"Gibbon was not interested in religious doctrine, though he amused himself with its speculative refinements. But religion and Churches, he would admit, are a social and psychological necessity, and the particular forms which they take are important, for they can influence the progress or decline of civilization. Therefore the historical question he asked was, did the ideas of Christianity and the organization of the Church, as adapted to the Roman Empire, generate or stifle public spirit, freedom, and the advancement of knowledge and a plural society. His answer was that they stifled it. If Christianity had first been established in independent city-states like those of Greece, perhaps it would have assumed a different and more useful form – as it eventually did in the communes of Italy and, more successfully, in the Protestant cities of Switzerland. But the very fact of its establishment by imperial power, as an ideological support to that power, made it subservient to a centralized, monopolist system whose organization and absolutism, in its own formative period, it imitated and sustained."
