Cyprian of Carthage, Three Books of Testimonies Against the Jews III.50: That even our enemies must be loved

In the Gospel according to Luke: “If ye love those who love you, what thank have ye? For even sinners love those who love them.” Also according to Matthew: “Love your enemies, and pray for those who persecute you, that ye may be the children of your Father who is in heaven, who maketh His sun to rise upon the good and the evil, and giveth rain upon the righteous and the unrighteous.”
