"It is correctly asserted that the apostles undertook no social propaganda. Paul held no antislavery meetings, and Peter made no public protest against the organized grafting in the Roman system of tax-farming. Of course they did not. Even the most ardent Christian socialist of our day would have stepped softly if he had been in their place. The right of public agitation was very limited in the Roman Empire. Any attempt to arouse the people against the oppression of the government or the special privileges of the possessing classes, would have been choked off with relentless promptness. If, for instance, any one had been known to sow discontent among the vast and ever threatening slave population, — which was not negro, but white, — he would have had short shrift. Society was tensely alert against any possible slave rising. If a slave killed his master, the law provided that every slave of that household should be killed, even if there was no trace of complicity. Upper-class philosophers might permit themselves very noble and liberal sentiments only because there was no connection between them and the masses, and their sentiments ended in perfumed smoke."
