I was just having a little fun stretching things.
I do not discount the possibility that Chritians might be asked to practice polygamy at sometime in the future in response to some catastropic event . . . such as there being too many gelded liberal males and homosexual males (I relize I may be redundant here) and too few available Christian males to provide husbands for willing Christian females. There is even a reference in Isaiah 4:1 as follows:
And in that day seven women shall take hold of one man, saying, We will eat our own bread, and wear our own apparel: only let us be called by thy name, to take away our reproach.
This may be a prophecy that sanctions polygamy under unusual circumstances, but I think it is more likely a prophecy on the unusual circumstances without the sanction.
