The following are unpublished translations, done years ago by Fr. Fabian Larcher, of St. Thomas Aquinas's biblical commentaries on Hebrews, Colossians, 1 Corinthians, 2 Corinthians, and Ephesians. Until a couple of years ago, these unpublished translations - good but left unpublished because they are not critical editions (i.e. with footnotes, using the most critically up-to-date Latin text etc.) - existed only in typescripts kept in a box by Fr. Pierre Conway, OP, of the Dominican House in Washington, D.C. He gave the typescripts to the Aquinas Center on the promise that they would be converted into digital format and worked toward publication.
Hebrews - Section 1 (845kb)
Hebrews - Section 2 (1.06mb)
1 Corinthians (1.82mb)
2 Corinthians (1.36 mb)
