Holy Week for the Christians is an accumulation of events leading up to the actual Crucifixion of Jesus of Nazareth and His resurrection. Let me recall them:
Sunday starts the Holy Week with The Christ riding on a donkey, backward into Jerusalem fulfilling a prophecy of the prophets of old.
Afterword this got out to the High Jewish Council, they began to plot to kill Jesus. On Wednesday, Jesus was in Bethany, in the house of Simon the Leper, where a woman named Mary anointed his head and feet with oil. A ritual performed for Kings and Sages…it is here Judas plots to betray Jesus…thus now known as Spy Wednesday as well Good/Holy Wednesday, the following day is known as Maundy Thursday, this is the day of the Last Supper and the next day, Good Friday when Jesus of Nazareth is crucified.
Today, the day after Good Friday is known as Holy Saturday or The Great Sabbath…since it is on this day that Jesus “rested” in the tomb and Easter Sunday Resurrected from the dead.
