Preacher and "Russian Chrysostom"
Cyril's lasting fame rests on his preaching. His festal homilies were composed for the great moments of the liturgical year, including Palm Sunday, Pascha, the Ascension, and Pentecost. These sermons draw on Saint John Chrysostom and other Greek fathers, reworking their themes in original compositions rather than mere translation, and they treat above all the mysteries of Christ.
One of his most admired works compares the melting of winter's ice in spring to the dissolving of the Apostle Thomas's doubt before the risen Christ. For the splendor of such images contemporaries and later readers called him a "Russian Chrysostom" and a golden-tongued teacher, ranking him among the foremost writers of early Rus'.
