It occurred to me recently that it is significant that the invisible enemy of our souls is called “the Evil One” in both the Lord’s Prayer and in such passages as 1 John 5:19. That is, our adversary is never named, but only referred to obliquely. He is also referred to as “the Adversary” from the Hebrew word for adversary “satan” (see e.g. the curse in Psalm 109:6 which reads “Appoint a wicked man over him and let a satan stand at his right hand”). This Hebrew word was transliterated into the Greek as Σατάν/ Satan and used as a title in such passages as 1 Thessalonians 2:18. He is also referred to as “the Slanderer” (Greek δίαβολος/ diabololos), usually rendered in English as “the Devil”. Note: all these words are titles, not names; they are in fact verbal circumlocutions used to avoid mentioning his actual name.
