We know that God chose the Feast Day of Passover for the time of Jesus’ Crucifixion as Jesus was the prophesied Passover Lamb.
“And on the first day of Unleavened Bread, when they sacrificed the Passover lamb, his disciples said to him, “Where will you have us go and prepare for you to eat the Passover?” Mark 14:12
“For Christ, our Passover lamb has been sacrificed. Let us, therefore, celebrate the festival, not with the old leaven, the leaven of malice and evil, but with the unleavened bread of sincerity and truth.” 1 Corinthians 5:7-8
Passover began at sundown and ended the following day at sundown. Jesus kept the Passover with his disciples and then was arrested later that night. After daybreak, the next morning he was questioned by Pontius Pilate, tortured, crucified, then hurriedly entombed just before the next sunset when the “high day” the Feast of Unleavened Bread began. It has been shown that in the year Jesus was crucified that the Passover Meal was eaten on a Tuesday night and that Wednesday sunset marked the beginning of the “high day”, the day of the Feast of Unleavened Bread.
Jesus, then, was crucified and entombed on Wednesday afternoon, Mark tells us that after the “high day” Sabbath, which that year began Wednesday evening at sundown and ended Thursday evening at sundown, the women bought spices to anoint Jesus’ body. Luke then tells us that the women prepared the spices on Friday and after that, they rested on the weekly Sabbath which was from Friday sundown to Saturday sundown. Matthew tells us that the women went to the tomb after the Sabbath.
Jesus was crucified and entombed on a Wednesday. Mary Magdalene went to the tomb on the first day of the week, Sunday, while it was still dark and she sees an empty tomb, so Jesus has risen before the start of the first day of the week as the day does not start until sunrise. As we are told Jesus was in the tomb for three days and three nights (Matthew 12:40) we can conclude that Jesus emerged from the tomb on Saturday at Sunset.
Let us worship God according to Biblical truth, not human tradition.
