Druthmar, Christian a monk in the abbey of Corbey in the ninth century, was born in Aquitaiie, and afterwards taught in the monasteries of Stavelo and Malmedy, in the diocese of Liege. He left a commentary on St. Matthew (Strasburg, 1514; Haguenau, 1530, fol.). "It contains some opinions respecting transubstantiation decidedly opposed to those of modern Romanism, though they were regarded as orthodox at the time of his writing. He commenced a commentary on St. Luke and St. John, which he did not live to finish. For St. Mark he refers his pupils to a commentary of Bede." His commentary on St. Luke and St. John was printed at Haguenan in 1530, in the Bibliotheca Patrum (t. 15, page 86). The edition of Haguenau was edited by Johann Secer, a Lutheran, and Wetzer und Welte (Kirchen- Lexikon, 3:321) say that he perverted and garbled the text so as to make it oppose transubstantiation. His text runs: "Hoc est corpus meum, i.e., in sacramento . . . transferens spiritualiter corpus in panem, in vinum sanguinem." On the other hand, Sixtus of Siena asserts that he found a MSS. in the Franciscan monastery at Lyons, in which the words run: Hoc est corpus meum, hoc est, vere in sacramento subsistens . . . transferens panem in corpus et vinum in sanguinem.
