Palm Sunday is the Sunday before Easter.  It introduces the "Holy Week" for Roman Catholics and those who follow their tradition.  It commemorates Jesus' triumphal entry into Jerusalem when the people waved palm branches praising and welcoming him (John 12:13).  This holy day with it elaborate services dates from the 4th century A.D. (Oxford Dictionary of the Christian Church, p. 1008).  Among the ceremonies observed on this day are the blessing of palm branches used by participants, a procession representing Jesus' entrance into the city.  This is usually graced with a carved representation of Christ, an ornate crucifix, a copy of the Gospels, or a carved figure of one seated upon a donkey.  The elaborate ritual dates from the middle ages, although it is now much subdued in the Western world.  Modern clerics now call the day, "Passion Sunday."

While Jesus certainly did enter Jerusalem riding on the fold of a donkey, neither he nor the apostles instructed us to have a special holy day and services to commemorate it.  The traditions and ceremonies of this day are the inventions of men. As Christians we assemble on the first day of every week just as the early Christians did (Acts 20:7; I Cor. 16:1-2).  We remember our Lord's death on the cross.  We celebrate his resurrection.  We praise his greatness and goodness.  We study his word and worship as he has directed.  We have no other special holy days since Christ, the founder and head of the did not teach us to have them (II John 9-11).
