CHAPTER XLIX: Conquest Of Italy By The Franks .-- Part II.
Two original epistles, from Gregory the Second to the emperor Leo, are still extant; and if they cannot be praised as the most perfect models of eloquence and logic, they exhibit the portrait, or at least the mask, of the founder of the papal monarchy.

"During ten pure and fortunate years," says Gregory to the emperor, "we have tasted the annual comfort of your royal letters, subscribed in purple ink, with your own hand, the sacred pledges of your attachment to the orthodox creed of our fathers.
How deplorable is the change! how tremendous the scandal! You now accuse the Catholics of idolatry; and, by the accusation, you betray your own impiety and ignorance.

To this ignorance we are compelled to adapt the grossness of our style and arguments: the first elements of holy letters are sufficient for your confusion; and were you to enter a grammar-school, and avow yourself the enemy of our worship, the simple and pious children would be provoked to cast their horn-books at your head." After this decent salutation, the pope attempts the usual distinction between the idols of antiquity and the Christian images.
The former were the fanciful representations of phantoms or daemons, at a time when the true God had not manifested his person in any visible likeness.

The latter are the genuine forms of Christ, his mother, and his saints, who had approved, by a crowd of miracles, the innocence and merit of this relative worship.

He must indeed have trusted to the ignorance of Leo, since he could assert the perpetual use of images, from the apostolic age, and their venerable presence in the six synods of the Catholic church.
