That it is of much moment to make account of religion; and that Italy, through the Roman Church, being wanting therein, has been ruined.
Princes and commonwealths that would save themselves from growing corrupted, should before all things keep uncorrupted the rites and ceremonies of religion, and always hold them in reverence; since we can have no surer sign of the decay of a province than to see divine worship held therein in contempt. This is easily understood when it is seen on what foundation that religion rests in which a man is born. For every religion has its root in certain fundamental ordinances peculiar to itself.
The religion of the Gentiles had its beginning in the responses of the oracles and in the prognostics of the augurs and soothsayers. All their other ceremonies and observances depended upon these; because men naturally believed that the God who could forecast their future weal or woe, could also bring them to pass. Wherefore the temples, the prayers, the sacrifices, and all the other rites of their worship, had their origin in this, that the oracles of Delos, of Dodona, and others celebrated in antiquity, held the world admiring and devout. But, afterwards, when these oracles began to shape their answers to suit the interests of powerful men, and their impostures to be seen through by the multitude, men grew incredulous and ready to overturn every sacred institution. For which reason, the rulers of kingdoms and commonwealths should maintain the foundations of the faith which they hold; since thus it will be easy for them to keep their country religious, and, consequently, virtuous and united. To which end they should countenance and further whatsoever tells in favour of religion, even should they think it untrue; and the wiser they are, and the better they are acquainted with natural causes, the more ought they to do so.
