Today is one of the Holiest Days of the Christian Faith, known as Palm Sunday, the day that commemorates Jesus' triumphal entry into Jerusalem. Where I grew up, the Easter season was fairly universally and solemnly observed. Sunday School children would be part of a procession, waving palm fronds, as imagined happened thousands of years ago as Jesus and his disciples prepared to celebrate Passover in Jerusalem. The story of people shouting "Hosanna" and waving palm branches, laying down their robes, as he rode a donkey into the town was told and retold in Sunday Schools and in churches until it became part of the familiar Easter Story.
In the Jewish tradition, Passover begins at sundown tomorrow evening.
