The church in Rome wrote to the Corinthians:
Every sedition and every schism was abominable to you. Ye mourned over the transgressions of your neighbors: ye judged their shortcomings to be your own. (1 Clement 2:6)
All glory and enlargement was given unto you, and that was fulfilled which is written My beloved ate and drank and was enlarged and waxed fat and kicked. Hence come jealousy and envy, strife and sedition, persecution and tumult, war and captivity. So men were stirred up, the mean against the honorable, the ill reputed against the highly reputed, the foolish against the wise, the young against the elder.For this cause righteousness and peace stand aloof, while each man hath forsaken the fear of the Lord and become purblind in the faith of Him, neither walketh in the ordinances of His commandments nor liveth according to that which becometh Christ, but each goeth after the lusts of his evil heart, seeing that they have conceived an unrighteous and ungodly jealousy, through which also death entered into the world.
