Manichæanism in Rome.
This epistle, addressed to the bishops throughout Italy, shows the way in which zealous bishops could, and were expected to, co-operate with the secular authorities in putting down heresy.
Leo the Great [440-461], the greatest of the popes before Gregory the Great, was equally great as an ecclesiastical statesman, as theologian, and universally acknowledged leader of the Roman people in the times of the invasions of Attila and Genseric. Without being the creator of the papal idea, he was able so to gather up the elements that had been developed by Siricius, Innocent, and others, as to give it a classical expression that almost warrants one in describing him as the first of the popes in the later sense of that term. His literary remains consist of sermons, of which ninety-six are genuine, in which, among other matters, he sets forth his conception of the Petrine prerogative (see below, [§ 87, b]), and letters in which he deals with the largest questions of ecclesiastical politics, especially in the matter of the condemnation of Monophysitism at the Council of Chalcedon. See below, [§ 91].
Our search has discovered in the city a great many followers and teachers of the Manichæan impiety, our watchfulness has proclaimed them, and our authority and censure have [pg 377] checked them: those whom we could reform we have corrected and driven to condemn Manichæus with his preachings and teachings, by public confession in the Church, and by the subscription of their own hands; and thus we have lifted those who have acknowledged their fault from the pit of their impiety, by granting them opportunity for repentance. But some who had so deeply involved themselves that no remedy could assist them have been subjected to the laws, in accordance with the constitutions of our Christian princes, and lest they should pollute the holy flock by their contagion, have been banished into perpetual exile by the public judges. And all the profane and disgraceful things which are found, as well in their writings as in their secret traditions, we have disclosed and clearly proved to the eyes of Christian laity, that the people might know what to shrink from or avoid; so that he that was called their bishop was himself tried by us and betrayed the criminal views which he held in his mystic religion, as the record of our proceedings can show you. For this, too, we have sent you for instruction; and after reading them you will be able to understand all the discoveries we have made.
And because we know that some of those who are involved here in too close an accusation for them to clear themselves have fled, we have sent this letter to you, beloved, by our acolyte; that your holiness, dear brothers, may be informed of this, and see fit to act more diligently and cautiously, lest the men of Manichæan error be able to find opportunity of hurting your people and of teaching these impious doctrines. For we cannot otherwise rule those intrusted to us unless we pursue, with the zeal of faith in the Lord, those who are destroyers and destroyed; and with what severity we can bring to bear, cut them off from intercourse with sound minds, lest this pestilence spread much wider. Wherefore I exhort you, beloved, I beseech and warn you to use such watchful diligence as you ought and can employ in tracking them out lest they find opportunity of concealment anywhere.
(g) Leo the Great, Epistula 15. (MSL, 54:680.)
An account of the tenets of the Priscillianists. Leo is answering a letter sent him by Bishop Turribius of Asturia, in which that bishop had given him statements about the faith of these sectaries. It appears that these statements which Leo quotes and refutes in brief are not wholly correct and that the Priscillianists were far from being as heretical as they have been commonly represented. See articles in the recent encyclopædias, e.g., New Schaff-Herzog, and Encyclopædia Britannica, 11th ed. The change in opinion is due to the discovery of writings of Priscillian himself. Nevertheless, these statements, defective as they may be, represent the opinion of the times as to these heretics and the general attitude toward what was regarded as heretical and savoring of Manichæanism.[136]
1. And so under the first head is shown what impious views they hold about the divine Trinity; they affirm that the person of the Father, the Son, and the Holy Ghost is one and the same, as if the same God were named now Father, now Son, now Holy Ghost; and as if He who begat were not one, He who was begotten another, and He who proceedeth from both yet another; but an undivided unity must be understood, spoken of under three names, but not consisting of three persons.…
2. Under the second head is displayed their foolish and empty fancy about the issue of certain virtues from God which He began to possess, and which were posterior to God in His own essence.…
3. Again the language of the third head shows that these same impious persons assert that the Son of God is called “only begotten” for this reason that He alone was born of a virgin.…
