“In the Catholic colonies, however, of New France and New Spain, if the half-breed were a good Catholic he was regarded as a Frenchman or a Spaniard, as the case might be. This fact alone gives the clew to many of our Colonial wars where the Indians, other than the Iroquois, were persuaded to join the French against the Americans by half-breeds who considered themselves French-men. The Church of Rome has everywhere used its influence to break down racial distinctions. It disregards origins and only requires obedience to the mandates of the universal church. In that lies the secret of the opposition of Rome to all national movements. It maintains the imperial as contrasted with the nationalistic ideal and in that respect its inheritance is direct from the Empire. Race consciousness in the Colonies and in the United States, down to and including the Mexican War, seems to have been very strongly developed among native Americans and it still remains in full vigor to-day in the South, where the presence of a large Negro population forces this question upon the daily attention of the whites.
In New England, however, whether through the decline of Calvinism or the growth of altruism, there appeared early in the last century a wave of sentimentalism, which at that time took up the cause of the Negro and in so doing apparently destroyed, to a large extent, pride and consciousness of race in the North.”
