The Book of Causes was judged by Thomas Aquinas to have been abstracted from Proclus' Elements of Theology. This commentary is a distinct philosophical work which provides an extended view of his approach to Neoplatonic thought and functions as a guide to his metaphysics.

In his sixth-century work commonly known as the De hebdomadibus, Boethius (ca. 480-524) poses the question of how created things or substances can be good just as they are - that is, good just by existing - without being the same as the source of all goodness, God, who is understood to be Goodness Itself. In his commentary written in the thirteenth century, St. Thomas Aquinas sets out to explain the problem Boethius is treating as well as to explicate Boethius's solution. In doing so, however, the Angelic Doctor suggests a more developed analysis of goodness, based on his own metaphysical...

Thomas Aquinas possessed excellent knowledge of the commentaries of Origen, John Chrysostom, and Augustine. On the basis of this foundation, he produced his own commentary on the Gospel of John as part of his task as a Master of the Sacred Page. Considered a landmark theological introduction to the Fourth Gospel, these lectures were delivered to Dominican friars when Aquinas was at the height of his theological powers, when he was also composing the Summa theologiae. For numerous reasons, the Summa has received far more attention over the centuries than has his Commentary on the Gospel of...
