On the other hand, preaching took a place it had never previously held in the mediæval Church. Some distinguished Churchmen did not hesitate to say that it was the most important duty the priest could perform—more important than saying Mass. It was recognised that when the people began to read the Bible and religious books in the vernacular, it became necessary for the priests to be able to instruct their congregations intelligently and sympathetically in sermons. Attempts were made to provide the preachers with material for their sermon-making. The earliest was the _Biblia Pauperum_ (the Bible for the _Pauperes Christi_, or the preaching monks), which collects on one page pictures of Bible histories fitted to explain each other, and adds short comments. Thus, on the twenty-fifth leaf there are three pictures—in the centre the Crucifixion; on the left Abraham about to slay Isaac, with the lamb in the foreground; and on the left the Brazen Serpent and the healing of the Plague. More scholarly preachers found a valuable commentary in the _Postilla_ of the learned Franciscan Nicolas de Lyra (Lira or Lire, a village in Normandy), who was the first real exegetical scholar, and to whom Luther was in later days greatly indebted.(69) Manuals of Pastoral Theology were also written and published for the benefit of the parish priests,—the most famous, under the quaint title, _Dormi Secure_ (sleep in safety). It describes the more important portions of the service, and what makes a good sermon; it gives the Lessons for the Sunday services, the chief articles of the Christian faith, find adds directions for pastoral work and the cure of souls. It is somewhat difficult to describe briefly the character of the preaching. Some of it was very edifying and deservedly popular. The sermons of John Herolt were printed, and attained a very wide circulation. No fewer than forty-one editions appeared. Much of the preaching was the exposition of themes taken from the Scholastic Theology treated in the most technical way. Many of the preachers seem to have profaned their office in the search after popularity, and mingled very questionable stories and coarse jokes with their exhortations. The best known of the preachers who flourished at the close of the fifteenth century was John Geiler of Keysersberg (in Elsass near Colmar), the friend of Sebastian Brand, and a member of the Humanist circle of Strassburg. The position he filled illustrates the eagerness of men of the time to encourage preaching. A burgher of Strassburg, Peter Schott, left a sum of money to endow a preacher, who was to be a doctor of theology, one who had not taken monk’s vows, and who was to preach to the people in the vernacular; a special pulpit was erected in the Strassburg Minster for the preacher provided by this foundation, who was John Geiler. His sermons are full of exhortations to piety and correct living. He lashed the vices and superstitions of his time. He denounced relic
