Although Christians believe that God has a wife (Mary) Biblical scholars agree that he also had one in the OT. It comes partly from reading the Bible and encountering passages referring to other gods, actually the pantheon of Gods to which OT God frequently talks to and also from archeological evidence where they can see that ancient Jews were polytheist and also worshiped statues of Goddess that was OT God's wife.
teachings of the Bible are so muddled and self-contradictory that it was possible for Christians to happily burn heretics alive for five long centuries. It was even possible for the most venerated patriarchs of the Church, like St. Augustine and St. Thomas Aquinas, to conclude that heretics should be tortured (Augustine) or killed outright (Aquinas). Martin Luther and John Calvin advocated the wholesale murder of heretics, apostates, Jews, and witches. - Sam Harris, "Letter To A Christian Nation"
