Rigorism and Moral Laxity in Early Christian Heritical Movements Based on "Diversarum hereseon liber" of Philastrius of Brescia

Abstract

The objective of the article is to illustrate the two extremes represented by the broad assortment of movements: the ascetic rigorism and moral laxity. The primary source of text is the first Latin catalogue of heresies, written between 380 and 388 by the Bishop of Brescia, Philastrius. The source selection was dictated on twofold grounds. The treaty contains the most numerous descriptions of heretical groups, yet at the same time is the least known of its kind. The information enclosed in Philastrius’ work, summarized in a comparative manner with the descriptions found in other patristic catalogues of heresy – by Epiphanius, Theodoret of Cyrus, John Damascene, Augustine and Isidore of Seville – lead to the following conclusions: 1) for the most part heretical movements followed the ascetic radicalism, motivated most habitually by an exaggerated literal exegesis of the biblical texts (eg. Gnostics, Encratites, Discalced); 2) the few of the laxative-approach movements operated on moral promiscuity (eg. Simonians, Carpocratians, Symmachians), the extent of which is difficult to assess due to the raised issues with the objectivity of Philastrius’ work – undermined by the use of invectives and the apologetic attitude of the author employed in order to defend the orthodox doctrine and morals; 3) paradoxically, there existed also groups that combined inconsistently promiscuity with the elements of asceticism (eg. Borborites, Adamites).
