As that, Thou shalt not lust, was not spoken to the flesh, but to the spirit, so in this the flesh indeed is not able to love its enemy, but the spirit is able; for the love and hate of the flesh is in the sense, but of the spirit is in the understanding. If then we feel hate to one who has wronged us, and yet will not to act upon that feeling, know that our flesh hates our enemy, but our soul loves him.
