O salutaris hostia, or O saving host, is a Latin hymn usually sung during communion, or during the adoration before the sacrament in a service of Benediction. It is also suitable for Corpus Christi and Maundy Thursday. This setting draws on the mystical and intangible nature of believing in such a wonderful mystery as God comes to us in the Eucharist.

It twins historical composition techniques with a more modern, yet accessible, harmonic style.
