Eranistes

This translation of a major document in patristic Christology, the first translation since the nineteenth century, is based upon the modern critical edition of Theodoret's Greek text. Theodoret was the leading theologian of his time in the Antiochene tradition, and in the Eranistes (written in 447) he offers a lengthy exposition of his Christology, coupled with a refutation of the so-called Monophysite Christology that, despite its condemnation at the General Council held at Chalcedon in 451, survives to this day, having been embraced by several large churches of the East. The ""Monophysite"" controversy caused a tremendous rift between East and West, and the Eranistes portrays the hostility and the stubborn resistance to the thought of others that afflicted both sides in the conflict.

The Eranistes is written in the form of three dialogues between two characters: Orthodox, who represents Theodoret's thought, and Eranistes, who is presented as a heretic. In two dialogues Theodoret argues that the Word of God was immutable and impassible in his divine nature, and that Christ experienced change and passion only in his human nature. A third dialogue argues that, in the union of the divinity and humanity in the one person of the Word incarnate, the natures remained unmixed. To bolster his arguments Theodoret incorporates extensive citations, not only from orthodox ecclesiastical writers, but also from the heretic Apollinarius and the suspected Arian, Eusebius of Emesa. The texts of many of these citations are known only from the Eranistes and are therefore important witnesses to the development of patristic Christology.

Critical issues in Antiochene and Alexandrian Christology are broached by Theodoret in the text and are further discussed by the translator in the introduction and notes.
