" One of the greatest obstacles to such a synthesis is sectarianism, which is always right and displays no tolerance, picking and fomenting quarrels for the holiest of reasons in order to set itself up in the place of religion and brand anyone who thinks differently as a lost sheep, if nothing worse. But have any human beings the right to totalitarian claims? This claim, certainly, is so morally dangerous that we would do better to leave its fulfilment to Almighty God rather than presume to be little gods ourselves at the expense of our fellow-men. "
