Capricorn.

I was somewhat surprised when an astrologer said to me that Jesus is governed by the sign of Pisces but the Church is governed by Capricorn.

This is because the Church and the State are part of the social authority structure - the establishment.

This is how it was before the fall of Christendom.
The Church was an authority.

When we think now of spirituality we no longer think of an institution invested with social authority.  We think of green trees and political ideals.
God is no longer confined to stone buildings.
He roams freely through nature and acts for social justice.

So perhaps now Christianity can return to the sign of Pisces - the sign of the spirit - and follow Jesus - the teacher of love and forgiveness.
