"Our Savior is our true Mother in whom we are endlessly born and out of whom we shall never come."
- Julian of Norwich
Usually He/Him are God's pronouns, but God does also have all the aspects or qualities of a mother as well as a father.
Can it be helpful to think of God as feminine?
Do you?
Both male and female came out of God who were made in God's image and likeness.
Jesus came and revealed God as a male, the nuance of "where Eve's unique appearance and behavioral likeness came from" is in the scriptures and seems to relate to the inner workings of God.
Originally, before there was male and female, the first human had all of humanity within him, and this person was called Adam. However, then Adam became as we are today being male and female, and male recognized the female as part of him and they were one though technically separate, this is a profound mystery. The female was not given a name until the exit from the garden, because there was no reason for another name.
In one passage in the proverbs it is said God took Wisdom out of himself before doing His works of old. Wisdom in that body of literature in the scriptures is identified as feminine. The way in which this taking out is described is similar to the rib being taken out of Adam, but since it is a mystery - there are varied opinions on what this means. I take this to mean the Father took Wisdom out of himself and spoke forth the words that created everything, those words became flesh and we know that person as Jesus Christ.
Since the feminine aspect of humanity as well as the masculine aspect of humanity both proceeded from God, looking at humanity from a balanced perspective as far as being in God's image is very helpful.
However, since Christianity isn't about building up energy through libido as is the practice in some of the other religions, the significance of acknowledging God as the source of femininity has a different role in terms of the unique non-mathematical oneness expressed in the teachings.
Also it is important to note that the ancient traditions also have the mother of God theology in regards to Mary who gave birth to his humanity. Though this theology is not my area of expertise, you might find exploring this line of study beneficial as well.
In conclusion, I think it is helpful to know where male and female came from within God, but I think that seeing that both male and female came from within God means that there's more to being human than we thought, and God being the origin is the best teacher.
