Arianism is the theological teaching attributed to Arius (ca. AD 250–336), a Christian presbyter in Alexandria, Egypt, concerning the relationship of God to the Son of God (Jesus of Nazareth). Arius asserted that the Son of God was a subordinate entity to God the Father. Deemed a heretic by the Ecumenical First Council of Nicaea of 325, Arius was later exonerated in 335 at the regional First Synod of Tyre, and then, after his death, pronounced a heretic again at the Ecumenical First Council of Constantinople of 381.Athanasius of Alexandria (b. ca. 296-298 – d. 2 May 373), also referred to as St. Athanasius the Great, St. Athanasius I of Alexandria, St Athanasius the Confessor and (primarily in the Coptic Orthodox Church) St Athanasius the Apostolic, was the 20th bishop of Alexandria. His episcopate lasted 45 years (c. 8 June 328 – 2 May 373), of which over 17 were spent in five exiles ordered by four different Roman emperors. He is considered to be a renowned Christian theologian, a Church Father, the chief defender of Trinitarianism against Arianism, and a noted Egyptian leader of the fourth century.

The Great Athanasius is an introductory survey of the life and work of the most dynamic pastor-theologian of the fourth century. From his birth and early years in Alexandria to the "Golden Decade," the book charts the life and work of Athanasius through a close study of his main writings and other important works. Central to his story is the "Arian controversy," the Council of Nicea, and the subsequent difficulties that emerged in building a consensus around the "very God, very Man" affirmation of the Nicene Creed. The eventual triumph of the theology of the Nicene Creed was largely due to his tireless efforts, which are carefully chronicled in this work. Though a controversial figure in his own lifetime, through both his theological insight and ecclesiastical leadership, and in his fidelity to his faith convictions, Athanasius proved to be "the great" church father and theologian of his age and one of the seminal Christian thinkers of all time.

"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.
