Swoon hypothesis

The swoon hypothesis is any of a number of ideas that aim to explain the resurrection of Jesus, proposing that Jesus did not die on the cross, but merely fell unconscious ("swooned"), and was later revived in the tomb in the same mortal body. This 200-year-old hypothesis is still the subject of debate in popular circles but the scholarly literature considers it uncontroversial that Jesus died during the process of crucifixion.
18th and 19th centuries.
Early proponents of this theory include German Karl Friedrich Bahrdt, who suggested in around 1780 that Jesus deliberately feigned his death, using drugs provided by the physician Luke to appear as a spiritual messiah and get Israel to abandon the idea of a political messiah. In this interpretation of the events described in the Gospels, Jesus was resuscitated by Joseph of Arimathea, with whom he shared a connection through a secret order of the Essenes — a group that appear in many of the "swoon" theories.
Around 1800, Karl Venturini proposed that a group of supporters dressed in white — who were, with Jesus, members of a "secret society" — had not expected him to survive the crucifixion, but heard groaning from inside the tomb, where Jesus had regained consciousness in the cool, damp air. They then frightened away the guards and rescued him.
A third rationalist theologian, Heinrich Paulus, wrote in works from 1802 onwards that he believed that Jesus had fallen into a temporary coma and somehow revived without help in the tomb. He was critical of the vision hypothesis and argued that the disciples must have believed that God had resurrected Jesus. Friedrich Schleiermacher endorsed a form of Paulus' theory in the early 1830s.
Mirza Ghulam Ahmad, the founder of the Ahmadiyya Muslim Movement, proposed a theory in his 1899 book "Jesus in India" that Jesus traveled to India after surviving the crucifixion.
20th century.
Though abandoned by modern scholars as a fringe theory, the hypothesis has remained popular in various works of pseudohistory, such as Michael Baigent, Richard Leigh and Henry Lincoln's 1982 book "Holy Blood, Holy Grail", Barbara Thiering's 1992 "Jesus and the Riddle of the Dead Sea Scrolls", and Michael Baigent's 2006 "The Jesus Papers". A fuller list of proponents of various "swoon theories":
In contrast, modern skeptics of swooning claims, such as diagnostician Dr. Alexander Metherell, assert that Jesus having survived crucifixion is "impossible" and "a fanciful theory without any possible basis in fact." Further example may be found in a thorough analysis conducted by the Journal of the American Medical Association, which concluded Jesus was very probably dead even prior to the spear being thrust into his side, and that any swoon hypothesis is entirely irreconcilable with contemporary medical science.
Islamic perspective.
Inadvertently, the biggest proponent of the swoon hypothesis in the modern era would likely be Muslim preacher Ahmed Deedat of South Africa, whose book "Crucifixion or Cruci-fiction" has been widely printed and distributed all over the Muslim world. He also wrote several books on this topic. He takes a critical look at the events in the four Gospels and theorizes an alternative scenario of what really happened, a scenario very similar to the swoon hypothesis.
Another contemporary Muslim scholar, Zakir Naik, also used these theories in a debate with Pastor Ruknuddin Henry Pio. 
The Islamic position on the subject of crucifixion is highlighted in verse of the Qur'an: "and for their saying, 'We killed the Messiah, Jesus, son of Mary, the messenger of Allah.' But they did not kill him nor did they crucify him, but it was made to appear to them so. Even those who dispute about it are in doubt; they have no certain knowledge other than conjecture. But they certainly did not kill him.".
Ahmadiyya perspective.
According to the late 19th century writings of Mirza Ghulam Ahmad, the founder of the Ahmadiyya movement, the theological basis of the Ahmadi belief is that Jesus was only "in a swoon" when he was taken down from the cross. Ahmad argued that when Jesus was taken down from the cross, he had lapsed into a state similar to Jonah's state of "swoon" in the belly of a fish. Mirza Ghulam Ahmad interpreted the phrase in Deuteronomy 21:23: "kī qilelat Elohim taluy", "… for a hanged man is the curse of God", as suggesting that "God would never allow one of His true prophets to be brutally killed in such a degrading manner as crucifixion". Following his ordeal, Jesus was cured of his wounds with a special 'ointment of Jesus' ("marham-i ʿIsā").".
Rajneesh movement.
