A solemn musical setting for the hymn «Of Thy Mystical Supper,» which serves as the Cherubic Hymn, the Communion Hymn, and the response during the Great Entrance on Great and Holy Thursday. This profound prayer of humility and faith before the Holy Eucharist is a cornerstone of the Lenten and Passion Week liturgical services. This arrangement is adapted for English-speaking choirs, preserving the prayerful intensity of the traditional chant.
