聖金口イオアン聖体礼儀
The Liturgy of St. John Chrysostom (, tr. "Liturhiya Ivana Zlatoustoho") is the musical setting of the Divine Liturgy of St. John Chrysostom by Mykola Leontovych. Consistent with Orthodox tradition, in which service is sung exclusively a cappella, the piece is set for unaccompanied choir and soloist. It was first performed in the Mykolaiv Cathedral at the Kyiv Pechersk Lavra on May 22, 1919, with Leontovych himself conducting.
