MARCO L'EREMITA. – Ascetic and dogmatic writer. Photius (Bibl., cod. 200) knew of M. nine writings, without discussing his person. Nicephorus Callistus mentions him in his Hist. eccl., 14, 30, 53, 54 (PG 146), alongside Nilus and Isidore of Pelusium, as a disciple of s. Chrysostom, a piece of information already found in the Chronicon of George Hamartolos (PG 110, 734 B); M. would therefore have lived in the first half of the 5th century. In any case, he should not be confused with the Marco of the Historia Lausiaca, 20 ff.
The treatise De lege spirituali deals with the spiritual law according to Rom. 7:14. Connected with this work is the little treatise De Poenitentia, which proclaims the necessity of Penance even for the perfect among the monks. The De Baptismo contains a polemic against the errors of the Messalians concerning this Sacrament. Other writings are Praecepta salutaria ad Nicolaum monachum; Disputatio cum quodam considicio; Consultatio intellectus cum sua ipsius anima; De ieiunio; In Melchisedek, a polemic against a heresy that asserted the divinity of Melchisedek, in the sense that he would have been a theophany of the Word not yet incarnate. M. also wrote a polemical work against the Nestorians. At the center of his interest is the struggle against the Messalians (v. H. Dörries, Symeon V. Mesopotamien [Texte und Untersuchungen, 55, 1], Lipsia 1941, pp. 95, 444 ff; E. Klostermann, Symeon und Macarius, Berlino 1943, p. 8, n. 1).
