If we attend carefully to these speeches, we can learn a lot about good preaching, but also a lot about the nature of Christianity.
I have always loved the Acts of the Apostles and have often recommended it to those who are approaching the Bible for the first time. Filled with colorful narratives, adventure, martyrdom, persecution, journeys by sea, etc., it makes for stimulating reading indeed. But I love it especially because it shows us the excitement of being a follower of Jesus. Long before there were parishes and dioceses and the Vatican and other institutional structures, there was this band of brothers and sisters who were so overwhelmed and energized by the fact of the resurrection that they went careening around the world and to their deaths with the message of Jesus.
It also features some wonderful exemplifications of Christian preaching, for it relates to us some of the earliest kerygmatic proclamations of the apostles. If we attend carefully to these speeches, we can learn a lot about good preaching, but also a lot about the nature of Christianity. A particularly fine example is the sermon given by St. Peter on Pentecost morning and described in the second chapter of the Acts of the Apostles. We hear that Peter stood up with the Eleven and raised his voice. First lesson: all legitimate Christian teaching and proclamation is apostolic, which is to say, grounded in the witness of the first intimate followers of Jesus. Bishops are entitled to preach precisely because they are successors of the apostles; priests and deacons are formally commissioned to preach by bishops. This is to assure that what preachers say is not just a matter of private opinion or the fruit of the present cultural consensus, but is rather rooted in the experience of those who knew Jesus personally.
So what does apostolic preaching sound like? Peter says, "Let the whole house of Israel know for certain that God has made him both Lord and Messiah, this Jesus whom you crucified." Notice, first, the strength, confidence, and edginess of this proclamation. There is nothing weak, vacillating, or unsure about it. This is not a preacher sharing his doubt with you or reveling in the complexity and multivalence and ambiguity of faith. This is a man speaking (in a loud voice) about his absolute conviction. And what is he convicted about? "That God has made him both Lord and Messiah, this Jesus whom you crucified." Christos, the Greek term for Messiah from which we derive the English word Christ, has the sense of anointed, which implies the new David, which means the fulfillment of the expectation of Israel. Good preaching always puts Jesus in relation to Israel, for he makes sense only kata ta grapha (according to the Scriptures). A Jesus abstracted from the history of Israel devolves in short order into a mere religious teacher or teacher of timeless spiritual truths.
And not only is he Christ; he is also Kyrios (Lord). This term had, at the time of Peter and Jesus, both a Jewish and a Roman sense. On the Jewish reading, it designated Yahweh, the God of Israel, for Adonai (Lord, in Hebrew) was the typical substitute for the unpronounceable tetragrammaton, YHWH. Paul, who continually calls Jesus "Lord," says that Jesus was given the name above every other name, by which he means the name of God. Preaching that leaves the divinity of Jesus aside or in the shadows is, therefore, not Apostolic preaching. Now Kyrios also had a Roman sense, since Caesar was called kyrios, meaning the one to whom final allegiance is due. Do you see how edgy and subversive it was to declare that Jesus is Lord, and by implication, Caesar is not? And do you see why those who made that claim usually ended up imprisoned and/or put to death? A twentieth century Anglican bishop memorably expressed the insight as follows: "When Paul preached, there were riots; when I preach, they serve me tea."
Notice, next, that Peter is not tickling the ears of his hearers: "God has made both Lord and Christ this Jesus whom you crucified." He's not pulling any punches or trying to win friends and influence people. About as bluntly and clearly as he possibly can, he names the sin of his audience. And this is precisely what "cuts to the heart" of his hearers. Trust me when I tell you that abstract spiritual principles, tired bromides, and timeless moral truths don't cut people to the heart. And so they cry out, "What are we to do?" Peter's sermon continues: "Repent and be baptized for the forgiveness of your sins." Every truly evangelical sermon should be a call to repentance, to turn one's life around. If it doesn't lead to contrition and a conviction to change, it has not cut to the heart. Mind you, this doesn't entail moralizing in a brow-beating way, but rather the presenting of the message of Jesus in such a clear and compelling way that people naturally see how they've fallen short and want to change.
Peter concludes: "Save yourselves from this corrupt generation." Followers of Jesus are a holy nation, a people set apart. We have renewed minds and wills; we should profile ourselves distinctly against the backdrop of the world. If we think and act like everyone else, we haven't taken in the Gospel. Relatedly, if all we hear from the pulpit is what can be heard on talk-shows and in discussion groups and in political conversations, we haven't heard the Gospel. Finally, we are told that, "Three thousand persons were added [to the Church] that day." I know that everyone and his brother tells us not to worry about numbers and there is indeed truth to that. For God wants us to be, not successful, but faithful, as Mother Teresa said. However, like it or not, the Bible is interested in numbers. And good preaching, if it is truly evangelical, is meant to draw people into the Church. That they are staying away from the Church in droves today says, I would suggest, something rather negative about the quality of our preaching.
To all preachers, I might recommend a careful consideration of the kerygmatic sermonizing in the Acts of the Apostles. If you preach like Peter, they might not serve you tea after every homily, but they will know that they've been cut to the heart.
