This is to document the recent correction of several errata in the first pressings of Johannes Oecolampadius (1482—1531), Sermons on the First Epistle of John (A Handbook for the Christian Life). In addition to a number of spelling corrections, two dates on p. 5 were off by a factor of ten: JO matriculated in Tübingen in 1513, not 1523, and he left Tübingen in the summer of 1514, not 1524. [Apologies to Jeff Fisher for introducing this error into a quotation taken from his fine work.] Also, on p. 9, I have changed "John Chrysostom" to "the Greek Fathers", and after "the sermons of Chrysostom," inserted the phrase, "begun in Mainz," which is more accurate. The influence of Chrysostom on JO is undoubtedly the most decisive, but as Staehelin's reconstruction makes clear at several points, it is only in Mainz that JO's work on this particular Greek Father begins. Any copies of this translation ordered after November 16, 2018 will reflect these most recent corrections. Anyone with earlier copies may wish to pencil in these corrections.
