God without Sex
The biblical texts portray God as Father because God is the creative source of all life. In the era in which the biblical texts were composed, the male was believed to be the active, creative contributor to human (and animal) reproduction; the female was understood to be passive, contributing the substance from which the creative force shaped offspring. So while biblical authors may well have conceived of God as male, they did so not on the basis of revelation, but due to their misunderstanding of the reproductive process. Pinning theology to this misunderstanding of biology is as pointless as pinning our understanding of the universe to a mistaken cosmology.
