The Doctrinal Interests of Marius Mercator

Extract

From the middle of the seventeenth until the end of the first quarter of the twentieth century Marius Mercator was regarded by theologians and historians as one of the most valuable extant sources of information concerning both the Pelagian and Nestorian controversies. The basis of the notable reputation which he so long enjoyed was of course the erroneous belief that he was the compiler of the Palatine Collection, a vast and impressive mass of papal and episcopal letters, remonstrances, sermons, confessions of faith, and memoirs used in the two ecumenical councils of the fifth century. This material concerned, almost exclusively, the heresies of Pelagius and Nestorius and apparently had been gathered together for use against the adherents of those two heresiarchs. Though little could be learned about Mercator himself, the available information gave him an impeccable position in the ranks of the orthodox. He was a disciple and correspondent of Augustine, whom he supported by savage attacks on Pelagius and other leaders of the Western heresy, and he was also known to Jerome, who, in a letter sent from distant Palestine to the Roman Donatus in the year 419, included a message to Mercator, encouraging him in his opposition to the Pelagians.

1 For the old opinion of Mereator as the diligent and formidable opponent of both heresies see II. de Noris, Historia Pelagiana, F. Loofs, Nestoriana, Tillemont, Bardenhewer, and the references in theological studies and ecclesiastical histories of the period. The general opinion was recognized by the devotion of the whole of the forty-eighth volume of Migne's Patrologia latina to Mercator's works, in the edition of Father Jean Garnier with the addition of some of the notes and opinions of Etienne Baluze.

4 An example of Schwartz's method of arriving at his conclusion will be revealing. It seems likely that certain Nestorian writings included by Mereator (ACO, I, 5, 55–50Google Scholar) were part of a group of excerpts from Nestorius made in Alexandria at the order of Cyril and sent by him to the pope (Ep. to Celestine, Mansi, IV, 10161017Google Scholar. Since Schwartz had decided that Mereator obtained these works from Cyril, he concluded that Cyril must have sent copies to his agents in Constantinople, who handed them on to Mercator. It may have happened in that way, but at the same time there is nothing against the possibility that Mereator got the excerpts directly from the pope. Schwartz was so firm in his belief that Mercator was living in Thrace, from where he kept in touch with Cyril's representatives in Constantinople, that he overlooked the simpler and easier explanation. For Schwartz's theories and conclusions, see ACO, I, 5Google Scholar, XII–XIV and “Die sogenannten Gegenanathematismen des Nestorius” in Sitzimgsb. d. Bay. Agad. zu München, hist.-phil. Klasse (1922).Google Scholar

5 If it is true that Mercator, after becoming a monk, wrote only for the use of monks, it was a striking change, for of his two commonitoria, one had been presented even to Theodosius and the other was an attempt to add to Augustine's work. See ACO, I, 5, 65Google Scholar and ACO, I, 5, 7Google Scholar. Mercator does not say in so many words that he is attempting to finish the work of his illustrious master but he makes it clear, nevertheless, that such is his ambition. What were those works, supposedly written by Mereator as a monk? No original treatises but only a few translations! Schwartz believed they indicated that Mercator had become inflamed against Nestorius and Theodore of Mopsuestia, It seems strange that Mercator's hatred and contempt for the Eastern heresy could have stirred him to attack only after Nestorianism had been condemned, as must have been the case if Schwartz is correct, and that such feelings could have provoked him only to translation.

6 Duchesne, Louis, Histoire ancienne de l'église (Paris, 1911), III, 408409Google Scholar, wrote of Mercator as one of the most intransigeant of Cyrulians, but at the time when Duchesne wrote the whole Collectio Palatina was still attributed to Mereator. It was to Rome, it seems to me, that Mercator looked for guidance, rather than Alexandria. Duchesne also considered this more acceptable view that Mereator was a papal agent, op. cit., 331. The same suggestion was put forward by Casper, Erich, Geschichte des Papsttums von den Anf ngen bis zur Höhe der Weltherrschaft (Tübingen, 1930), I, 392.Google Scholar

9 Eltester in his article, ‘Marins Mercator’, in Pauly- Wissowa (1930), XIV, 1932, who follows Schwartz at almost every point, naturally does not recognize Mercator's primary concern with Pelagianism. He believes that by mingling works against the Pelagians with others against the Nestorians Mercator meant to calumniate both heresies. But neither Schwartz nor Eltester explains why Mercator does not take up the Christological controversy in any of his own writings, but merely calls it ‘impious,’ etc. See below.

15 That one work is the comparison of the doctrines of Nestorius and Paul of Bamosata, written apparently for the purpose of vilifying Nestorius by connecting him with Paul and revealing no remarkable knowledge of Nestorianism. For it see ACO, I, 5, 28Google Scholar. In the following works of Nestorius and Cyril, pp. 28–60, there is no attempt at interpretation whatsoever.

Celestine ordered his legates to give their support to Cyril not because the pope condemned Nestorius's theology but because he disapproved of Nestorius's refusal to break with the Western heretics. No effects on Nestorius's part to accommodate the pope in the Christologieal matter could assuage the papal wrath.

19 Cyril had actually received the Pelagians into communion in the East, before he knew or cared what they believed. It was only later that they came to have any significance for him.

20 That is, Mercator wished to point out that the Western heretics found a warm welcome only with other heretics, viz. Nestorius and Theodore. The Pelagians were belittled for associating with Nestorius and the Nestorians for receiving the Pelagians. Then as a further insult Mereator adds the deceptive, misnamed anti-Pelagian tractates of Nestorius in order to make it look as if the Pelagians were thus attacked by their last friend.
