Preaching

← Encyclopedia

Preaching is the public proclamation and exposition of religious teaching before a gathered assembly: the spoken word offered as instruction, exhortation, and address, standing alongside the read scripture as a distinct act of worship. Its commonest forms are the sermon and the homily — a sustained discourse, usually by an authorized speaker, that explains a sacred text or presses its claim upon those listening. The distinction between the two is old and exact. Homilia is a Greek word for conversation or familiar discourse, and from the time of Origen it named a running commentary on a passage of scripture, without formal introduction, division, or conclusion, whose aim was to draw out both the plain and the deeper sense of the text verse by verse. The sermon, by contrast, takes up a chosen theme and gathers scripture to it. One follows the text; the other follows an argument. Both rest on the same conviction: that the written word is not finished until it is voiced.

The synagogue and the derashah

The practice has roots in the synagogue, where the reading of the Law and the Prophets was followed by an interpretive discourse, the derashah. The pattern is traced to Ezra, who in the fifth century before the common era read the Torah aloud and rendered it into the vernacular so that the people standing in the assembly could grasp what was read. What began as translation hardened into a genre. After the appointed Torah portion came a reading from the Prophets, the haftarah, and after the readings the darshan would rise and expound — by plain explanation, by allegory, by parable, by anecdote drawn from the stock of remembered story. Long before the Christian era this interpretive discourse had become an integral part of the liturgy of the synagogue, the moment in worship when the closed scroll was reopened in living speech and bent toward the condition of those who heard it. The architecture is the one all later preaching would inherit: a fixed text, read; and then a free word, spoken, that claims to release what the text holds.

Kerygma: the announcement of an event

Early Christianity took up that pattern and made it central, but it changed the content of the spoken word at the root. The apostolic proclamation, the kerygma, was not in the first instance the exposition of a book but the announcement of a thing that had happened. The Greek noun comes from the verb for what a herald does — to cry out, to proclaim aloud the news that something has occurred — and the word still carries that sense of heralding rather than explaining. Paul the Apostle treats this proclamation as the gospel itself: the message of a death and a rising, set before the hearer as an event demanding a verdict, not a system inviting study. Scholarship has fixed the distinction sharply. The English theologian C. H. Dodd, in The Apostolic Preaching and Its Developments (1936), reconstructed from the speeches in Acts and the letters of Paul a stable core of proclamation and set it apart from didache, the settled teaching that came afterward to instruct those already won. Kerygma announces; teaching unfolds. The order matters to the tradition: the Word is first cried, and only then explicated. In this frame preaching is not commentary that might or might not be added to the reading. It is the act by which an event that happened once is made to happen again, addressed now, to these ears.

The late-antique homily and the patristic preachers

By late antiquity the homily had become a settled liturgical genre, and the great preachers of the patristic age — figures whose sermons survive in volume — were prized as much for eloquence as for doctrine. John Chrysostom, trained in rhetoric at Antioch and later archbishop of Constantinople, earned the name Chrysostomos, “golden-mouthed,” from generations who had only the homilies to go on; he preached through whole books of scripture in sequence, on Genesis and the Psalms, on Matthew and John and the letters of Paul, and the crowds that filled the church applauded his cadences aloud, to the unease of clergy who thought the sacred word should not be received like a performance. The reach of preaching into the structure of worship was now total: the homily belonged to the rite, an office of the bishop or presbyter, not an optional grace.

The Latin West gave the act its theory. Augustine of Hippo, in the fourth and final book of De doctrina christiana, turned the inherited apparatus of classical oratory to the service of the Christian preacher, taking over Cicero’s threefold office — to teach, to delight, to move — and subordinating it to the truth the preacher served, so that eloquence became the handmaid of doctrine rather than its rival. Here the Word is understood as voiced: the divine utterance that Hellenistic theology held to run through the world is what the human preacher, in his lesser register, is taken to be carrying into the room. The settlement Augustine reached — that rhetoric is licit when it serves the message and corrupting when it serves the speaker — governed Christian thinking about the act for a thousand years.

The medieval craft: ars praedicandi and the friars

The medieval West produced a whole literature of instruction in the craft, the ars praedicandi. Between the early thirteenth and the late fifteenth centuries a new kind of discourse came into vogue — the scholastic or university sermon, also called the thematic or “modern” sermon — and with it a body of manuals teaching how to build one. The technical use of ars for preaching appears with William of Auvergne, whose Summa de arte praedicandi belongs to the second quarter of the thirteenth century; Thomas of Chobham wrote a Summa of his own, perhaps slightly earlier; and Robert of Basevorn’s Forma praedicandi (1322) became the most systematic of the genre. The form they taught was rigorous: a thema, a brief string of words taken from scripture, was stated, then divided into parts, and each part developed in turn, the whole bound by verbal concordances and rhetorical figures into a structure that owed as much to the lecture hall as to the pulpit. This was preaching as architecture, learned and laid out in advance, the opposite pole from the homily’s free pursuit of the text.

