In book VI. on _The Providence of God,_ Salvian continues his arraignment: "We rush from the churches to the theatres, even in the midst of our perils. In Carthage the theatres were thronged while the enemy were before the walls, and the cries of those perishing outside under the sword mingled with the shouts of the spectators in the circus. Nor are we better here in Gaul. Treves has been taken four times, and has only increased in wickedness under her misfortunes. The same state of things exists in Cologne--deplorable wickedness among young and old, low and high. The smaller cities have been blind and insensible to the dangers threatening, until they have overwhelmed them. It seems to be the destiny of the Roman empire to perish rather than reform; they must cease to be, in order to cease to be vicious. A part of the inhabitants of Treves, having escaped from the ruins, petitions the emperor for--what? A theatre, spectacles, public shows! A city which thrice overthrown could not correct itself, well deserved to suffer a fourth destruction. * * * Would that my voice might be heard by all Romans! I would cry: Let us all blush that today the only cities where impurity does not reign are those which have submitted to the barbarians. Think not, then, that they conquer and we yield by the simple force of nature. Rather let us admit that we succumb through dissoluteness of our morals, of which our calamities are the just punishment." The moral condition of the church did not improve in the sixth nor the seventh century. It kept getting worse and worse until in the tenth century those writers most interested in upholding the purity of the church declare that this was an iron age, barren of all goodness; a leaden age, abounding in all wickedness; and a dark age, remarkable for the scarcity of writers and men of learning. Christ is represented as in a very deep sleep, the ship as covered with waves, and there were no disciples who by their cries might wake him, being themselves asleep. [19] "Infidel Malice," says Milner, "has with pleasure recorded the vices and crimes of the popes of this century. Nor is it my intention to attempt to palliate the account of their wickedness. It was as deep and atrocious as language can paint; nor can a reasonable man desire more authentic evidence of history than that which the records both of civil and ecclesiastical history afford concerning the corruption of the whole church." [20] As already remarked, it is the contention of the Roman Catholic Church that from Peter to Leo XIII. there has been an uninterrupted line of bishops in the see of Rome who have held divine authority; who succeeded both to the divine authority and mission of St. Peter; with power to bind and loose on earth and in heaven; who were, in fact, the vicars of Christ on earth, presidents of the church universal.
