Dr. Walter Martin addresses The Mormon Church doctrine of Literal Heavenly Wife. This is a cutout clip from the video: "The Maze of Mormonism, Dr. Walter Martin, 1989".

The Mormon Church believes that God has a Literal Wife.
The Mormon Church has a hymn #292 "O My Father", about Heavenly Mother, quote:

"In the heavens are parents single?
No, the thought makes reason stare.
Truth is reason: truth eternal
tells me I've a mother there.

When I leave this frail existence,
When I lay this mortal by,
Father, Mother, may I meet you
in your royal courts on high?"

The Mormon Church officially published the video of this song performed by Tabernacle Choir on their official General Conference Youtube Channel:    • O My Father
