The mid fifth century was largely marked by a Christological controversy that began with private teachings of the ambassador of the Alexandrian see to Constantinople, the prominent Archimandrite Eutyches. The precise teaching of Eutyches remains somewhat obscure, since no written work by him is extant. Thus, everything that the modern historical scholarship knows about Eutyches’ theology comes from secondary sources, such as the writings of his opponents or scontemporary Synodal Acts. Consequently, the fine points of Eutyches’ Christological position are subject (...) of scholarly debate. However, on the basis of the unchallenged contemporary historical evidence, as it is found in the original trial of Eutyches for heresy at the Synod of Constantinople in 448 AD, a critical evaluation of Eutyches’ Christological position seems possible. In this article it was argued that the Christological teaching of Eutyches was inadequate in terms of the later Christological standard set at Chalcedon (451 AD). (shrink)
