Professor Lisi was the doctor/medical physician to Pope Puis XII. When Pope Puis XII died his body was preserved & Professor Lisi told the Press that he had been preserved in such a manner that his body would last indefintely without decaying. He then announced that this procedure was pretty much the same one that was used to preserve the body of Jesus Chist. 

The Vatican was in uproar. Lisi was banned by the Congregation of Cardinals from the whole of the Vatican state and the Government and Medical Association were alleged to have made Lisi's life very difficult at the instigation of Vatican officials. Professor Lisi resigned on October 20th, 1958.

  

But what a strange thing for a Doctor of the Vatican to say? Whereon earth would that statement even come from? No-one seems to ask that question. In 1958 no less? 

As Lull reported, as far back as 1309, the Vatican does indeed have many secrets. But the secret is also known by others. Lull said that the ‘true’ Templars possessed this secret –  ‘dangerous to the church’? Didn’t Lull tell us that among the many secrets that the Christians have there is one in particular that can threaten the whole edifice of the Papacy? What could be more dangerous to the barque of Saint Peter, which Professor Lisi found out to his cost, than suggest that the body of the historical Christ rests somewhere on this Earth?


The concept of Embalming the body in Christianity

According to Christianity, embalming the body involves the use of substances like myrrh in funerary practices, highlighting its significance in preserving the deceased. This practice is echoed in the traditions of ancient Egypt, exemplified by Joseph's request regarding his bones. These elements demonstrate the cultural and religious importance placed on the treatment of the dead, particularly in the context of eternal life beliefs within Christianity and other historical practices. Myrrh was employed for embalming the body, indicating its use in funerary practices, showcasing its importance in the preservation of the deceased.

Egypt is credited with being the land where embalming began. The process was practiced in Egypt was done for two reasons:

Religious

Greek historian Herodotus maintained that the Egyptians were the first people to believe in the immortality of the soul. They believed that the soul would never fully forsake the body as long as the body remained intact. Embalming was for the purpose of preserving the body so that the soul could return to it after the completion of the “circle of necessity.” This “circle of necessity” was a 3,000 year journey the soul was required to make before it could return to the body. At that time, the whole man would arise from the dead and live with the gods forever.

Sanitation

The writer Cassius maintained that embalming was developed to provide a solution to the problem of trying to bury the dead in the Nile valley which would be inundated on a frequent basis. The Egyptians apparently also noted that this unsanitary condition caused more deaths.

The Egyptian embalmers were members of the priesthood. 

The cheapest method was reserved for the poorest class of people, which made up about 80% of the Egyptian population. It basically consisted of immersion in a natron solution. Within a walled suburb known as the Necropolis (Literally, “City of the dead”) all death care activities took place. Within these walls resided all those involved in these activities including coffin makers, artists, and the embalmers. Also located here were the crypts and tombs.

• The Egyptians were not the only people to practice preservation of the dead.
• Ancient Ethiopian tribes preserved their dead in a manner similar to the Egyptians.
• Aboriginal inhabitants of the Canary Islands from 900 BC practiced mummification of their dead.
• Babylonians, Persians, and Syrians preserved their dead by placing them in jars of honey or wax. By depriving the bacteria in the body of air, decomposition was prevented.
• Peruvians practiced mummification 1000 years prior to being conquered by Spain in the early 16th century.
• Jewish preservation customs are simple. Embalming and cremation were generally not allowed, as they were seen as mutilation of the body. As described in the scriptures, preparation for burial consisted of wrapping the body and the application of oils and spices.
• The Greeks believed that the deceased must make a journey across the river Styx to the land of eternity. A coin was placed in the mouth of the deceased to pay passage over the river. A cake of honey was placed next to the body to appease the three headed dog, Cerebus, who guarded the entrance to Hades. Interment was delayed three days to prevent premature burial. Cremation came into practice around 300 BC.
• The Romans also did not practice embalming. The body was washed daily for seven days with hot water and oil. This delay also was to prevent premature burial. A group of slaves called pollinctores performed this process. Funeral processions were held at night to avoid defilement of the living. The procession was managed by a Designator, who functioned much like the modern day funeral director. Burial later gave way to cremation. At one point, cremation was forbidden within the gates of Rome because so many bodies were burned at once, causing smoke pollution.

