The whole thing begins with clergy washing the hands of the people. After the Seder, at the back of the church, we move forward towards the altar where the Liturgy of the Last Supper takes place. I always have two Presbyterian ministers on each side of me at the altar.
Then the Solemn stripping of the Altar, the procession to the Altar of Repose, and a watch until midnight. Five hours of solid symbolism which seems to touch so many deeply.
