Christian marriage is, and always has been, a reflection of the Trinity, Christ at the centre, with the man and wife joined as one. In Genesis, it talks about two becoming one but it is assumed that Christ is at the centre.
I’ve never heard of that concept.
And when you think about it, marriage can’t possibly reflect the Triune God. There’s no correlation between the parties to a marriage and the Persons of the Godhead. Indeed the very nature of the Trinity is sublime and Holy, beyond any measure which man, or woman, or man and woman, can ever conceive, let only attain.
By the way, our Jewish Freepers might hesitate to accept the premise that Moses intended as he wrote Genesis that his readers of any era would assume that Jesus was a party in a marriage between a man and a woman.
And why Jesus anyway? Why not the Holy Spirit? That would seem to make more sense if our goal was to somehow crowd one part of the Trinity into the marriage dyad.
