(15) If a man say, I love God, and hateth his brother, he is a liar: (16) for he that loveth not his brother whom he hath seen, how can he love God whom he hath not seen?
(15) As he showed that the love of our neighbour cannot be separate from the love with which God loves us because this last gives rise to the other: so he denies that the other kind of love with which we love God, can be separate from the love of our neighbour: of which it follows, that they who say they worship God, and yet do not regard their neighbours lie shamelessly.
(16) The first reason taken from comparison: why we cannot hate our neighbour and love God, that is, because he that cannot love his brother whom he sees, how can he love God whom he cannot see?
