I came to a conclusion that I thought was interesting when discussing my thoughts on The Trinity.
From Conventional Jewish Thought, El (God) is One as in one entity, what Christians typically call "The Father".
But then I realized El is one, as in one unit a family in the reflection of The Almighty's perfect design, The Father ("God" /Elohim / Yah ) is the father who corrects, The Mother (The Holy Spirit / Ruach Ha-Kodesh) is the mother who nutures, and The Son (Jesus/Yeshua) is the son who leaves his parents to join his wife, The Church.
When a man leaves his parents household, he becomes one with his wife, in Judaism this concept is called Echad, which transcends the physical manifestation of a child's birth, a child is simply a reflection of the unity of bond between a husband, & wife, it is a deep connection.
