Sabin-
I have no issue with your post about holding hands with non-family members, but they are going a bit far to say that married couples should hold hands discreetly. First, how would you not hold hands discreetly? Maybe you would hold them high up in the air like you just crossed a finish line or won a medal?
They are also taking it a bit far to say that embracing during a prayer is wrong. Why shouldn't I be close to my spouse during a prayer to my Father? He's the creator of marriage right?
