As a commentary on the Acts of the Apostles, this Work stands alone among the writings of the first ten centuries. The Expositions of St. Clement of Alexandria (in the Hypotyposes), of Origen, of Diodorus of Tarsus, and St. Chrysostom's teacher, Theodore of Mopsuestia, as well as of Ammonius and others whose materials are used in the Catena, have perished. Those who are acquainted with the characteristic qualities of St. Chrysostom's exegesis, will perceive here also the same excellencies which mark his other expository works-especially the clear and full exposition of the historical sense, and the exact appreciation of the rhetorical momenta in the discourses of St. Peter, St. Stephen, St. James and St. Paul, as recorded in the Acts.
