This is the first English translation of the last two theological works of Eusebius of Caesarea, Against Marcellus and On Ecclesiastical Theology. The first text was composed after the deposition of Marcellus of Ancyra in 336 to justify the action of the council fathers in ordering the deposition on the grounds of heresy, contending that Marcellus was “Sabellian” (or modalist) on the Trinity and a follower of Paul of Samosata (hence adoptionist) in Christology. Relying heavily upon extensive quotations from a treatise Marcellus wrote against Asterius the Sophist, this text provides important information about ecclesiastical politics in the period before and just after the Council of Nicea, and endeavors to demonstrate Marcellus’s erroneous interpretation of several key biblical passages that had been under discussion since before the council. In doing so, Eusebius criticizes Marcellus’s inadequate account of the distinction between the persons of the Trinity, eschatology, and the Church’s teaching about the divine and human identities of Christ. On Ecclesiastical Theology, composed circa 338/339 just before Eusebius’s death, and perhaps in response to the amnesty for deposed bishops enacted by Constantius after the death of Constantine in 377 and the possibility of Marcellus’s return to his see, continues to lay out the criticisms initially put forward in Against Marcellus, again utilizing quotations from Marcellus’s book against Asterius. However, we see in this text a much more systematic explanation of Eusebius’s objections to the various elements of Marcellus’s theology and what he sees as the proper orthodox articulation of those elements. Long overlooked for statements at odds with later orthodoxy, even written off as heretical because allegedly “semi-Arian,” recent scholarship has demonstrated the tremendous influence these texts had on the Greek theological tradition in the fourth century, especially on the orthodox understanding of the Trinity. In addition to their influence, they are some of the few complete texts that we have from Greek theologians in the immediate period following the Council of Nicea in 325, thus filling a gap in the materials available for research and teaching in this critical phase of theological development.

A contemporary version of important early Christian texts that are not included in the New Testament. The translation, Greek texts, introduction, notes, and bibliographies are freshly revised.

The Catholic Church is among the oldest, most secretive, institutions in the world, but in the sixteenth century a friar, Onofrio Panvinio, undertook ground-breaking investigations into the Church's history from Christ to the Renaissance. This study shows how his writings impacted on church and society, but also how he changed historical writing.

The theory of apokatastasis (restoration), most famously defended by the Alexandrian exegete, philosopher and theologian Origen, has its roots in both Greek philosophy and Jewish-Christian Scriptures and literature, and became a major theologico-soteriological doctrine in patristics. This monograph—the first comprehensive, systematic scholarly study of the history of the Christian apokatastasis doctrine—argues its presence and Christological and Biblical foundation in numerous Christian thinkers, including Syriac, and analyses its origins, meaning, and development over eight centuries, from the New Testament to Eriugena, the last patristic philosopher. Surprises await readers of this book, which results from fifteen years of research. For instance, they will discover that even Augustine, in his anti-Manichaean phase, supported the theory of universal restoration.
