anti-christ, using accurate bible greek meaning of the word, actually means a "christ likeness", or a "pretender christ", an archetype. Means "in the place of..." "instead of", "for" "in exchange". Remember, Christ warned the disciples of those who would "come in his name" meaning pretenders to the throne. "Vicar of Christ" sure fits that description.
