RESPONSORIAL PSALM (The Cup of blessing is a participation in the blood of Christ)

When we gather in the choir loft for the Mass of the Lord's Supper on Holy Thursday, the liturgy shifts our focus directly to the institution of the Eucharist. This responsorial psalm, "The Cup of blessing is a participation in the blood of Christ," captures the profound solemnity and gratitude of that evening. Ukanyirioha Francis C. sets the antiphon with a steady, reverent harmony that anchors the congregation before moving into the cantor's verses.

The verses ask a question every believer faces: "How can I repay the Lord for His goodness to me?" The answer is found in the very action of the Mass itself—raising the cup of salvation and offering a thanksgiving sacrifice. Singing this on Holy Thursday, just before the washing of the feet and the procession to the altar of repose, brings a deep sense of intimacy to the liturgy. The melody supports the natural rhythm of the words, allowing the cantor to deliver the psalm clearly so the people can meditate on the gift of the Eucharist.

It is a straightforward, prayerful arrangement that works beautifully for a parish choir. The SATB refrain is easy for the congregation to pick up, ensuring they can fully participate in the response, while the verses give the cantor room to lead the church in reflection.
