sorry dude, you did not pull the “fundamental” verse on marriage - you found another verse - one that only indicates that procreation is a part of being male and female...there is NO mention of marriage in your verse.
Fail.
Is it your learned opinion that Jesus was mistaken when he referred back to the scriptures I posted while discussing the law of divorce ? Is it your view that one can be divorced without being married ? Is it then your view Adam and Eve were not married and their children illegitimate, or do you not believe children conceived out of wedlock are illegitimate ?
