The most weighty of the doctrinal treatises is that on the Holy Trinity. The Latin original (De Trinitate contra Arianos libri quindecim), is contained in the 8th volume of the Benedictine edition. It is the most elaborate, and probably also the ablest and profoundest patristic discussion of this central doctrine of the Christian religion, unless we except the Orations against the Arians, by Athanasius, "the Father of Orthodoxy," who devoted his life to the defense of the Divinity of Christ. Augustine, owing to his defective knowledge of Greek, wrote his work independently of the previous treatises of the Eastern Church on that subject. He bestowed more time and care upon it than on any other book, except the City of God. Besides this treatise the following works are included: The Enchiridion, or On Faith, Hope and Love, On the Catechising of the Uninstructed, Treatise on Faith and the Creed, Concerning Faith of Things not Seen, On the Profit of Believing On the Creed.

This volume is accurately annotated, including * an extensive biography of the author and his life * working interactive footnotes The moral treatises contain much that will instruct and interest the reader; while some views will appear strange to those who fail to distinguish between different ages and different types of virtue and piety. Augustine shared with the Greek and Latin fathers the ascetic preference for voluntary celibacy and poverty. He accepted the distinction which dates from the second century, between two kinds of morality: a lower morality of the common people, which consists in keeping the ten commandments; and a higher sanctity of the elect few, which observes, in addition, the evangelical counsels, so called, or the monastic virtues. He practiced this doctrine after his conversion. He ought to have married the mother of his son; but in devoting himself to the priesthood, he felt it his duty to remain unmarried, according to the prevailing spirit of the church in his age. His teacher, Ambrose, and his older contemporary, Jerome, went still further in the enthusiastic praise of single life. We must admire their power of self-denial and undivided consecration, though we may dissent from their theory. Contents: St. Augustine: On Continence.

These questions are irresistible to ponder. The Bible says, "For who has known the mind of the Lord? Or who has been His counselor? Or who has ever first given to Him, and has to be repaid? For from Him and through Him and to Him are all things" (Romans 11:34-36a, Holman CSB).

George Smeaton (1814–-89) was a theologian in the Free Church of Scotland, and a contemporary of Robert Murray McCheyne and the brothers Andrew and Horatius Bonar. He is best known for his twin volumes, "Christ's Doctrine of the Atonement" and "The Apostles' Doctrine of the Atonement."

A Distinguished Theologian on the Doctrine of the Holy Spirit Distinguished theologian Matthew Levering offers a historical examination of the doctrine of the Holy Spirit, defending an Augustinian model against various contemporary theological views. A companion piece to Levering's Engaging the Doctrine of Revelation, this work critically engages contemporary and classical doctrines of the Holy Spirit in dialogue with Orthodox and Reformed interlocutors. Levering makes a strong dogmatic case for conceiving of the Holy Spirit as love between Father and Son, given to the people of God as a gift.

The Formation of Christian Doctrine is a high-level academic study of the history of Christian doctrinal development. The book distinguishes at length between the scholarly term “inventio” (making explicit what is implicit in the biblical revelation) and the idea of “invention” (presenting a novelty as Christian teaching that conflicts with the biblical revelation). Specifically, The Formation of Christian Doctrine identifies biblical inerrancy as an inventio but sees the “priesthood of believers” concept as a license to believe “whatever teaching seems right to me.” Sure to be of interest in academic circles, even to those who might disagree with the author, this book will appeal to three major groups: Evangelicals in relation to the twentieth-century development of a detailed doctrine of biblical inerrancy, Baptists in light of both biblical inerrancy and the seventeenth-century development of believer’s baptism, and Roman Catholics because of their respect for tradition and interest in such a challenging conservative Protestant perspective as is found here.
