This service, in which the chalice containing the blessed sacrament is placed upon the altar and venerated (separately from the liturgy), was initiated some time around the 1940s in Eastern Rite Catholic churches. While this veneration comes directly from the Roman Catholic practice, the prayers reflect Eastern thought. Largely eliminated in the Byzantine Catholic/Greek Catholic churches in the USA, I heard it at the Greek Catholic Catholic Cathedral in Prague on the Sunday of the Last Judgement. The music is typically Carpatho-Rusyn, and one can hear the penitential nature of both words and music together as the congregation kneel before God and humbly ask for protection and forgiveness of sins.
Each verse is sung first by the priest and repeated by the congregation. The singing is in Church Slavonic, with an English translation below.
1. Holy God, Holy and Mighty, Holy and Immortal, Have mercy on us (3).
2. From tempest, famine, fire, and war, save us, O Lord.
3. From wantonness and an unrepentant death, preserve us, O Lord.
4. We sinners beseech you O God, hear us, O Lord. (three times)
5. O Jesus, O Jesus, O Jesus, Son of God in the highest, be merciful to us.
6. O Mary, O Mary, O Mary, Virgin and Mother of God, intercede for us.
7. O Saint Joseph, Protector of the Catholic Church, pray to God for us sinners. (In the past this was O Holy Father Nicholas, Patron of the Greek Catholic Church...)
8. O Holy Saints and Martyrs, pray to God for us sinners.
