SICUT UNIVERSITATIS CONDITOR
LETTER OF INNOCENT III
NOVEMBER 3, 1198
To the noble man Acerbus and to the other leadrers of Tuscany and of the Duchy.
Just as God, founder of the universe, has constituted two large luminaries in the firmament of Heaven, a major one to dominate the day and a minor one to dominate the night, so he has established in the firmament of the Universal Church, which is signified by the name of Heaven, two great dignities, a major one to preside--so to speak--over the days of the souls, and a minor one to preside over the nights of the bodies. They are the Pontifical authority and the royal power. Thus, as the moon receives its light from the sun and for this very reason is minor both in quantity and in quality, in its size and in its effect, so the royal power derives from the Pontifical authority the splendour of its dignity, the more of which is inherent in it, the less is the light with which it is adorned, whereas the more it is distant from its reach, the more it benefits in splendour. Both these powers or leaderships have had their seat established in Italy, which country consequently obtained the precedence over all provinces by Divine disposition. And therefore, as it is lawful that we should extend the watchfulness of our providence to all provinces, we must especially and with paternal solicitude provide for Italy where the foundation of the Christian religion has been set up and where the pre-eminence of the priesthood and kingship stands prominent through the primacy of the Apostolic See.
We therefore admonish and exhort you all in the Lord through this Apostolic letter, enjoining that since you receive a true and firm assurance from us who--as it is fitting for the Apostolic dignity--intend to do more for you than we want to promise, you should always endeavour to act in a way which would add to the honour and growth of the Roman Church so as to deserve and strengthen the pledge of her favour and friendship.
