Ancient natural philosophy in byzantine christology: the issue of penetration of fire into iron

Introduction. The author shows how the Stoic principle of total blending of physical bodies finds its refraction in the Byzantine Christological teachings on the example of penetration of fire into iron. According to the Stoics, total blending occurs when one body accepts certain qualities of the other, however, remaining themselves, or both mixed bodies acquire qualities of each other preserving their natures. Analysis. The author asserts that Origen’s use of the example of iron incandesced by fire turned out to be paradigmatic for the subsequent Christian literature, and influenced the formation of two directions of using this example at once: in Christological context, as well as to describe deification of man. Further, the author addresses to Christological problematics and claims that using the incandesced iron example in Byzantium literature in properly Christological context began with Apollinarius of Laodicea. The paper also investigates the specificity of the refraction of this example in Christological perspective in (Ps.-) Basil of Caesarea, Theodoret of Cyrus, Cyril of Alexandria, Severus of Antioch, John of Damascus, and Corpus Leontianum. Results. In this context, the author pays special attention to the discrepancy between John Damascus and Leontius of Jerusalem regarding the issue of the complexity of Christ’s hypostasis. The researcher clarifies prerequisites of this discrepancy.
