I believe that Jesus was not crucified on Friday, but on Wednesday. Preachers have usually accepted the Roman Catholic teaching that He was crucified on Friday and have never investigated what the Bible teaches on that subject. All Bible evidence proves that Jesus was crucified on Wednesday, buried that night, and arose from the dead some time Saturday night, before sunrise Sunday morning. Remember that the Jewish day began at sundown and the night was counted a part of the following day.
Matthew 12:40 plainly says that Jesus would be three days and three nights in the heart of the earth, or the grave, like Jonah was three days and three nights in the whale's belly. If Jesus were crucified Friday and raised Saturday night, or before sunrise Sunday morning, He would have been in the grave one day and part of two nights. Certainly that would not fulfill His plain promise.
Many people have supposed that John 19:31 was evidence that Jesus was crucified on Friday since the Jews wished to take His body down before the Sabbath. Notice, however, that "that Sabbath day was an high day." It was not an ordinary weekly Sabbath, but an annual Sabbath, the one mentioned in Exodus 12:16. It was a day of rest, the first of seven days of eating of unleavened bread, the day on which the Passover lamb was eaten.
So Jesus was crucified on Wednesday, was taken down from the cross before sunset Wednesday (John 19:31)... Jesus stayed in the grave fully seventy-two hours, three days and three nights, and arose then some time Saturday night, that is, part of Sunday, the first day of the week which began at sundown. - John R.