The early Christians derived their burial customs from the Greeks, Romans, and Jews. They followed the strong Jewish tradition of burial with no embalming, upholding the sacred status of burial grounds.

It is in connection with this that the two instances we meet in the Old Testament are mentioned. (Genesis 50:2   Genesis 50:26) The embalmers first removed part of the brain through the nostrils, by means of a crooked iron, and destroyed the rest by injecting caustic drugs. An incision was then made along the flank with a sharp Ethiopian stone, and the whole of the intestines removed. The cavity was rinsed out with palm wine, and afterwards scoured with pounded perfumes. It was then filled with pure myrrh pounded, cassia and other aromatics, except frankincense. This done, the body was sewn up and steeped in natron (salf-petre) for seventy days. When the seventy days were accomplished, the embalmers washed the corpse and swathed it in bandages of linen, cut in strips and smeared with gum. They then gave it up to the relatives of the deceased, who provided for it a wooden case, made in the shape of a man, in which the dead was placed, and deposited in an erect position against the wall of the sepulchral chamber. Sometimes no incision was made in the body, nor were the intestines removed, but cedar-oil was injected into the stomach by the rectum. At others the oil was prevented from escaping until the end of the steeping process, when it was withdrawn, and carried off with it the stomach and intestines in a state of solution, while the flesh was consumed by the natron, and nothing was left but the skin and bones. The body in this state was returned to the relatives of the deceased.

Embalming of Jacob and Joseph. 

There are only two cases specifically called embalming in the Bible and both of these took place in Egypt. It was there that Jacob died, and after relating Joseph’s expression of sorrow over his father’s demise, the inspired Record states: “After that Joseph commanded his servants, the physicians, to embalm his father. So the physicians embalmed Israel, and they took fully forty days for him, for this many days they customarily take for the embalming, and the Egyptians continued to shed tears for him seventy days.” (Ge 50:2, 3) Joseph died at the age of 110 years, “and they had him embalmed, and he was put in a coffin in Egypt.” (Ge 50:26) In Jacob’s case the principal purpose apparently was preservation until his burial in the Promised Land. Joseph’s prominence may have been the reason in his case.—Ge 49:29-32; 50:13, 24, 25; Ex 13:18, 19; Jos 24:32.

According to Herodotus, Egyptian embalming methods included placing the corpse in natron for seventy days. Yet, when Jacob was embalmed by Egyptian physicians at a much earlier time, the Bible says “they took fully forty days for him, for this many days they customarily take for the embalming, and the Egyptians continued to shed tears for him seventy days.” (Ge 50:3) Scholars have made various efforts to reconcile Genesis 50:3 with the words of Herodotus. For one thing, the 40 days may not have included the time of the  body’s immersion in natron. However, it is quite possible that Herodotus simply erred in saying the dead body was placed in natron for 70 days. The later Greek historian Diodorus Siculus (of the first century B.C.E.) said that the Egyptian embalming process lasted over 30 days. (Diodorus of Sicily, I, 91, 5, 6) Of course, there may have been Egyptian embalming procedures that neither of these historians discussed, and it is possible that different time periods were involved in the embalming processes at various points in history.

Burial of Hebrews and Christians. 

