Of the many aspects of this initial suffering, the one of greatest physiological interest is the bloody sweat. It is interesting that St. Luke, the physician, is the only one to mention this. He says, “And being in agony, He prayed the longer. And His sweat became as drops of blood, trickling down upon the ground.” Every ruse (trick) imaginable has been used by modern scholars to explain away this description, apparently under the mistaken impression that this just doesn’t happen. A great deal of effort could have been saved had the doubters consulted the medical literature. Though very rare, the phenomenon of Hematidrosis, or bloody sweat, is well documented. Under great emotional stress of the kind our Lord suffered, tiny capillaries in the sweat glands can break, thus mixing blood with sweat. This process might well have produced marked weakness and possible shock. ...
...Jesus was next brought before the Sanhedrin and Caiphus, the High Priest; it is here that the first physical trauma was inflicted. A soldier struck Jesus across the face for remaining silent when questioned by Caiphus...
...In the early morning, battered and bruised, dehydrated, and exhausted from a sleepless night, Jesus is taken across the Praetorium of the Fortress Antonia, the seat of government of the Procurator of Judea, Pontius Pilate...
...but the Jews had an ancient law prohibiting more than forty lashes. The Roman legionnaire steps forward with the flagrum (or flagellum) in his hand. This is a short whip consisting of several heavy, leather thongs with two small balls of lead attached near the ends of each. The heavy whip is brought down with full force again and again across Jesus’ shoulders, back, and legs.
At first the thongs cut through the skin only. Then, as the blows continue, they cut deeper into the subcutaneous tissues, producing first an oozing of blood from the capillaries and veins of the skin, and finally spurting arterial bleeding from vessels in the underlying muscles. The small balls of lead first produce large, deep bruises which are broken open by subsequent blows. Finally the skin of the back is hanging in long ribbons and the entire area is an unrecognizable mass of torn, bleeding tissue...
...Flexible branches covered with long thorns (commonly used in bundles for firewood) are plaited into the shape of a crown and this is pressed into His scalp. Again there is copious bleeding, the scalp being one of the most vascular areas of the body. ..
...In spite of His efforts to walk erect, the weight of the heavy wooden beam, together with the shock produced by copious blood loss, is too much. He stumbles and falls. The rough wood of the beam gouges into the lacerated skin and muscles of the shoulders...
...The left foot is now pressed backward against the right foot, and with both feet extended, toes down, a nail is driven through the arch of each, leaving the knees moderately flexed. The Victim is now crucified. As He slowly sags down with more weight on the nails in the wrists, excruciating pain shoots along the fingers and up the arms to explode in the brain — the nails in the wrists are putting pressure on the median nerves.
As He pushes Himself upward to avoid this stretching torment, He places His full weight on the nail through His feet. Again there is the searing agony of the nail tearing through the nerves between the metatarsal bones of the feet. At this point, as the arms fatigue, great waves of cramps sweep over the muscles, knotting them in deep, relentless, throbbing pain. With these cramps comes the inability to push Himself upward. Hanging by his arms, the pectoral muscles are paralyzed and the intercostal muscles are unable to act. Air can be drawn into the lungs, but cannot be exhaled. Jesus fights to raise Himself in order to get even one short breath. Finally, carbon dioxide builds up in the lungs and in the blood stream and the cramps partially subside. Spasmodically, he is able to push Himself upward to exhale and bring in the life-giving oxygen....
...Jesus experienced hours of limitless pain, cycles of twisting, joint-rending cramps, intermittent partial asphyxiation, searing pain where tissue is torn from His lacerated back as He moves up and down against the rough timber. Then another agony begins -- a terrible crushing pain deep in the chest as the pericardium slowly fills with serum and begins to compress the heart...
... The 34th verse of the 19th chapter of the Gospel according to St. John reports: “And immediately there came out blood and water.” That is, there was an escape of water fluid from the sac surrounding the heart, giving postmortem evidence that Our Lord died not the usual crucifixion death by suffocation, but of heart failure (a broken heart) due to shock and constriction of the heart by fluid in the pericardium. ...
