Pew analyzed audio, video and word count of sermons to estimate the length of sermons in different denominations. The average length of a sermon, researchers found, is 37 minutes, but there are “striking differences” across traditions:
- 14 minutes for Catholics
- 25 minutes for mainline Protestants
- 39 minutes for evangelicals
- 54 minutes for historically black Protestants
Several pastors face pressure to keep trimming the length of sermons to fit people’s minimal attention spans, said the Rev. Tim Keller, the longtime evangelical pastor of Redeemer Presbyterian Church in New York City.
“I don’t think most evangelical pastors are good enough for a 39-minute sermon,” Keller said. “That needs to shorten.”
Keller said when he started preaching 40 years ago, regular church attendance meant someone was in the pew three out of four Sundays. That number has dropped; now, a regular churchgoer appears maybe 1.75 out of four Sundays. He wonders whether that’s because many are listening to sermons via podcast or online streaming as a fallback to showing up for a service.
“If I preach a good sermon, if you’re in the midst of other people, you’re going to remember it more and be shaped by it than if you pick up in a podcast somewhere,” he said. “If it’s totally supplemental, then it’s fine. If, on the other hand, if it undermines the times you’re in Christian community, it’s disastrous.”
In a sermon heard around the world last year, the Rev. Michael Curry, who is the presiding bishop of the Episcopal Church, delivered a message at the royal wedding of Prince Harry and Meghan Markle in about 13 minutes. In that message, he said, he focused on love because it was a universal theme.
“I was very aware in the sermon I was preaching that I couldn’t default to Christian vocabulary,” he said. He said he learned to preach to a broad range of people when he was a minister in southern Ohio, preaching to someone who did domestic work and another person with a PhD.
Curry said he prepares his sermons throughout the week by tapping notes on his iPhone, usually telling a story with one takeaway instead of several.
“A pitfall is to explain a story too much,” Curry said. “If you start explaining a story, you’re messing it up. Your job is to paint the picture, tell the story.”
Historically black Protestant churches have been at the center of many black Americans’ lives, but more black pastors are trimming their services to adapt to people’s attention spans, said Suzan Johnson Cook, who has served as a pastor for the past 30 years.
“One day a week for one hour a week, we deposit not just scripture but history and the application,” said Cook, who was the ambassador for international religious freedom under President Barack Obama. “You have a lot to cover, including social issues.”
The homily is a much-disputed topic in Catholic parishes, and African American parishes often include longer homilies. Many priests believe that the homily, which often includes insight, theological reflection and practical challenges, shouldn’t distract from the Eucharist.
The Rev. John Baldovin, a Jesuit priest who is a professor of liturgy and the sacraments at Boston College, estimates that the average Catholic priest spends two hours preparing for a sermon, devoting the rest of the week to managing the parish or other ministry needs, such as visiting people in the hospital.
“I won’t preach more than 10 minutes on a Sunday,” said Baldovin, who splits his time at parishes near Boston. “You can tell when people are ready for you to land a plane. There’s nothing worse than listening to a plane come into the runway and take off again.”
Pew’s survey also found that certain words and phrases are used more frequently in the sermons of some Christian groups.
Evangelical sermons mention “eternal hell” and phrases about trespassing and sin and salvation more often than other Christian sermons; just under 1 in 10 individual evangelical sermons mentions these terms. Catholic homilies tend to use “Eucharist” and “chalice” more, pointing to the focus in Catholic churches on receiving the Eucharist.
Churchgoers at historically black Protestant churches were eight times as likely than others to hear a phrase including the word “hallelujah.” The language that most distinguishes sermons in mainline Protestant churches include “disciple … betray,” and “bent … look,” phrases tied to biblical stories.
Edwards’s famous sermon, “Sinners in the Hands of an Angry God,” provided imagery that God holds a spider over the fiery pit of hell to describe the wrath of God. Edwards taught that you understand through your senses, not through your reasoning, Keller said, and that the purpose of the sermon is not just to make an idea clear, but to make it real.
“ ’Sinners in the Hands of an Angry God’ is odd; it’s severe, and not how he preached all the time. It’s a model of his method,” Keller said. “The difference between clear and real is preaching that connects the truth to sensory experiences.”
The churches in the survey are not representative of all houses of worship or even all Christian churches in the United States; they make up a small percentage of the estimated 350,000-plus religious congregations nationwide, Pew notes. The churches that post sermons online tend to be in urban areas and have larger-than-average congregations, according to Pew’s report.
