The angels in the life of the Church
In her liturgy, the Church joins with the angels to adore the thrice-holy God. She invokes their assistance (in the Roman Canon's Supplices te rogamus. . .["Almighty God, we pray that your angel..."]; in the funeral liturgy's In Paradisum deducant te angeli. . .["May the angels lead you into Paradise. . ."]). Moreover, in the "Cherubic Hymn" of the Byzantine Liturgy, she celebrates the memory of certain angels more particularly (St. Michael, St. Gabriel, St. Raphael, and the guardian angels).
