Terms for the Divine
Shekhinah means “Presence” or “The Presence” of God. She is the feminine manifestation of God with the people of Israel; she is the Spirit of God. Shekhinah was the Presence in the burning bush, the pillar of cloud/fire that led Israel out of Egypt, the Presence that met Moses on the mountain to give the commandments, and the Presence that dwelt in the Holy of Holies. Shekinah has a direct lineage to the Christian concept of Holy Spirit, the third person of the Triune God. Shekinah is the name Yeshua used when he says Holy Spirit in our translations. Shekhinah, the Holy Spirit, is called Yeshua’s Mother in the Gospel of the Hebrews. I will use "Shekinah" as the name of the Holy Spirit. In the ancient, extrabiblical Jewish writings of the Targumim, Talmud and Midrash, the term "Shekinah" is often used instead of "God". However, in other places the term "Shekinah" is used to describe only an intermediary or manifestation of God. But apart from prior ideas, ultimately it should be clear that God and God’s Spirit are one in the same. So we should just be talking about the One God Yahweh-Shekhinah, which would mean “I Am-Presence” or “I Am-The Presence.”!
Then proceeding on to the Christian concept of Trinity, things can really get confusing, but we are still talking about the One God. Having established the Holy Spirit is feminine, I think the concept of Trinity as Father-Mother-Child makes more sense than the traditional western Church's sexist Father-Son-Holy Spirit. (A son from just a father?!)
