Muscovite theologian departed from traditional east-Christian patristic teaching, than original Fall generated, within mankind. mortality and inclination to sin, but not the ’’original sin”. Such approach seems to be typical of the traditional East-Slavic medieval Orthodox culture. In Ruthenia, however, the “latinization” of the Orthodox doctrine manifested itself in changing interpretation of the impact of the original Fall upon man. This mutation was reflected by the Ruthenian homiliaries (“Teaching Gospels”) of the late 16th – early 17th centuries.
