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
John Chrysostom
AD 407
Love is a debt which you owe to your brother because of your spiritual relationship to him…. If love departs from us, the whole body is torn in pieces. Therefore love your brother, for if you can fulfill the law by befriending him, then the benefit you receive puts you in his debt.