Indian Philosopher Rajneesh has also argued that Jesus survived the Crucifixion and his argument is similar to the swoon hypothesis.
Supporting arguments.
Short stay of Jesus on the cross.
It was uncommon for a crucified healthy adult to die in the time described by the Gospels; the Gospel of Mark reports that Jesus was crucified at nine in the morning and died at three in the afternoon, or six hours after the crucifixion. Pilate was surprised to hear that Jesus had died so soon (Mk 15:44). The average time of suffering before death by crucifixion is claimed by some to have been observed to be 2–4 days; moreover, the 17th century philosopher Justus Lipsius claims that victims of crucifixion survive for as long as 9 days.
However, the precise duration of crucifixion until death occurs would depend on the type of crucifixion, the amount of blood loss already inflicted from the flogging and scourging performed beforehand, and the general physical health of the individual being executed. Also, if a spear was thrust into the exposed side of Jesus as expressly recorded in the Gospel of John account, such an event could have inevitably contributed to an extremely rapid death absent immediate, sophisticated medical attention.
Lack of eyewitness accounts of Jesus' dead body.
Jesus' body, as per the Gospel narratives, is not seen by eyewitnesses nor reported upon as such after his death. No elaborate funeral arrangements and no public viewing of the corpse are recorded to have taken place. Jesus' body is removed from the cross into the custody of his executioner, Pontius Pilate. Soon thereafter, Jesus' body is given by Pilate to a member of the Jewish council, Joseph of Arimathea, a wealthy man and a secret follower of Jesus. Joseph of Arimathea, along with a Pharisee named Nicodemus, wrap Jesus' body in linen and transport the body to a nearby, stone-covered burial chamber.
Jewish religious law (halacha) forbids embalming, and therefore Jews generally bury their dead as soon as possible: "Jewish burials take place as quickly as possible, following a principle of honoring the dead ("k'vod hamet").
The transfer of Jesus' body by the local authorities into the hands of a rich influential follower and execution of a quick burial lend support to the swoon hypothesis, allowing a swooned Jesus to be removed from the cross, quickly hidden away from public scrutiny with room to recover from his ordeal in an above ground burial chamber on private property.
Counter-arguments.
Jesus' state of health.
The swoon hypothesis has been criticized by many, including medical experts who, based on the account given in the New Testament, conclude that Jesus was definitively dead when removed from the cross. Many others consider it unlikely that Jesus would be capable of inspiring faith in those who saw him after barely surviving a crucifixion, including the 19th century rationalist theologian David Strauss, who wrote: "It is impossible that a being who had stolen half dead out of the sepulchre, who crept about weak and ill and wanting medical treatment... could have given the disciples the impression that he was a conqueror over death and the grave, the Prince of life: an impression that lay at the bottom of their future ministry."
Medical arguments.
Medical authorities W. D. Edwards, W. J. Gabel and F. E. Hosmer offered the following analysis in regard to the New Testament Greek and the medical data: Jesus of Nazareth underwent Jewish and Roman trials, was flogged, and was sentenced to death by crucifixion. The scourging produced deep stripelike lacerations and appreciable blood loss, and it probably set the stage for hypovolemic shock, as evidenced by the fact that Jesus was too weakened to carry the crossbar (patibulum) to Golgotha. At the site of crucifixion, his wrists were nailed to the patibulum and, after the patibulum was lifted onto the upright post (stipes), his feet were nailed to the stipes. The major pathophysiologic effect of crucifixion was an interference with normal respirations. Accordingly, death resulted primarily from hypovolemic shock and exhaustion asphyxia. Jesus' death was ensured by the thrust of a soldier's spear into his side. Modern medical interpretation of the historical evidence indicates that Jesus was dead when taken down from the cross. 
Forensic pathologist Frederick T. Zugibe has described the swoon hypothesis as completely unfounded and contradicted by medical evidence. According to Zugibe the long spikes that penetrated Jesus' feet would have caused massive swelling and severe pain beginning in the first hour on the cross and over the next few days would have been massively swollen and infected beyond any immediate healing capability. Jesus would not have been able to stand or walk on his feet for at least a month or longer. Zugibe argued that it was not possible for Jesus to have survived his crucifixion and no drugs or medications of the time would have been able to stop the pain Jesus had experienced or put him into a deep sleep to feign death.
