Palm Sunday celebrates Jesus’ return to Jerusalem. According to the gospels, the people in Jerusalem waved and spread branches on the ground. Palm Sunday is the turning point in Jesus’ ministry. This is the first time that he is publicly recognized as the Messiah, the Son of God. Holy Thursday, also known as Maundy Thursday is significant because of three key events. First, Jesus shows his disciples through the washing of their feet, the true meaning of being a servant to each other. Second, by declaring the bread and wine as His flesh and blood, Jesus demonstrates the way in which He will always be with us, even after death. Finally, it is on this night that Jesus is betrayed by Judas thereby fulfilling the prophecies of His life and death. On Good Friday Christians often reflect, through fasting and prayer, on the carrying of the cross and the crucifixion of Jesus. From the time of the betrayal to His death, Jesus experiences the abandonment of his disciples, the tribulations of Pilate and Herod in identifying His alleged crimes, the vicious display from religious leaders and the crowds calling for his death – all this before the beatings, the crown of thorns, and the carrying of the cross for miles. Once nailed to the cross, Jesus’ suffering escalates. Yet, He turns to the Father and focuses on the salvation of others until His last breath.
