It was included as an antiphon to Magnificat in the vespers of the liturgical office on the feast of Corpus Christi. The text of the office is attributed with some probability to Saint Thomas Aquinas. Its sentiments express the profound affinity of the Eucharistic celebration, described as a banquet, to the Paschal mystery: O sacred banquet at which Christ is consumed, the memory of his Passion is recalled, our souls are filled with grace, and the pledge of future glory is given to us.
