The last word to the slave is a warning against neglect of duty. There is to be a double recompense--to the slave of Christ the portion of a son; to the wrong doer retribution "for the wrong that he has done." Then, though slavery was itself a wrong, though the master who held a man in bondage was himself inflicting the greatest of all wrongs, yet Paul will have the slave think that he still has duties to his master. That is part of Paul's general position as to slavery. He will not wage war against it, but for the present accept it. Whether he saw the full bearing of the gospel on that and other infamous institutions may be questioned. He has given us the principles which will destroy them, but he is no revolutionist, and so his present counsel is to remember the master's rights, even though they be founded on wrong, and he has no hesitation in condemning and predicting retribution for evil things done by a slave to his master. A superior's injustice does not warrant an inferior's breach of moral law, though it may excuse it. Two blacks do not make a white. Herein lies the condemnation of all the crimes which enslaved nations and classes have done, of many a deed which has been honoured and sung, of the sanguinary cruelties of servile revolts, as well as of the questionable means to which labour often resorts in modern industrial warfare. The homely, plain principle, that a man does not receive the right to break God's laws because he is ill-treated, would clear away much fog from some people's notions of how to advance the cause of the oppressed. But, on the other hand, this warning may look towards the masters also; and probably the same double reference is also to be discerned in the closing words to the slaves, "and there is no respect of persons." The servants were naturally tempted to think that God was on their side, as indeed He was, but also to think that the great coming day of judgment was mostly meant to be terrible to tyrants and oppressors, and so to look forward to it with a fierce un-Christian joy, as well as with a false confidence built only on their present misery. They would be apt to think that God did "respect persons," in the opposite fashion from that of a partial judge--namely, that He would incline the scale in favour of the ill-used, the poor, the down-trodden; that they would have an easy test and a light sentence, while His frowns and His severity would be kept for the powerful and the rich who had ground the faces of the poor and kept back the hire of the labourer. It was therefore a needful reminder for them, and for us all, that that judgment has nothing to do with earthly conditions, but only with conduct and character; that sorrow and calamity here do not open heaven's gates hereafter, and that the slave and master are tried by the same law.
