Astrology & Christianity

The four most prominent stars in the night sky, and ancient Egypt's four most venerated stars are: the three stars of Orion's Belt and Sirius, the brightest star in the sky.

For the Egyptians, Orion was Osiris, and Sirius was Isis, his wife, sister, and virgin mother of their divine son Horus.

On the winter solstice, the sunrise has reached its southerly most position on the horizon, at which point its movement on the horizon changes direction and starts its journey back towards the north.

The Egyptians celebrated this day as 'the birth of the sun', being the start of the new solar year. It is marked visually when the three stars of Orion's Belt align with Sirius and the winter solstice sunrise position on the horizon; which was, if we lay our calendar over theirs, on the 25th  of December!

This visual astrological event can still be viewed today on the winter solstice at the moment the four stars align, just after Sirius has broken the skyline.

At that point in time, all four stars will be pointing to the position on the horizon where the sun will rise that morning.

Over countless centuries this astrological concept has been plagiarised, morphed and woven into many religions; the latest of  these being Roman Catholic Christianity circa 325 CE (325 AD).

Osiris, Isis and their divine son Horus 'the winter solstice sunrise' has become: "The three kings, the star of the east, and the birth of the son of God".

Were the early Christian Emperors, who followed Constantine, aware of these astrological ties; and if so, did it concern them? 

Emperor Theodosius II who reigned between 408 and 450 CE 

Edict 313: “All astrologers are to be expelled and exiled, unless they burn their books in the presence of a Bishop and convert to Christianity.” 

I wonder?
