I received an e-mail from Dr. Peter Kwasniewski informing me that the Aquinas Institute at Wyoming Catholic College will soon publish the first volume of their planned Latin/English omnia opera of St. Thomas Aquinas. They are beginning with the Angelic Doctor's commentaries on St. Paul. The first volume will be Romans. Here is a sample of the first three pages. You'll notice that the commentaries include the Greek text.
You can pre-order before July 16 at a reduced price. You can either order individual volumes or combinations of various texts, or the whole series.
