13:34 A new commandment. There is nothing new about the command to love, since Lev. 19:18 teaches to “love your neighbor as yourself.” The new element is the change from “neighbor” to “one another” and the change from “as yourself” to “as I have loved you.” Christian love has Christ’s sacrificial love as its model, and the community of believers as the primary (though by no means exclusive) place in which it is expressed (cf. Matt. 25:40; Gal. 6:10; Eph. 5:25). See “Love” at 1 Cor. 13:13.
