Opus Imperfectum


Opus Imperfectum in Matthaeum is an early Christian commentary on the Gospel of Matthew, written sometime in the 5th century. Its name is derived from the fact that it is incomplete, omitting a number of passages from Matthew.
Its authorship was for centuries wrongly attributed to John Chrysostom, a misconception first refuted by Erasmus in 1530. Some candidates for its authorship include an Arian priest in Constantinople named Timothy; Maximinus, an Arian bishop who accompanied the Goths; and Anianus of Celeda.
It exhibits a mildly Arian Christology, and represents the sometimes confused theology that permeated Christianity in its formative centuries. It was well regarded into the Middle Ages in spite of its theological deficiencies, but fell out of widespread study after Erasmus' critique.
Thomas Aquinas was said to have remarked that he would rather have the completed work than to be mayor of Paris.
Gustavo Piemonte has attributed two group of homilies to a lost work of Johannes Scotus Eriugena, the Tractatus in Matheum.
