"From the time of Adam and Eve, the relationship between a man and a woman has been unique and ordained by God. Eve was created for Adam and to complete his need for companionship. Our earliest records of history depict unification between a man and a woman and their respect for a higher being. It wasn't until Abraham disobeyed God that other women came into the picture and left generations of unrest for those who chose to take more than one wife."
