Real quick, try to keep it simple:

Jesus is the Zodiac fulfilled in flesh; As Above, so below

One amazing birthchart with all the proper correspondences and alignments in the heavens at the meridian of time in our age.

People knew of this celestial play since Adamic times and anticipated the messiah who would restore fallen humanity.

Between, then, Adamic society and 0 A.D., many "almost" messiahs came, spoke, went and left behind cults. Why?

Gonna say it slow:

Zodiac...is...cyclical.... So every so often you would have a birth chart that was amazingly close to Christ, producing all sorts of quasi-Messiahs.

Mystery School Adepts would guide these almost Messiahs to live the life that was deduced from Astrological study.
