THE DIVINE SHEKINAH: In this stained glass window, the Holy Spirit in the form of a dove is directly connected to the pentagram/pentagon. The planet Venus creates a five pointed star in the heavens once every eight years. The Venus Rose. Christianity only makes sense if we include the Divine Feminine as part of the Holy Trinity. Father God, Mother Goddess, Sacred Child. 

This trinity can be expressed in multiple ways depending on the culture under discussion. Egypt: Osiris as Orion, Isis as Sirius, Horus as Venus. Christianity: God as the Sun, Holy Spirit as Venus, Jesus as Mercury the Divine Messenger. 

It is all about context.