The poor condition of human remains found in Palestinian tombs indicates that it was not the general Hebrew custom to embalm the dead (at least for long preservation in the manner of the Egyptians) and that early followers of Christ there did not embalm their deceased ones in an effort to preserve their bodies indefinitely. Faithful Hebrews and true Christians realized that the soul, whether that of a human or of an animal, dies and that the body returns to dust. (Ec 3:18-20; Eze 18:4) The fact that the Scriptures make such limited reference to embalming seems to be added proof that it was not a general practice among Hebrews and early Christians.The Scriptures, in telling about the burial of King Asa, state: “They laid him in the bed that had been filled with balsam oil and different sorts of ointment mixed in an ointment of special make. Further, they made an extraordinarily great funeral burning for him.” This was not cremation of the king, but a burning of spices. (2Ch 16:13, 14) And, if this use of an ointment may be considered a form of embalming at all, it was not the type practiced by the Egyptians.When Jesus Christ died, Nicodemus brought “a roll of myrrh and aloes, about a hundred pounds of it,” and it is stated: “So they took the body of Jesus and bound it up with bandages with the spices, just the way the Jews have the custom of preparing for burial.” (Joh 19:39, 40) However, this was not specifically called embalming, and it was not like embalming processes practiced by the Egyptians. It was the customary manner of preparing a body for burial, doubtless being similar to the way that Lazarus was prepared for interment. His case shows that the Jewish custom did not involve an elaborate embalming process designed to preserve the body for a long time, for when Jesus said, “Take the stone away,” Martha said: “Lord, by now he must smell, for it is four days.” She would not have expected that condition to exist if Lazarus had actually been embalmed. Lazarus’ feet and hands were bound with wrappings and “his countenance was bound about with a cloth,” but the intention evidently had not been that of preserving his body from putrefaction.—Joh 11:39, 44;

In the Gospel of John, embalming, or rather the preparation of Jesus' body for burial, is described as a process involving both Joseph of Arimathea and Nicodemus. Nicodemus brings a substantial quantity of myrrh and aloes, which are aromatic spices, to be used in the burial process. This is done according to Jewish burial customs, which included wrapping the body in linen cloths with the spices. Here's a more detailed breakdown:

• Nicodemus's Contribution: John 19:39 states that Nicodemus, who had previously visited Jesus at night, brought a mixture of myrrh and aloes, about seventy-five to one hundred pounds. This was a significant amount, indicating a lavish preparation for burial. 
• Jewish Burial Customs: The text emphasizes that the body was wrapped in linen cloths with the spices, "according to the Jewish burial custom". This suggests that while embalming as practiced in Egypt involved more extensive processes like removing organs, the Jewish custom focused on cleansing and anointing with spices to mask the odor of decay and honor the deceased. 
• Purpose of Spices: The spices, particularly myrrh and aloes, were used to both perfume the body and help preserve it, even if not to the same extent as full Egyptian embalming. 
• Significance: The extravagant use of spices by Nicodemus is interpreted as a sign of respect and honor for Jesus, possibly even foreshadowing his future role as the King of Kings. 
• 
  Mar 16:1 KJV And when the sabbath was past, Mary Magdalene, and Mary the mother of James, and Salome, had bought sweet spices, that they might come and anoint him.
  
  Luk 23:56 KJV And they returned, and prepared spices and ointments; and rested the sabbath day according to the commandment.
  
  Joh 19:39-40 KJV 39 And there came also Nicodemus, which at the first came to Jesus by night, and brought a mixture of myrrh and aloes, about an hundred pound weight. Then took they the body of Jesus, and wound it in linen clothes with the spices, as the manner of the Jews is to bury.

•  Jacob and Joseph were embalmed...
  
  And Joseph commanded his servants the physicians to embalm his father: and the physicians embalmed Israel. And forty days were fulfilled for him; for so are fulfilled the days of those which are embalmed: and the Egyptians mourned for him threescore and ten days.—Gen. 50:2,3
• So Joseph died, being an hundred and ten years old: and they embalmed him, and he was put in a coffin in Egypt.—Gen. 50:26
  
  It would appear Asa was also embalmed...
  
  And they buried him in his own sepulchres, which he had made for himself in the city of David, and laid him in the bed which was filled with sweet odours and divers kinds of spices prepared by the apothecaries' art: and they made a very great burning for him.—2 Chron. 16:14

I think the most we could say from scripture is that embalming included methods of a temporary preserving of a body. Certainly the methods in biblical times looked different than today’s method. As some have noted above it could include wrapping, spices, perfumes, and, in Jacob’s case, likely some additional Egyptian customs of preservation.
