_Diabolus._ This name designates him more as to his ruling and authority than to the elements of his character. We have noticed already the meaning of Devil, but from the original word we get more explicit meaning as to his rank of authority. As Lucifer we do not know his ruling rank, but in his lost estate he ranks as Commander-in-chief. Whatever we may say of him, the prefix, "arch," designating his angel rank, can be logically attached: archspoiler--arch-deceiver--archaccuser--archslanderer, etc. However, if accurately defined, diabolus means _Calumniator_--archcalumniator; a propagator of calumny. Acting in the capacity of calumniator, he seeks out and defames the innocent. He sends out a million rumours daily which would be, if tangible, cases for libel in any court. _Demonia._ A demon--a fallen angel--evil spirit, an imp. Literally, a _shade_--a dark spot, moving as noiselessly and rapidly as a shadow. The many references in the New Testament to "devil," and "devils," should always be _demons_; the great multitude, so often found in one place, come from the innumerable concourse which constitute the "powers of darkness." Shadow spirits, men and women who are controlled by these dark, shadowy imps, "love darkness rather than light because their deeds are evil." The transformation, as we learned, which took place with Lucifer was just as great and radical with his angel followers; the difference was only that of degree of rank. _Abaddon-Apollyon._ We have coupled the Hebrew and Greek names together, as each means exactly the same. We call the attention of the reader to the variety of names, all of which are so nearly alike, but convey a significant difference. Abaddon-Apollyon means _destroyer_. He has been discussed as a "spoiler," but one who destroys carries the work farther than the spoiler. As Abaddon or Apollyon he is the king of the abyss, or "Bottomless Pit," and when he appears it is with purpose and equipment for destruction. Just as God sent the "Destroying Angel" throughout Egypt, bringing a curse upon Pharaoh for his hardness of heart, this mighty messenger of the Abyss visits his destruction wherever and whenever he finds, not the absence of the typical blood upon the door, but when he finds it, or any evidence of allegiance to the One whose sacrificial blood he seeks to destroy.
