demonstrate their church if they can, not by the talk and rumor of the Africans; not by the councils of their own bishops; not by the books of their disputers; not by deceitful miracles, against which we are cautioned by the word of God, but in the prescript of the law, in the predictions of the prophets, in the verses of the Psalms, in the voice of the Shepherd himself, in the preaching and works of the evangelists; that is, in all canonical authorities of the sacred Scriptures. (De Unit. Eccl. 16)
He never says Scripture alone or Tradition alone.Blessed Augustine relied on Scripture,Sacred Tradition and the Magesterium of the Catholic Church, Just like we Catholics do today.
