"And they crucified Him,"
Mark 15:24a
(The following is taken from Pastor Dave Gruzik's Commentaries on the Bible.)
The Bible spares us the gory descriptions of Jesus' agony, simply stating then they crucified Him. This is because everyone in Matthew's day was well acquainted with the terror of crucifixion, and because the greater aspect of Jesus' suffering was spiritual, not physical
In 1986, Dr. William Edwards wrote a remarkable article in the prestigious Journal of the American Medical Association titled "On the Physical Death of Jesus Christ." Following are some of the observations of Dr. Edwards and his associates. The quotations belong to the article, and much of the other text is paraphrased from the article.
What was it like to be crucified? In days the New Testament was first written, the practice needed no explanation. But we would do well to appreciate just what happened at a crucifixion. "Although the Romans did not invent crucifixion, they perfected it as a form of torture and capital punishment that was designed to produce a slow death with maximum pain and suffering."
The victim's back would first be torn open by the scourging, then the clotting blood would be ripped open again when the clothes were torn off the victim. When thrown on the ground to fix his hands to the crossbeam, the wounds would again be torn open and contaminated with dirt. Then, as he hung on the cross, with each breath, the painful wounds on the back would scrape against the rough wood of the upright beam and be further aggravated
Driving the nail through the wrists would sever the large median nerve - this stimulated nerve would produce excruciating bolts of fiery pain in both arms, and could result in a claw-like grip in the victim's hands.
Beyond the excruciating pain, the major effect of crucifixion inhibited normal breathing. The weight of the body, pulling down on the arms and shoulders, would tend to fix the respiratory muscles in an inhalation state, and hinder exhalation. The lack of adequate respiration would result in severe muscle cramps, which would hinder breathing even further. To get a good breath, one would have to push against the feet, and flex the elbows, pulling from the shoulders. Putting the weight of the body on the feet would produce searing pain, and flexing of the elbows would twist the hands hanging on the nails. Lifting the body for a breath would also painfully scrape the back against the rough wooden post. Each effort to get a proper breath would be agonizing, exhausting, and lead to a sooner death.
"Not uncommonly, insects would light upon or burrow into the open wounds or the eyes, ears, and nose of the dying and helpless victim, and birds of prey would tear at these sites. Moreover, it was customary to leave the corpse on the cross to be devoured by predatory animals."
Death from crucifixion could come from many sources: acute shock from blood loss; being too exhausted to breathe any longer; dehydration; stress-induced heart attack, or congestive heart failure leading to a cardiac rupture. If the victim did not die quickly enough, the legs would be broken, and the victim would soon be unable to breathe.
How bad was crucifixion? We get our English word excruciating from the Roman word "out of the cross." "Consider how heinous sin must be in the sight of God, when it requires such a sacrifice!" (Commentator Adam Clarke)
The most significant thing about Jesus' sufferings was that He was not, in any sense, the victim of circumstances. He was in control. Jesus said of His life in John 10:18, no one takes it from Me, but I lay it down of Myself. It is terrible to be forced to endure such torture, but to freely choose it out of love is remarkable. Can we ever doubt God's love for us again? Has He not gone to the most extreme length to demonstrate it?
