The Choir of St. Ignatius of Antioch Episcopal Church (Douglas Keilitz, Organist & Choirmaster), New York City, sings the motet "O salutaris hostia" by Adrian Willaert (c.1490-1562).
Adrian Willaert was a Flemish composer who was appointed "maestro di cappella" of St. Mark's, Venice in 1527. "O salutaris hostia" is a text which is part of the service of Benediction of the Blessed Sacrament. Willaert's setting incorporates only the first part of the text: "O salutaris hostia quae caeli pandis ostium, bella premunt hostilia: da robur, fer auxilium." In English: "O saving Victim, opening wide the gate of heaven to man below, our foes press on from every side: thine aid supply, thy strength bestow."
