     • God’s power; and
     • Evil.

2. Philosophical commentaries
   • Eleven commentaries on Aristotle;
   • Two expositions of works by Boethius;

   • Ninety-nine Homilies Upon the Epistles and Gospels for Forty-nine Sundays of the Year
   • A collection of glosses from the Church Fathers on the Gospels (Catena aurea)
4. Systematic works (Summa Theologiae, Summa contra Gentiles, and commentary on Peter Lombard's Sentences)
5. Biblical commentaries on Job, Psalms and Isaiah, Canticles and Jeremiah, John, Matthew, and on the epistles of Paul
   • Nine exegeses of Scriptural books
6. Liturgical works

Editions

In 1570 the first edition of Aquinas's opera omnia, the so-called editio Piana (from Pius V, the Dominican pope who commissioned it), was produced at the studium of the Roman convent at Santa Maria sopra Minerva, the forerunner of the Pontifical University of Saint Thomas Aquinas, Angelicum.^[1] The critical edition of Aquinas's works is the ongoing edition commissioned by Pope Leo XIII (1882-1903), the so-called Leonine Edition. Abbé Migne published an edition of the Summa Theologiae, in four volumes, as an appendix to his Patrologiae Cursus Completus. English editions: Joseph Rickaby (London, 1872), J. M. Ashley (London, 1888).