Against that learned form, and partly out of it, the thirteenth-century friars rebuilt the sermon into a mobile, popular thing. The two mendicant orders made preaching their reason for being — the Dominicans constituted as an Order of Preachers, the Franciscans carrying the word out of the cloister entirely. The Franciscan ideal joined the spoken word to the lived poverty of the speaker; the contemplative summit of that tradition, mapped in Bonaventure’s Itinerarium mentis in Deum, set the affective ascent of the soul above mere instruction, and its preaching aimed less to inform than to move the will toward God. Carried into marketplaces and open fields, addressed to crowds who could not read the text being preached, the friars’ sermon recovered something of the herald’s original function: not the patient exposition of a page but the public crying of a claim, delivered where the people already were.

The khutba: a comparable office in Islam

In Islam the khuṭba holds a comparable place. Delivered from the minbar — a pulpit, often high and richly built, that only the preacher ascends — the khaṭīb addresses the assembly at the Friday congregational prayer and on the great feasts, his sermon preceding rather than following the formal act of worship and counting as a condition of its validity: the prayer is not complete without it. A set of fixed rubrics surrounds the office. The preacher’s dress and posture are prescribed; he stands and sits in a fixed sequence; tradition directs him to lean on a staff, a sword, or a bow as he speaks. He admonishes the gathered to piety, prays on behalf of the faithful, and recites a portion of the Qur’an, and through long centuries he named the reigning sovereign in his prayer — so that to be named in the khuṭba was a public token of legitimate rule, and to be dropped from it a public deposition. Here the spoken word is welded to the act of worship and to the political order at once, exhortation and allegiance and prayer pronounced in a single voice.

What preaching is held to do: the doctrinal contrast

What preaching is understood to do differs sharply by tradition, and the differences are doctrinal rather than incidental. For much of Catholic and Orthodox practice the sermon instructs and edifies, but the sacrament remains the principal channel of grace; the preached word prepares and explains, while the grace itself is conveyed by the rite — at the altar, in the communion of the faithful with the body offered there. Preaching in this frame is essential and yet penultimate, the lamp that lights the way to a gift it does not itself bestow.

The Reformation reordered that priority. Martin Luther held that the church lives by the word preached, and located the audible gospel — viva vox evangelii, the living voice — at the center of its life; the Augsburg settlement defined the church itself as the assembly where the word is purely preached and the sacraments rightly administered. John Calvin, preaching through book after book of scripture in continuous sequence from the pulpit of his church in Geneva across more than four thousand sermons, treated the word as the instrument God uses to address the gathered congregation directly. The boldest formulation came from the Reformed side: the Second Helvetic Confession of 1566 set at the head of its first chapter the claim that the preaching of the word of God is the word of God — that when a lawfully called preacher proclaims it in the assembly, the very word of God is proclaimed and received by the faithful, the same God who once spoke through prophets and apostles speaking now through the human voice. With that, preaching ceased to be a means of instruction pointing toward grace and became a means of grace in its own right, and the pulpit moved, physically and theologically, toward the center of the building, where the altar had stood.

Among the Quakers the logic runs the other way entirely. Robert Barclay, in the eleventh proposition of his Apology for the True Christian Divinity (1678), argued that true worship arises only from the inward and immediate moving of the Spirit, and that prepared prayers and prearranged sermons are “creaturely” interpositions — the work of human will thrust between the soul and the Light that would teach it directly. So Friends set aside trained and scheduled preaching altogether. They gather in silence and wait; and if one present is moved, that person rises and offers vocal ministry — prayer, prophecy, scriptural exhortation — and then the silence returns. Here the wager of the others is inverted: the danger is not that the word will go unspoken but that it will be spoken too readily, by the speaker’s own resolve rather than the Spirit’s prompting. Where the Reformed pulpit makes the prepared word the surest channel of grace, the waiting meeting treats every prepared word as a possible obstruction to it.

The wager beneath the act

Across these settings the constant is a claim about words. Preaching assumes that a teaching does not merely need to be recorded but to be voiced, pressed, and renewed in each hearing — that the address itself accomplishes something the text on the page does not. The scroll is read the same in every assembly; the derashah is never twice the same, because it is bent each time toward the people in front of it. The herald’s cry is not information that could as well arrive by letter; it is an event staged in the room, demanding a verdict from the particular ears that catch it. The friar in the marketplace, the khaṭīb on the minbar, the Reformer in the high pulpit, the Friend rising out of the silence — each acts on the same conviction across every doctrinal divide: that a teaching held only in writing is a teaching half-kept, and that what is written must be said, and said again, into each new gathering, or it does not fully live. The act is a standing bet that meaning is not finished in the text but completed in the speaking — that the word, to do its work, must be carried by a voice into the hearing of the assembled, and pressed there, now, upon the living.
