Revelation is an odd book even to believing christians. Nowhere in the book is Jesus earthly life discussed. Not the sacraments, miracles, his earthly existance, his birth.......nothing.
This book is an obvious hatred for the Roman dictators written by a disgruntled Jew/Jews that wrote in a fantasy world concerning Roman destruction by the hand of a fictitious Jewish messiah who never showed.
The Christ of Revelation is actually born in heaven, and under pretty extraordinary circumstances (his mother is ‘clothed in the sun, with the moon at her feet, wearing twelve stars as a crown’ – a reasonable description of Isis).
"And she brought forth a man child, who was to rule all nations with a rod of iron: and her child was caught up unto God, and to his throne."(Revelation 12.5)
Thus, unlike the later books of the New Testament, Revelation has a Christ born in Heaven who rules on earth – rather than a Christ born on earth who rules in Heaven! There is no human biography at all for this Christ – he is an entirely heavenly figure,Heavenly Warlord.
Nothing in Revelation suggests that this Christ is ever incarnated on earth. Though said to have been ‘dead , and is alive’ (2.8), the circumstances of this dying and rising are never given.
