When the barbarians were finally established and converted, and some ties formed between them and the church, it did not cease to incur great danger from them. The brutality and recklessness in the barbarian manners were such, that the new creed, and the sentiments with which it had inspired them, exercised very little sway over them. Violence soon reassumed the upper hand, and the church was a victim to it equally with the rest of society. As a means of defence, it proclaimed a principle formerly asserted, although more indefinitely, under the Empire--namely, the separation of spiritual from temporal power, and their reciprocal independence. By the aid of this principle it was that the church continued unmolested by the barbarians. The church maintained that force could have no action upon a system of religious articles, hopes, and promises, and therefore that the temporal world was completely severed from the spiritual. {101} The salutary consequences resulting from this principle are discernible at a glance. Independently of the temporary utility it was to the church, it had the inestimable advantage of placing on the basis of right the separation of the two powers, and of controlling them by means of each other. Furthermore, by sustaining the independence of the intellectual world in general, in its full extent, the church prepared the way for the independence of individual intellect and of thought. The church said that the system of religious belief could not fall under the yoke of force, so each individual was tempted to use the same language on his own account. The principle of free discussion or examination, and of liberty for individual thought, is exactly the same as that of the independence of the general spiritual authority with respect to the temporal power. Unfortunately, it is an easy matter to pass from the want of liberty to the lust of dominion. The church exhibited a proof of it at this period. By a tendency natural to human ambition and pride, the church endeavoured to establish for the spiritual power not only independence, but supremacy over the temporal power. Yet we must not believe that this pretension had no other source than the failings of humanity; there were others still deeper, which it behoves us to inquire into.
