Bishop Theodulph of Orleans penned the hymn my heart is singing on this Palm Sunday morning, “All Glory, Laud, and Honor.”
It truly is one of my favorites, made more sacred by the fact that we really only sing it once a year.
He is said to have written it from his prison tower, thrown there by King Louis the Debonair, son of Charlemagne.
The story goes that the Bishop wrote this hymn and, in the year 821 as the Emperor passed by on Palm Sunday heading to Mass at the cathedral, he sang it loudly over the passing procession from his stone entombment. The emperor, taken with the song, released the good Bishop.
Truly the rocks themselves will shout for justice.

I’m with you–one of the best of all hymns! What a treasury of hymns some of us have in our minds! And some have in their fingers–the church pianists and organists and all the others who can play those hymns.
