New Testament I and II contains the translations of four works, all of which are exegetical treatises of one sort or another. Each of the four works is accompanied by its own introduction, general index, and scripture index. For all those who are interested in the greatest classics of Christian antiquity, Augustine's works are indispensable. This long-awaited translation makes his monumental work approachable.
The Lord's Sermon on the Mount discusses chapters five through seven of Matthew's Gospel. Augustine's explanation of the Sermon is more a charter of Christian morality and spirituality than mere exegesis of the text and brings a unity to the lengthy discourse that goes far beyond a simple account of what the text says.
Augustine wrote Agreement among the Evangelists in 400, contemporaneously with the composition of his Confessions (397-401). This treatise is an attempt to defend the veracity of the four evangelists in the face of seeming incompatibilities in their record of the gospel events, especially against some pagan philosophers who raised objections to the gospel narratives based on alleged inconsistencies.
Questions on the Gospels is a record of questions that arose when Augustine was reading the Gospels of Matthew and Luke with a disciple. The answers to the questions are not intended to be commentaries on the Gospels in their entirety but merely answer the questions that arose for the student at the time.
Seventeen Questions on Matthew is similarly in the question-and-answer genre and is most likely by Augustine, but it includes some paragraphs at the end that are certainly not his.

Augustine of Hippo (13 November 354 - 28 August 430 AD[20]), also known as Saint Augustine, was a theologian, philosopher, and the bishop of Hippo Regius in Numidia, Roman North Africa. His writings influenced the development of Western philosophy and Western Christianity, and he is viewed as one of the most important Church Fathers of the Latin Church in the Patristic Period. His many important works include The City of God, On Christian Doctrine, and Confessions.
According to his contemporary, Jerome, Augustine "established anew the ancient Faith".[a] In his youth he was drawn to the major Persian religion, Manichaeism, and later to Neoplatonism. After his conversion to Christianity and baptism in 386, Augustine developed his own approach to philosophy and theology, accommodating a variety of methods and perspectives.[21] Believing the grace of Christ was indispensable to human freedom, he helped formulate the doctrine of original sin and made significant contributions to the development of just war theory. When the Western Roman Empire began to disintegrate, Augustine imagined the Church as a spiritual City of God, distinct from the material Earthly City.[22] His thoughts profoundly influenced the medieval worldview. The segment of the Church that adhered to the concept of the Trinity as defined by the Council of Nicaea and the Council of Constantinople[23] closely identified with Augustine's On the Trinity.
Augustine is recognized as a saint in the Catholic Church, the Eastern Orthodox Church, and the Anglican Communion. He is also a preeminent Catholic Doctor of the Church and the patron of the Augustinians. His memorial is celebrated on 28 August, the day of his death. Augustine is the patron saint of brewers, printers, theologians, and a number of cities and dioceses.[24] Many Protestants, especially Calvinists and Lutherans, consider him one of the theological fathers of the Protestant Reformation due to his teachings on salvation and divine grace.[25][26][27] Protestant Reformers generally, and Martin Luther in particular, held Augustine in preeminence among early Church Fathers. Luther was, from 1505 to 1521, a member of the Order of the Augustinian Eremites.
In the East, his teachings are more disputed and were notably attacked by John Romanides.[28] But other theologians and figures of the Eastern Orthodox Church have shown significant approbation of his writings, chiefly Georges Florovsky. The most controversial doctrine associated with him, the filioque,[30] was rejected by the Orthodox Church.[31] Other disputed teachings include his views on original sin, the doctrine of grace, and predestination.[30] Nevertheless, though considered to be mistaken on some points, he is still considered a saint and has influenced some Eastern Church Fathers, most notably Gregory Palamas.[32] In the Orthodox Church his feast day is celebrated on 15 June. Historian Diarmaid MacCulloch has written: "Augustine's impact on Western Christian thought can hardly be overstated; only his beloved example Paul of Tarsus, has been more influential, and Westerners have generally seen Paul through Augustine's eyes."
