This was sung throughout the Triduum at my parish, and most triumphantly last night, for the Vigil, with the Easter verses.
I love it. I selected this for the entrance hymn at my Mass of Thanksgiving, too. Our choir always does a spectacular job with it. Here, a thrilling version from the choir at Notre Dame, featuring the verses of Easter.
Out of darkness, God has called us,
Claimed by Christ as God’s own people,
Holy nation, royal priesthood,
Walking in God’s marv’lous light.
Happy Easter. He is risen! “This is Resurrection Day!”
