“Holy, holy holy is the Lord God of hosts! Heaven and earth are full of his glory!” Isaiah heard the angels crying out to one another, and this hymn shook the very foundations of the Temple – and of Isaiah’s own soul. I believe the Sanctus (“Holy!”) ought to convey awe in the face of the profound mystery of our Lord’s self-giving revelation in the Sacrament. And it should convey deep love: God’s love for us, and our response of love for Him. What better hymn tune to convey all this than yet another early American tune: Wondrous Love? My feeble words lean totally on Scripture, and are carried by this lovely melody.
