In the important controversy between Sir Thomas More and Christopher St. German during the year 1533 — a controversy whose importance reaches into theological domains and involves also the vexatious conflict between the common law and the Roman canon law in England — we find a citation of St. John Chrysostom used first by St. German and then accepted and repeated by More. The apparent source is Chrysostom's famous commentary on St. Matthew, and this work (translated by Burgundio of Pisa in the later twelfth century) is, as Miss Smalley reminds us, the book “which St. Thomas Aquinas preferred to the whole town of Paris….” Further involved, of course, is the larger problem of the influence of St. John Chrysostom before and during the sixteenth century, as well as the technical question of methods of using commentaries on Scripture and thus the weight of auctoritas among the early Tudor controversialists. While it is only the modest story of one maxim that I wish to call attention to in this brief paper, I think that we shall in addition learn something of the English fortunes of one of the most widely used medieval compendia of commentaries, the Catena Aurea of St. Thomas Aquinas.
