“All Glory Laud and Honor” starts the service after the Litany of the Palms procession. It was written in exile by Theodulf of Orléans in 820. Theodulph of Orleans appears to have been a native of Italy. He was brought to France by Charles the Great, perhaps when Charles returned from Italy in 781.
It is a Palm Sunday hymn, based on Matthew 21:1–11 and the occasion of Christ’s triumphal entry into Jerusalem.
“All Glory, Laud and Honour” is an English translation by the Anglican clergyman John Mason Neale of the Latin hymn “Gloria, laus et honor”, which was written by Theodulf of Orléans in 820.
