The Palm Sunday anthem "All Glory Laud and Honor" is one of Christendom's oldest hymns.  St. Theodulf of Orleans, who helped reform the church under Charlemagne, wrote the lyrics in the year 820 while imprisoned in France.
       The lyrics recount Jesus' triumphal entry into Jerusalem, an event the medieval church reenacted every Palm Sunday.  Clergy and townspeople processed from fields through the city gates, behind a Jesus figure riding a donkey.  At the gates, children began singing the hymn in Latin - Gloria, laus et honor- and onlookers soon chimed in.
         City gates may be a thing of the past, as the website Hymnary.org notes, yet we still praise our blessed Redeemer "because we know just what kind of King he was and is - an everlasting King who reigns not just in Jerusalem but over the entire earth.  What more could we do but praise him with glory, laud and honor."
                     All glory, laud and honor to you Redeemer, King, to whom the lips of children made sweet hosannas ring.
                    You are the King of Israel and David's royal Son, now in the Lord's name coming, the King and Blessed one.
