Owe no man anything, but to love one another: for he that loves another has fulfilled the law.
All Commentaries on Romans 13:8 Go To Romans 13
Augustine of Hippo
AD 430
The only way of cleaving to that pattern is by love. If we love another whom we believe to be righteous, we cannot but love the pattern itself, which shows us what the righteous soul is, in order that we too may become righteous. Indeed, if we did not love the image of God in him, we would have no love for the person, since our love for him is based on the pattern. Yet so long as we ourselves are not righteous, our love of the pattern is not enough to make us righteous.
