Each year, Cahleen Shrier, PhD, professor in the Department of Biology and Chemistry, presents a special lecture on the science of Christ’s crucifixion. She details the physiological processes a typical crucified victim underwent and teaches her students to see Christ’s death on the cross with new understanding. The exact events in this scenario may not have happened in Jesus’ specific case, but the account is based on historical documentation of crucifixion procedures used during that time period. Please be aware that the following is of a realistic and graphic nature.
It is important to understand from the beginning that Jesus would have been in excellent physical condition. As a carpenter by trade, He participated in physical labor. In addition, He spent much of His ministry traveling on foot across the countryside. His stamina and strength were, most likely, very well developed. With that in mind, it is clear just how much He suffered: If this torture could break a man in such good shape, it must have been a horrific experience.
Matthew 26:36-46, Mark 14:37-42, Luke 22:39-44
After the Passover celebration, Jesus takes His disciples to Gethsemene to pray. During His anxious prayer about the events to come, Jesus sweats drops of blood. There is a rare medical condition called hematohidrosis, during which the capillary blood vessels that feed the sweat glands break down. Blood released from the vessels mixes with the sweat; therefore, the body sweats drops of blood. This condition results from mental anguish or high anxiety, a state Jesus expresses by praying “my soul is deeply grieved to the point of death” (Matthew 26:38). Hematohidrosis makes the skin tender, so Jesus’ physical condition worsens slightly.
Matthew 26:67-75, Mark 14:61-72, Luke 22:54-23:25, John 18:16-27
Traveling from Pilate to Herod and back again, Jesus walks approximately two and a half miles. He has not slept, and He has been mocked and beaten (Luke 22:63-65). In addition, His skin remains tender from the hematohidrosis. His physical condition worsens.
Matthew 27:26-32, Mark 15:15-21, Luke 23:25-26, John 19:1-28
Pilate orders Jesus to be flogged as required by Roman law before crucifixion Traditionally, the accused stood naked, and the flogging covered the area from the shoulders down to the upper legs. The whip consisted of several strips of leather. In the middle of the strips were metal balls that hit the skin, causing deep bruising. In addition, sheep bone was attached to the tips of each strip.
When the bone makes contact with Jesus’ skin, it digs into His muscles, tearing out chunks of flesh and exposing the bone beneath. The flogging leaves the skin on Jesus’ back in long ribbons. By this point, He has lost a great volume of blood which causes His blood pressure to fall and puts Him into shock. The human body attempts to remedy imbalances such as decreased blood volume, so Jesus’ thirst is His body’s natural response to His suffering (John 19:28). If He would have drank water, His blood volume would have increased.
Roman soldiers place a crown of thorns on Jesus’ head and a robe on His back (Matthew 27:28-29). The robe helps the blood clot (similar to putting a piece of tissue on a cut from shaving) to prevent Jesus from sustaining more blood loss. As they hit Jesus in the head (Matthew 27:30), the thorns from the crown push into the skin and He begins bleeding profusely. The thorns also cause damage to the nerve that supplies the face, causing intense pain down His face and neck. As they mock Him, the soldiers also belittle Jesus by spitting on Him (Matthew 27:30). They rip the robe off Jesus’ back and the bleeding starts afresh.
Jesus’ physical condition becomes critical. Due to severe blood loss without replacement, Jesus is undoubtedly in shock. As such, He is unable to carry the cross and Simon of Cyrene executes this task (Matthew 27:32).
Matthew 27:33-56, Mark 15:22-41, Luke 23:27-49, John 19:17-37
Crucifixion was invented by the Persians between 300-400 B.C. It is quite possibly the most painful death ever invented by humankind. The English language derives the word “excruciating” from crucifixion, acknowledging it as a form of slow, painful suffering.1 Its punishment was reserved for slaves, foreigners, revolutionaries, and the vilest of criminals. Victims were nailed to a cross; however, Jesus’ cross was probably not the Latin cross, but rather a Tau cross (T). The vertical piece (the stipes) remains in the ground permanently. The accused carries only the horizontal piece (the patibulum) up the hill. Atop the patibulum lies a sign (the titulus), indicating that a formal trial occurred for a violation of the law. In Jesus’ case, this reads “This is the King of the Jews” (Luke 23:38).
