Within the Latter Day Saint movement, there are a number of theologies regarding the nature of God. In the Fellowship, and within Mormon Kabbalah, we accept all of them. It’s about how God reveals Himself, or Themselves, to us as individuals. We build, as it were, our own religions.
Our Mother in Heaven is someone to identify with, to know. And there is more evidence to be found in scriptures canonized by the original Church of Christ though ignored by the majority of Latter Day Saints today, the Apocrypha.
