Lauda Sion Salvatorem. Lauda Sion, Praise our Savior and our King, Lauda Sion, let the air with praises ring! Lauda Sion, O Zion to our Savior sing Lauda Sion, O sing unto our Shepherd and King. Lauda Sion, Hail Angelic bread of Heaven. Lauda Sion, to the Twelve by Christ was given Lauda Sion, Hail true body born of a virgin. Lauda Sion, Jesu, Lamb of God, Redeemer. Jesus, Good Shepherd, true bread, You who feed us, protect us mere mortals here below. Lauda Sion, we will sing of your glory forever. Lauda Sion, Sing Alleluia, Allelu, Amen. O sing, Zion sing to your God and King! Lauda Sion, let your praise be loud and high. Lauda Sion, On this festival day His glory be praised. Allelu, Amen.
