In Matthew 19 Jesus says, ‘For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one". So I searched "and the two shall become one" on catholic.con and couldn't find what I was looking for.
So, my question is since the man and woman become one, what happens when the spouse dies? Would the surviving person become a half a person? I know that sounds funny, but it as caused me to become a bit confused.
