The following dissertation concerning the Trinity, as the reader ought to be informed, has been written in order to guard against the sophistries of those who disdain to begin with faith, and are deceived by a crude and perverse love of reason. Now one class of such men endeavor to transfer to things incorporeal and spiritual the ideas they have formed, whether through experience of the bodily senses, or by natural human wit and diligent quickness, or by the aid of art, from things corporeal; so as to seek to measure and conceive of the former by the latter.

"As the psalms are a microcosm of the Old Testament, so the Expositions of the Psalms can be seen as a microcosm of Augustinian thought. In the Book of Psalms are to be found the history of the people of Israel, the theology and spirituality of the Old Covenant, and a treasury of human experience expressed in prayer and poetry. So too does the work of expounding the psalms recapitulate and focus the experiences of Augustine's personal life, his theological reflections and his pastoral concerns as Bishop of Hippo."--Publisher's website.

Augustine of Hippo (354–430) strongly influenced western theology, but he has often been accused of over-emphasizing the unity of God to the detriment of the Trinity. In Augustine and the Trinity, Lewis Ayres offers a new treatment of this important figure, demonstrating how Augustine's writings offer one of the most sophisticated early theologies of the Trinity developed after the Council of Nicaea (325). Building on recent research, Ayres argues that Augustine was influenced by a wide variety of earlier Latin Christian traditions which stressed the irreducibility of Father, Son and Spirit. Augustine combines these traditions with material from non-Christian Neoplatonists in a very personal synthesis. Ayres also argues that Augustine shaped a powerful account of Christian ascent toward understanding of, as well as participation in the divine life, one that begins in faith and models itself on Christ's humility.

With: Historical commentary Biographical info Appendix with further readings For nearly 2,000 years, Christian mystics, martyrs, and sages have documented their search for the divine. Their writings have bestowed boundless wisdom upon subsequent generations. But they have also burdened many spiritual seekers. The sheer volume of available material creates a seemingly insurmountable obstacle. Enter the Upper Room Spiritual Classics series, a collection of authoritative texts on Christian spirituality curated for the everyday reader. Designed to introduce 15 spiritual giants and the range of their works, these volumes are a first-rate resource for beginner and expert alike. Writings of Augustine compiles some of the most profound and moving writings of the 4th-century African Christian who had a vast influence on the Christian church and Western culture. Included are excerpts from Augustine's Confessions and other writings.

Augustine inaugurated the project of constructing models of the Trinity in language drawn from Platonic and Aristotelian philosophy, especially the conceptual framework of Aristotle's Categories. He used the Aristotelian notions of substance and relation to set up a model whose aim was not so much to demystify the Trinity as to demonstrate the logical consistency of maintaining that there is one and only one God at the same time as maintaining that there are three distinct persons, each of whom is God. Standing against this tradition are various heretical accounts of the Trinity. The book also analyzes these traditions, using the same techniques. All these accounts of the Trinity are evaluated relative to the three constraints under which they were formed, bearing in mind that the constraints on philosophical theorizing are not limited to internal consistency but also take note of explanatory power.

The legacy of Augustine of Hippo (354-430) continues to shape Western Christian language about both the Trinity and the Church, yet scholars rarely treat these two topics as related in his work. In Augustine, the Trinity, and the Church, Adam Ployd argues that Augustine's ecclesiology drew upon his Trinitarian theology to a surprising degree; this connection appears most clearly in a series of sermons Augustine preached in 406-407 against the Donatists, the rival Christian communion in North Africa. As he preached, Augustine deployed scriptural interpretations derived from his Latin pro-Nicene predecessors - but he adapted these Trinitarian arguments to construct a vision of the charitable unity of the Catholic Church against the Donatists. To condemn the Donatists for separating from the body of Christ, for example, Augustine appropriated a pro-Nicene Christology that viewed Christ's body as the means for ascent to his divinity. Augustine also further identified the love that unites Christians to each other and to Christ in his body as the Holy Spirit, who gives to us what he eternally is as the mutual love of Father and Son. On the central issue of baptism, Augustine made the sacrament a Trinitarian act as Christ gives the Spirit to his own body. The book ultimately shows that, for Augustine, the unity and integrity of the Church depended not upon the purity of the bishops or the guarded boundaries of the community, but upon the work of the triune God who unites us to Christ through the love of the Spirit, whom Christ himself gives in baptism.

There is no doubting the legacy of the Protestant Reformers and their successors. Luther, Calvin, and Wesley not only spawned specific denominational traditions, but their writings have been instrumental in forging a broadly embraced evangelical theology as well. In this volume, Ben Witherington wrestles with some of the big ideas of these major traditional theological systems (sin, God's sovereignty, prophecy, grace, and the Holy Spirit), asking tough questions about their biblical foundations. Witherington argues that evangelicalism sometimes wrongly assumes a biblical warrant for some of its more popular beliefs, and, further, he pushes the reader to engage the larger story and plot of the Bible to understand these central elements of belief. --Donald K.
