Krst (the 'K' is aspirated like 'Ch') is an Egyptian word meaning 'Burial'.
'Ancient Egypt' - "The change from bodily death to future life in spirit was acted as a transformation-scene in the mysteries of the resurrection. The mummy-Osiris was an effigy of death. The Sahu-mummy Amsu-Horus is an image of the glorious body into which Osiris transubstantiated to go forth from Sekhem as pure spirit. It is the mummy in this second stage that is of primary import. First of all the dead body was smeared over with unguents and thus glorified. During the process of anointing it was said, "O Asar (the deceased) the thick oil which is poured upon thee furnishes thy mouth with life" (Budge, "The Mummy", p. 163). It is also said that the anointing is done to give sight to the eyes, hearing to the ears, sense of smell to the nostrils and utterance to the mouth. To embalm the body thus was to karas it and the embalmment was a mode of making the typical Christ as the Anointed. Thus the mortal Horus was invested with the glory of the only God-begotten Son. Now this making of the Krst, or mummy-Christ, after the Egyptian fashion is apparent in the Gospels. When the woman brings the alabaster cruse of precious ointment to the house of Simon and pours it on the head of Jesus he says, "In that she poured this ointment upon my body, she did it to prepare me for my burial" (Matthew 26:12). She was making the Christ as the anointed-mummy previous to interment. After the description of the crucifixion it is said that Nicodemus came and brought a "mixture of myrrh and aloes, about a hundred pound" and "they took the body of Jesus and bound it in linen cloths with the spices as the custom of the Jews is to bury" (John 19:39,40). This again denotes the making of the Karest-mummy=the Christ. Moreover, it is the dead mummy in one version and it is the living body in the other which is anointed, just as Horus was anointed with the exceedingly precious Antu ointment, or oil, that was poured upon his head and face to represent his glory." (Note the Hindu God Krishna whose story is the same as that of Horus, also takes his name from the Sanskrit root 'krst' meaning 'Christ' and was formerly spelled 'Christ-Na')
Tertullian claims that the name of the Christians came from the unction received by Jesus Christ. This is in perfect keeping with the derivation of the typical Christ from the mummy which was anointed so abundantly with oil in its embalmment. It is said of the woman who anointed Jesus in Bethany," in that she poured the ointment upon my body, she did it to prepare me for my burial " (Matthew 26:12). She was preparing the mummy after the manner of Anup the embalmer, who prepared Osiris for his burial and resurrection. But it was only as a dead mummy and not a living man that the gnostic Jesus could have been embalmed for burial.
We now proceed to show that Christ the anointed is none other than the Osiris-karast, and that the karast mummy risen to its feet as Osiris-sahu was the prototypal Christ. Unhappily, these demonstrations cannot be made without a wearisome mass of detail. And we are bound for the bottom this time. Dr. Budge, in his book on the mummy, tells his readers that the Egyptian word for mummy is ges, which signifies to wrap up in bandages. But he does not point out that ges or kes, to embalm the corpse or make the mummy, is a reduced or abraded form of an earlier word, karas (whence krst for the mummy). The original word written in hieroglyphics is, krst, whence kas, to embalm, to bandage, to knot, to make the mummy or karast (Birch, Dictionary of the Hieroglyphics, pp. 415-416; Champollion, Gram. Egyptienne, 86). The word krs denotes the embalmment of the mummy, and the krst, as the mummy, was made in the process of preparation by purifying, anointing, and embalming. To karas the dead body was to embalm it, to bandage it, to make the mummy. The mummy was the Osirian Corpus Christi, prepared for burial as the laid-out dead, the karast by name. When raised to its feet, it was the risen mummy, or sahu. The place of embalmment was likewise the krs. Thus the process of making the mummy was to karas, the place in which it was laid is the karas, and the product was the krst, whose image is the upright mummy = the risen Christ. Hence the name of the Christ, Christos in Greek, Chrestus in Latin, for the anointed, was derived, as the present writer previously suggested, from the Egyptian word krst. Karas also signifies the burial-place, and the word modifies into Kâs or Châs. Kâsu the burial place "was a name of the 14th Nome in Upper Egypt. A god Kâs is mentioned three or four times in the Book