Prof. Carr’s overview of the history of preaching demonstrates a pattern of continuity and change that has nourished and edified the church over the centuries. While the main thrust of Gospel proclamation has been constant throughout the history of preaching from the time of the early church through the twentieth century, the addition of innovations in preaching has assured that Gospel proclamation remains attuned to the culture and is refreshed with each passing generation. The innovations discussed by Carr can be classified into three broad categories: technological innovations, stylistic innovations, and cultural innovations. Technological innovations have been most readily apparent in the twentieth century with the introduction of new information technologies. Prof. Carr identifies preachers who were pioneers in radio and television ministries. The advances in the internet, furthermore, are ushering in a new era of transformation in preaching aided by technology. But these more obvious drivers of technological innovation in preaching, Prof. Carr aptly shows, are matched by equally significant technological innovations in years past. Charles Spurgeon, for example, exploited the technologies of his day by printing and distributing his Penny Pulpit pamphlets throughout England and indeed around the world. The formation of homilaries was an even earlier technological innovation that affected the history of preaching in a profound way. Stylistic innovations are also evident throughout the history of preaching. Preachers such as Billy Sunday and Aimee Semple McPherson introduced significant innovations in preaching style by bringin in improvisation, drama and other attractive stylistic elements. Martin Luther King Jr popularized a stylistic innovation that had emerged years earlier in the preaching of John Jaspers. Charles G. Finney introduced new stylistic elements in preaching by establishing the anxious bench and giving listeners greater participation in the sermon. Calvin also innovated preaching by making the sermon, rather than mass, the center of the worship service. Cultural innovations have been a staple of preaching since the early years of the church. Throughout the history of preaching we find cultural innovations shaping the proclamation of the Gospel in numerous ways. Savonarola, for example, stands out as a preacher who brought social justice issues into the preaching of the Word in response to the epoch of social change in which he preached. This cultural change was enduring and can be seen in the legacy of other preachers such as Martin Luther King Jr. Dwight Moody, on the other hand, transformed preaching through the introduction of a common and colloquial style in the pulpit. The twentieth century ushered in other cultural innovations in preaching – most notably, the inclusion of women in the pulpit. Whether driven by technology, style or culture, the innovations in preaching over the centuries have enriched the proclamation of the Gospel, extended its reach and edified the church. Prof. Carr summarizes the course by saying that what the world needs today is more preachers and not less. I would add that as more preachers are added to the fold, we can expect further transformations and innovations in preaching due to technological, stylistic and cultural shifts. As long as the Gospel is proclaimed, moreover, we should resist the tendency to reject these innovations and instead maintain an eye towards the ways that innovations are enriching preaching and expanding the reach of the Gospel.
