The Wikipedia article on 'Heavenly Mother' notes that:
Brigham Young taught that God the Father was polygamous, although teachings on Heavenly Mothers were never as popular and disappeared from official rhetoric after the end of LDS polygamy in 1904 (although existing polygynous marriages lasted into the 1950s). Top leaders used the examples of the polygamy of God the Father in defense of the practice and this teaching was widely accepted by the late-1850s. Apostle Orson Pratt taught in an official church periodical that "We have now clearly shown that God the Father had a plurality of wives," and that after her death, Mary (the mother of Jesus) may have become another eternal polygamous wife of God. One scholar interpreted a 1976 LDS manual as alluding to this teaching. Author Carol Lynn Pearson stated that a seminary teacher from her youth fervently taught that there were multiple Heavenly Mothers.
My understanding is that the modern Church of Jesus Christ of Latter-day saints unambiguously bans plural marriage in this lifetime, but allows one person to be sealed to multiple people in the celestial realm (eg, a widower who remarries after his wife's death and has two wives in heaven). Given this, what is the modern teaching of the Church with regards to the idea that members of the Godhead have multiple wives? More specifically, if this teaching has not been repudiated, are all the wives collectively 'Heavenly Mothers', or is one particular wife have a special position as the Heavenly Mother?
(I apologize for using the now disapproved abbreviation 'LDS' in the title—unfortunately, the full name of the Church wouldn't fit well into a short title)
