John Chrysostom and Augustine Practice preceded theory. Certain ideas are to be found in the Church Fathers, and these have been collected by Paniel in the introduction to his work "Geschichte der christlich. Beredsamkeit". The first to treat of the theory of preaching was
John Chrysostom, in his work "On the Priesthood" (
peri Hierosynes). Inasmuch as this contains only reflections on preaching,
Augustine's (
DDC) might be regarded as the first manual on the subject; its first three books deal with collecting the materials for preaching, "modus inveniendi quæ intelligenda sunt", and the last with the presentation thereof, "modus proferendi quæ intellecta sunt". He goes to
Cicero for rules in the latter. He makes a distinction, in which he evidently follows Cicero, between
sapientia (wisdom) and
eloquentia (the best expression of it). Sapientia without eloquentia will do no good; neither will eloquentia without sapientia, and it may do harm; the ideal is sapientia with eloquentia. He adapts Cicero's
ut doceat, ut delectet, ut flectat, changing them to
ut veritas pateat, ut placeat, ut moveat; and lays down these as the rules by which a sermon is to be judged. This work of Augustine was the classic one in homiletics.
Hugh of St. Victor (died 1141) in the Middle Ages laid down three conditions for a sermon: that it should be "holy, prudent and noble", for which, respectively, he required sanctity, knowledge and eloquence in the preacher.
François Fénelon stipulated "must prove, must portray, must impress" (Second Dialogue). Linsenmayer, in his history of preaching, gives information about Humbert, who was a severe critic of the sermons of his time. Trithemius quotes a work by
Albertus Magnus, "De arte prædicandi", which is lost.
Bonaventure wrote "De arte concionandi", in which he treats of
divisio, distinctio, dilatatio, but deals extensively only with the first. on the importance of preaching, and says that it belongs principally to bishops, and baptizing to priests, the latter of whom he regards as holding the place of the seventy disciples. There is a treatise entitled
De arte et vero modo prædicandi attributed to him, but it is simply a compilation of his ideas about preaching that was made by another.
Henry of Hesse is credited with a treatise, "De arte prædicandi", which is probably not due to him. There is a monograph quoted by Hartwig which is interesting for the classification of the forms of sermon:
modus antiquissimus, i. e. postillatio, which is purely the exegetic homily; modus modernus, the thematic style;
modus antiquus, a sermon on the Biblical text; and
modus subalternus, a mixture of homiletic and text sermon.
Jerome Dungersheym wrote a tract
De modo discendi et docendi ad populum sacra seu de modo prædicandi (1513). He treats of his subject on three points: the preacher, the sermon, the listeners. He lays stress on Scripture as the book of the preacher. Ulrich Surgant wrote a "Manuale Curatorum" (1508), in which he also recommends Scripture. His first book gives for material of preaching the usual order
credenda, facienda, fugienda, timenda, appetenda and ends by saying: "Congrua materia prædicationis est Sacra Scriptura." He uses the figure of a tree in laying stress on the necessity of an organic structure.
Humanist writings In the works of the two humanists,
Johannes Reuchlin (
Liber congestorum de arte prædicandi) and
Desiderius Erasmus (
Ecclesiastes seu de ratione concionandi), the return is marked to Cicero and
Quintilian. A masterwork on the art of preaching is the "Rhetorica Sacra" (Lisbon, 1576) of
Luis de Granada, for modern use rather old. The work shows an easy grasp of rhetoric, founded on the principles of
Aristotle,
Demetrius and Cicero. He treats the usual subjects of invention, arrangement, style and delivery in easy and polished Latin. Of the same class is Didacus Stella in his "Liberdemodo concionandi" (1576).
Valerio, in Italy, also wrote on the art of preaching. Another landmark on preaching are the "Instructiones Pastorum" by
Charles Borromeo (1538–84). At his request Valerio,
Bishop of Verona, wrote a systematic treatise on homiletics entitled "Rhetorica Ecclesiastica" (1575), in which he points out the difference between profane and sacred eloquence and emphasizes the two principal objects of the preacher, to teach and to move (
docere et commovere). They were principally ascetic, and in them he regulated the spiritual training necessary for the preacher.
Carolus Regius deals in his "Orator Christianus" (1613) with the whole field of homiletics under the grouping: "De concionatore"; "De concione"; "De concionantis prudentiâ et industriâ". Much is to be found in the writings of
Vincent de Paul,
Alphonsus Liguori and
Francis de Sales, especially in his celebrated letter to
André Fremiot,
Archbishop of Bourges. Among the Dominicans,
Alexander Natalis wrote "Institutio concionantium tripartita" (Paris, 1702). In the "Rhetorica ecclesiastica" (1627) of Jacobus de Graffiis is contained a symposium of the instructions on preaching by the
Franciscan Francis Panigarola, the Jesuit Francis Borgia and the Carmelite
Johannes a Jesu. The "Dialogues" of Fénelon, the works of Blaise Gisbert, Amadeus Bajocensis and Guido ab Angelis have already been referred to. In the nineteenth century homiletics took its place as a branch of
pastoral theology, and many manuals have been written thereon, for instance in German compendia by Brand, Laberenz, Zarbl, Fluck and Schüch; in Italian by Gotti and
Guglielmo Audisio; and many in French and English. ==Relation to secular rhetoric==
