9 These details from the life of this great saint indicate clearly enough to all good people the way which they must follow. We know that your nation is particularly famous for the wise and fruitful way in which you dedicate your talent and activity to promoting the greatness of your country and ensuring both public and individual prosperity. But, above all, the wise and virtuous among you should make vigorous efforts for the faith, and they should dedicate all their insight and expressive energy to its glory and defense. For the same purpose they should understand and utilize at once every advance made in the arts and sciences.
