who did not sin, "neither was deceit found in his mouth."

 (i) Christianity introduced a new relationship between master and man. When Paul sent the runaway slave Onesimus back to Philemon, he did not for a moment suggest that Philemon should set Onesimus free. He did not suggest that Philemon should cease to be the master and that Onesimus should cease to be the slave. What he did say was that Philemon must receive Onesimus not now as a servant, but as a brother beloved ( Philemon 1:16). Christianity did not abolish social differences; but it introduced a new relationship of brotherhood in which these other differences were overpassed and transformed. Where there is real brotherhood, it does not matter if you call one man master and the other servant. There is between them a bond which transforms the necessary differences which the circumstances of life make necessary. The solution of the world's problems lies in the new relationship between man and man.
