Osiris was considered not only a merciful judge of the dead in the afterlife, but also the underworld agency that granted all life, including sprouting vegetation and the fertile flooding of the Nile River. He was described as the "Lord of love",[8] "He Who is Permanently Benign and Youthful"[9] and the "Lord of Silence".[10] The Kings of Egypt were associated with Osiris in death — as Osiris rose from the dead they would, in union with him, inherit eternal life through a process of imitative magic. By the New Kingdom all people, not just pharaohs, were believed to be associated with Osiris at death, if they incurred the costs of the assimilation rituals.[11]

Through the hope of new life after death, Osiris began to be associated with the cycles observed in nature, in particular vegetation and the annual flooding of the Nile, through his links with the heliacal rising of Orion and Sirius at the start of the new year.[9] Osiris was widely worshipped as Lord of the Dead until the suppression of the Egyptian religion during the Christian era.[12][13]

And Horus, the Egyptian Christ, who is identical with the Jesus of the Gospels in some one hundred and eighty particulars, performed at Anu a great miracle. He raised his father Osiris from the dead, calling unto him in the cave to rise and come forth. Anu, as we have seen, became Bethany of the Gospels; and it was at Bethany that Jesus raised Lazarus from death! And who was Lazarus? Here the greatest of all the marvels in this chain of comparative data unfolds under our eyes. According to Budge and other eminent Egyptologists the ancient designation of Osiris was ASAR. But the Egyptians invariably expressed reverence for deity by prefixing the definite article "the" to the names of their Gods. Just as Christians say, or should say, the Christ, they said: the Osiris. It will be found that the article connoted deity in ancient usage. Our definite article, "the" is the root of the Greek word theos, God; the Spanish article, masculine, "el," is the Hebrew word for God; and the Greek masculine article, "ho," is a Chinese word for deity. To say the Osiris was equivalent to saying Lord Osiris. When the Hebrews took up the Egyptian phrases and names they converted the name of "the Osiris" or "Lord Osiris" directly into their own vernacular, and the result was "El-Asar." Later on the Romans, speaking Latin, took up the same material that had come down from revered Egyptian sources and to "El-Asar" they added the common Latin termination of the second declension masculine nouns, in which most men’s names ended, namely, "-us"; and the result was now "El-Asar-us." In time the initial "E" wore off, as the scholars phrase it, and the "s" in Asar changed into its sister letter "z," leaving us holding in our hands the Lazarus whom Jesus raised at Bethany! To evidence that this derivation is not a fanciful invention or sheer coincidence the Biblical names of High Priests may be cited. We find one with the name of El(e)azar and another by name Azar-iah, "iah" or "jah" being suffixes of great deific connotation, matching "el." And so we are faced with the irrefutable evidence of Comparative Religion that Jesus’ raising of Lazarus at Bethany is but a rescript of the old Egyptian dramatic mystery in which Horus, the Christ, raised his "dead" father Osiris, or El-Asar-us from the grave. And the Egyptian recital was in the papyri perhaps 5000 years B.C.

The Ritual text (Ch. 170) calls to the glorified soul: "Hail, Osiris, thou art born twice!" Again: "Stand up living forever. Thy son Horus reconstituted thee. Arise on thy bed and come forth! Come! Come forth!" They call him to come forth "like a god" "from the mysterious cave."
