The author praises Gratian’s zeal for instruction in the Faith, and speaks lowly of his own merits. Taught of God Himself, the Emperor stands in no need of human instruction; yet this his devoutness prepares the way to victory. The task appointed to the author is difficult: in the accomplishment whereof he will be guided not so much by reason and argument as by authority, especially that of the Nicene Council.

Aurelius Ambrosius, better known in English as Saint Ambrose (c. between 337 and 340 - 4 April 397), was a bishop of Milan who became one of the most influential ecclesiastical figures of the 4th century. He was one of the four original doctors of the Church. There is a legend that as an infant, a swarm of bees settled on his face while he lay in his cradle, leaving behind a drop of honey. His father considered this a sign of his future eloquence and honeyed tongue. For this reason, bees and beehives often appear in the saint's symbology. After the early death of his father, Ambrose followed his father's career. He was educated in Rome, studying literature, law, and rhetoric. As bishop of Milan, he immediately adopted an ascetic lifestyle, apportioned his money to the poor, donating all of his land, making only provision for his sister Marcellina (who later became a nun),[2] and committed the care of his family to his brother. Ambrose also wrote a treatise by the name of "The Goodness Of Death". On the eve of setting out for the East, to aid his uncle Valens in repelling a Gothic invasion, Gratian, the Emperor of the West, requested St. Ambrose to write him a treatise in proof of the Divinity of Jesus Christ. Gratian's object in making this request was to secure some sort of preservative against the corrupting influence of Arianism, which at that time (a.d. 378) had gained the upper hand of Orthodoxy in the Eastern provinces of the Empire, owing to its establishment at the Imperial Court. In compliance with Gratian's wish, the Bishop of Milan composed a treatise, which now forms the first two Books of the De Fide. With this work the Emperor was so much pleased that on his return from the East, after the death of Valens at Hadrianople, he wrote to St. Ambrose, begging for a fresh copy of the treatise, and further, for its enlargement by the addition of a discourse on the Divinity of the Holy Spirit. The original treatise was, indeed, enlarged by St. Ambrose in 379, but the additional Books dealt, not with the Divinity of the Holy Spirit, but rather with new objections raised by the Arian teachers, and points which had either been passed over or not fully discussed already. In this way St. Ambrose's Exposition was brought into its present form.

This is St. Ambrose's thorough overview of the Christian faith. What it is, what it means and how we apply it to our lives. Not only was it a necessity for the early Church, but it applies equally for us today.

Saint Ambrose, also known as Aurelius Ambrosius, is one of the four original doctors of the Church. He was the Bishop of Milan and became one of the most important theological figure of the 4th century. He is considered a saint by the Catholic Church, Eastern Orthodox Church, Anglican Communion, and various Lutheran denominations, and venerated as the patron saint of Milan. Ambrose's intense episcopal consciousness furthered the growing doctrine of the Church and its sacerdotal ministry, while the prevalent asceticism of the day, continuing the Stoic and Ciceronian training of his youth, enabled him to promulgate a lofty standard of Christian ethics. Thus we have the De officiis ministrorum, De viduis, De virginitate and De paenitentia. In De Officiis, the most influential of his surviving works, and one of the most important texts of patristic literature, he reveals his views connecting justice and generosity by asserting these practices are of mutual benefit to the participants.

These sermons by Ambrose of Milan (340–397 AD) provide a window into the preaching and scriptural exegesis of the legendary bishop, whose exposition of the Old Testament was instrumental in the conversion of Augustine of Hippo and in the development of Latin theology. In his treatise On Noah and his two Defenses for David, Ambrose borrows from influential Greek theologians, including Philo of Alexandria, Origen, and Didymus the Blind, while developing his own commentary on the exemplary patriarchs. Ambrose’s exegesis typifies both his attention to the letter of Scripture as well as his spiritual and allegorical reading of the holy figures or “saints” who lived before Christ. The first treatise presents Noah as a model just man, as Ambrose pairs the literal and the higher or spiritual meaning of the Genesis flood narrative to address topics ranging from the Genesis narrative to Stoic ethics to the Incarnation. In his defense of David to the emperor Theodosius, Ambrose ties David’s sin and repentance to his own close reading of Psalm 51(50), David’s plea for himself in his famous “Miserere.” While the authenticity of the third treatise included in the volume, the Second Apology of David, has long been challenged, recent scholarship suggests that it transmits Ambrose’s own preaching, which applies the lessons of David’s life to the situation of gentile unbelievers, Jews, and the church; even if it is the work of a later imitator, the Second Apology is a compelling and systematic treatment of the David’s sin and repentance as relevant to Christian morality and doctrine. The three treatises, previously unavailable in English translation, broaden our understanding of exegesis in the Latin West and our interpretation of Ambrose as preacher and exegete.