of the Dead, the god Kâs who is in the Tuat" ( ch. 40). This was a title of the mummy Osiris in the funerary dwelling. In one passage Kâs is described as the deliverer or saviour from all mortal needs. In "the chapter of raising the body" (178) it is said of the deceased that he had been hungry and thirsty (on earth), but he will (never hunger or thirst any more, "for Kâs delivers him" and does away with wants like these. That is, in the resurrection. Here the name of the god Osiris-Kâs written at full is Osiris the Karast - the Egyptian Christ. Not only is the risen mummy or sahu called the karast, Osiris as lord of the bier is the Neb-karast equivalent to the later Christ the Lord, and the lord of the bier is god of the resurrection from the house of death. The karast is literally the god or person who has been mummified, embalmed, and anointed or christified. Anup the baptizer and embalmer of the dead for the new life was the preparer of the karast-mummy. As John The Baptist is the founder of the Christ in baptism, so Anup was the christifier of the mortal Horus, he on whom the holy ghost descended as a bird when the Osiris made his transformation in the marriage mystery of Tat tu (Rit., ch. 17). We read in the funeral texts of Anup - being "Suten tu hetep, Anup, neb tser khent neter ta krast-ef em set" (Birch, Funereal Text 4th Dynasty). "Suten hept tu Anup tep-tuf khent neter ha am ut neb tser krast ef em as-ef en kar neter em set Amenta" (Birch, Funereal Stele of Ra-Khepr-Ka, 12th Dynasty). Anup gives embalmment, krast; he is lord over the place of embalmment, the kras ; the lord of embalming (krast), who, so to say, makes the "krast". The process of embalmment is to make the mummy. This was a type of immortality or rising again. Osiris is krast, or embalmed and mummified for the resurrection. Passage into life and light is made for the karast-dead through the embalmment of the good Osiris (Rit., ch. 162) - that is, through his being karast as the mummy type. Thus the Egyptian krast was the pre-Christian Christ, and the pictures in the Roman Catacombs preserve the proof. The passing of the karast into the Christ is depicted in the gnostic iconography. It is in the form of a child bound up in the swathings of a diminutive Egyptian mummy, with the halo and cross of the four quarters round its head, which show its solar origin. It is the divine infant which has the head of Ra in the Ritual who says, "I am the babe; I renew myself, and I grow young again" (chs. 42 and 43). The karast mummy is the type of resurrection in the Roman Catacombs because the karast was the prototypal Christ. It is the Egyptian karast as thing and word that supplied and will explain the Greek Christ, Christos, Krstos, or Latin Chrestus and account for the Corpus Christi, the anointed, the Saviour, doctrinally, typically, actually in every way except historically, and of that the karast, Krstos, or Christ is entirely independent. "Henceforth", said a dignitary of the Church of England the other day, "Christianity has done with the metaphysical Christ". But there is no physical Christ except the karast mummy, which was Osiris when laid out and lying down in death, and Horus of the resurrection standing up as Amsu risen from the sepulchre, having the whip hand over all the powers of darkness and the adversaries of his father.
Say what you will or believe what you may, there is no other origin for Christ the anointed than for Horus the karast or anointed son of god the father. There is no other origin for a Messiah as the anointed than for the Masu or anointed. Finally, then, the mystery of the mummy is the mystery of the Christ. As Christian, it is allowed to be for ever inexplicable. As Osirian, the mystery can be explained. It is one of the mysteries of Amenta, with a more primitive origin in the rites of totemism.
We now claim sufficient warrant for affirming that Christ the anointed is a mystical figure which originated as the Egyptian mummy in the twofold character of Osiris in his death and in his resurrection; as Osiris, or mortal Horus, the karast; and Osiris-sahu, or Horus divinized as the anointed son. The Christ or karast still continues to be made when the sacrament of extreme unction is administered to the dying as a Roman Catholic rite. Though but a shadow of the primitive reality, it perpetuates the "sacred mystery" of converting the corpse into the sahu, the transubstantiation of the inert Osiris by descent of Ra; the mortal Horus, child of the mother, into Horus the anointed son of god the father. "Extreme unction", the seventh of the holy sacraments, is indeed a Christian rite.
