Medieval Latin Commentators and the Doctrine of Justification by Faith Alone (Sola Fide)

"...a number of Latin commentators echoed the Pauline language of faith alone (sola fide) when commenting on justification in the book of Romans. Examples include Cassiodorus (ca. 485-583), Lanfranc of Bec (ca. 1003-1089), Bruno of Cologne (1032-1101), and Robert of Melun (ca. 1100-1167). A survey of these medieval commentators suggests that they limited their understanding of justification primarily to the remission of past sins only. Nonetheless, it is significant to note that the Reformers were not the first to use the phrase sola fide in their interpretation of Romans."
