Patristics

“For our religion commands us to love even our enemies, and to pray for those who persecute us, aiming at a perfection all its own, and seeking in its disciples something of a higher type than the commonplace goodness of the world. For all of those who love them; it is peculiar to Christians alone to love those who hate them.” Tertullian, To Scapula, 1, ANF 3:105
