It is entirely possible that Jesus did actually survive his crucifixion that passover evening.
A favored Roman practice of execution, crucifixion was dictated by very strict procedure. Following a good beating or flogging by Roman soldiers. One would be laid out on the ground and a wooden beam would be affixed to the outstretched arms, across the shoulders and the back of the neck. The beam was usually held in place by a goat-leather rope. Occasionally, however, nails would be used to firmly secure the criminal to the beam. But nails were very expensive and not used as often as readily available goat-leather.
After being secured to the bean, a Roman solider would have you pull yourself up on your feet. If this proved too much for you, he would nudge you along with a crack of the whip or a kick on the backside, just so you know he meant business. Once standing, it was now time to make your way, step-by-step to the crucifixion area.
With a flogging, leather ropes affixing you firmly to a heavy beam, walking bare-foot in 100 degree weather and lets not forget the loss of blood, you would be exhausted, thirsty and sore. But now comes the raising of the beam you're hanging from to a pole. We do not know how high these poles were, they could have been only six or so feet up off the ground. It would be a brutal, exquisite pain to suffer. If the Roman soldiers left you to hang there by your hands, the pressure to one's lungs would cause the lungs to collapse or breathing would cease altogether, and welcoming death would follow. However, if the architects of pain and torture strung your ankles to the cross, you had a chance of survival. By pressing down on one's feet, you could relieve some of the pressure on the chest and lungs, not only prolonging your suffering, but your odds, too. But, a healthy young man in good shape could withstand and survive the punishment.
Having had come this far in the process of crucifixion, Jesus would more than likely have passed out at this point. Hanging limply on the cross, he would indeed appear to be dead. And the timing could not have been more in his favor it he had planned it to be. Let us not forget that it is the Passover, and no self-respecting Jew would be caught actually doing anything after sunset. A Roman law of the day cited that no one crucified could be buried by his family. And guards always stood sentry to make sure that family members did not make off with the body.
The Sanhedrin, a Council of Elders ruling the Judaic city of Jerusalem had in it's membership a very wealthy man named Joseph of Arimathea. Joseph as a tin and bronze merchant who owned mines in Brittan and India, as well as his own vast fleet of merchant sailing ships. Joseph, being an old man of great means has already commissioned his own tomb to be carved in a niche. He was also a personal and business acquaintance of Pilate's. When Joseph asked Pilate for the body of Jesus, Pilate allows him to take the body of Jesus and have it removed. He wants nothing more to do with this. Night is approaching, he is weary and wants this day to be over.
Joseph has Jesus removed from the cross and taken to his tomb in the garden. Once the servants of Joseph lay Jesus on the stone slab, the scenario changes. The women of Jesus' family are Mary, his mom; Simeon, his baby brother; Mary Salome, his aunt; and Mary of Magdala, his wife. (Oh, stop it! I know what you're thinking! But remember this, Jesus was a Rabbi, right? Show me a single Rabbi, eh?)
These ladies get right to work, not preserving Jesus for entombing with oils and herbs, but healing him, with oils and herbs. Cleaning his scourged and bloody battered body with the soothing oils and aloes, applying ointments and herbals to ward off infection, then covering him with a clean linen cloth, that he may rest and recover. Emotionally and physically drained, the ladies curl up on the floor of the tiny tomb and sleep for the first time in a couple nights.
Three days later, Jesus awakens. He is stiff, sore and thirsty. The entrance to the tomb is slightly ajar, and fresh air and light flow in. The air smells good compared to the stuffy little room. He steps outside into the April sunshine. And coming upon Mary, his wife, tired and cranky and crying in the garden, he asks her why she's crying. If they had cast iron frying pans back then she probably would have it him with one. Why do you think I'm crying? You're better!
Does that not make more sense to you? Does that explanation sound more plausible? Rather than dying an excruciatingly agonizing death up on the cross, Jesus passed out, possibly even became temporarily comatose due to exhaustion, thirst, low blood sugar and high blood pressure (why do you suppose he sweated blood in the Garden at Gethsemane? HPB breaking little veins and capillaries in his face and neck), not to mention the Roman's beating the hell out of him. If you take a fresh approach to the Passion story, and look at it in a 'What most likely happened?' rather than the Jeffrey Hunter surgically-sterile movie version, it makes absolute sense.
By that, taking a big realistic and a little scientific approach to the matter of crucifixion, is actually twofold. Yes, poor Jesus was technically crucified (and there are sadly no writing's to prove or record it) but NO, he did not die from being crucified. History truly does not know how or when this Rabbi messenger did pass away, only that's he has remained in our hearts ever since.
