Q. The New Testament says that Yah'shua (Jesus) is allegorically married to the Church (Messianic Community), which of course is a polygamous relationship. But where (if anywhere) does the NT teach that Yah'shua (Jesus) might have been literally married to a smaller number of people? Obviously He cannot be 'literally' married to millions of people in the sense that one is married on earth so there is no mistake that this is an allegory only. In the OT Yahweh is married to Israel and Judah (two allegorical wives) but even these are made up of many millions of souls. The numbers are so big anyway that nobody would make a direct comparison to a normal polygamous family of, say, only two or three wives. I suppose what I'm asking is whether Yah'shua (Jesus) uses any teachings to support a conventional, earthly polygamous marriage?
Yes, He does. Don't you remember the parable of the Ten Virgins? The Bridegroom was to have married ten virgins but five were not prepared spiritually - their lights went out - so there were only five left. According to a New Covenant relevation these five represent (on one level) the five cardinal virtues of Goodness, Justice & Righteousness, Love, Wisdom and Truth (NC&C 207) which are absolutely essential for a polygamous marriage. The five virgins who were locked out of the Marriage feast were Selfishness, Injustice, Hate, Unreason, and Deceit - the five principles that spell death to polygamy.
That Yah'shua (Jesus) was willing to be associated as the Bridegroom with this parable speaks volumes. For an even more controversial Messianic Psalm that suggests overwhelmingly that Yah'shua (Jesus) had to Himself have been married polygamously in mortality, see the article, Eternal Plural Marriage (this article is not for the faint at heart!).
