Tried watching the video. Turned it off. So many errors. Joel just can’t seem to grasp that a man can be one flesh with more than one woman, even though scripture clearly teaches that.
I haven't watched it, but your comment made me think of the fact that they always put forward a polyamours union as their example of marriage when arguing against polygyny using creation ideal.
Logically they are saying one man and wive(s) equals one union, but this cannot be true because the maximum amount of people (using The Most High's intential design) that can create another person is two. This is a hard limit, a lineage can only decend from a two person union. Copulating with additional people will not change that fact, only create additional people of a seperate lineage (if done in the right order M+W). The descendant cannot be split between 3 or more people, nor is there a new or additional lineage branch formed from 3 or more coming together. Similiarly neither can the two wives acting indepently of the the husband in his stead (W+W) add to the lineage of either wife or a polyamory based union of all three.
If each additonal wife is grafted into the original union, making a union of 3+ instead of two, then according to their proposed example of creation ideal polygyny would not create additional lineages, all would descend from that single union and it would require all particpants of that union to expand that lineage. Obviously though the wives cannot create additional offspring of Abraham. Neither can they for eachother.
Exposing the fallacy of this logic by presenting an example which indisputably shows that the coming together of two can only make a third person descended from that specific union, demonstrates exactly that. The inclusion of another person doesn't change this. This throws a wrench in the polyamory marriage example argument, the Adam, Eve, and a third argument cannot stand in the face of this.
For example, Abraham, Sarah, and Hagar did not consumate Ishmael through a polyamorus orgy as a requirement where they then shared the pregnancy. Ishmael is not of the line of Hagar AND Sarah AND Abraham. Only Abraham and Hagar as a single union, seperate from Abraham and Sarah's union. Likewise the inverse for Isaac is true, only Abraham and Sarah can create Isaacs lineage. Neither lineage can be parsed out or redistributed amongst the polyamorously proposed union.
The argument presented of polyamory as not the creation ideal is correct, but it is also not applicable because of this.
