Please Shorten that Sermon

How long should a sermon be? There’s no universal answer to that question – unless you opt for the Holy Spirit gambit and claim you or your pastor preach inerrantly as the Spirit dictates.

The truth is, I can tell a lot about a person’s religious background or current preferences by their honest answer. That’s one of the first lessons a military chaplain learns. Different traditions possess vastly different expectations about sermon lengths.

There are plenty of individual exceptions to the rule, of course. But let me throw out a couple generalizations. People in mainline churches think the sweet spot is around 15 minutes. For many, 12 would be even more desirable, although most can tolerate 20 minutes before beginning incessant time checks on their watches or other devices. In the minds of some, brevity is next to godliness.

For many evangelicals, particularly pentecostals and more fundamentalist communions, a 15 minute sermon is an oxymoron. Anything less than half an hour is simply a devotion or meditation, and any preacher worthy of the title should be able to preach a 45 minute sermon without working up a sweat.

So, in the case of a chaplain preaching for two to three different congregations on a Sunday morning, you would need to tailor your sermons differently for various congregations. Otherwise, if you attempted to strike a happy medium, you ran the risk of having your evangelicals feeling shortchanged and your mainline protestants with eyes glazing over.

Recognizing these differences is helpful, lest we slip into that normal misconception that our assumptions/experiences/logic are shared by others. One evangelical seminary professor, clearly writing for others from a similar tradition as his own, illustrates my point.

The average sermon length, according to one poll, ranges 20 to 28 minutes. If this statistic is accurate, it is a telling indicator of the spiritual depth of today’s churches. Many churches have already discontinued their evening services. With the trend of reducing the length of Sunday morning sermons, our generation is receiving less than half the biblical teaching our parents sat under.

The better a person understands the Word of God, the more they will grow spiritually. . . . I find it difficult to believe that current pastors and their 20 minute sermon-ettes can reach any level of comparable depth to the 80 minutes (or more) pastors used to be given (between the morning and evening services).

I have been pondering this subject not because my own pastor’s sermons are too long. Actually, a few days ago the delightful newsnote, “Today in Christian History,” featured an intriguing note. It is one of Christianity Today’s free newsletters.

It described an incipient Crusade that was derailed before it set out, due to too much of a good thing (too much preaching).

September 26, 1460: Pope Pius II assembles European leaders, then delivers a three-hour sermon to inspire them to launch a new crusade against the Turks. The speech works, but then another speaker, Cardinal Bessarion, adds a three-hour sermon of his own. After six hours of preaching, the European princes lose all interest in the cause; they never mount the called-for crusade.

This is precisely the sort of event I cannot resist learning more about. In short, Pius was a talented orator who had written popular erotic literature during his pre-papal years. Bessarion was a Greek priest who coordinated the effort of Byzantine Emperor John VIII Palaeologus to reunite the Eastern and Western churches to protect Constantinople from the Turks. In 1463, a decade after the city fell to the Ottomans, Bessarion was appointed the Latin Patriarch of Constantinople.

If only Cardinal Bessarion had preached a shorter sermon, perhaps the glorious Hagia Sophia would still resound with the praise of Christ.

How to Measure Sermons

One of the worst ways to weigh a sermon, to consider its worth, is by considering its duration. There is nothing intrinsically better about a sermon that lasts 20 minutes than one of half that length. Barring extremes (e.g. Pius’ and Bassarion’s extended monologues or some jargon-laced, religious pop message modeled after fleeting modern commercials), duration matters little.

I think we could all agree that it is the substance of the message which is shared, that matters. This is where the Holy Spirit leads the way. The sermon should be based on God’s truths. It should be tailored to meet the needs of its particular hearers. And it should be timely, attuned to this specific moment.

Unfortunately, we do tend to associate sermons with extended lectures. In a 1962 letter to one of his regular correspondents, Lewis responds to her question about animals and heaven. After explaining his view, he concludes the letter with an apologetic “But this is turning into a sermon!” In truth, his comments are of the ideal duration to address the question at hand.

And that – an ideal length for the specific context – is the goal for which all preachers should strive.

A Mere Inkling Bonus

I’ve written about the importance of listening to sermons in the past. It includes an entertaining account of C.S. Lewis’ boredom during some of the sermons in his home parish. You can also read here about Lewis’ own experiences as a preacher.

One of C.S. Lewis’ rewarding essays is entitled “The Sermon and the Lunch.” Lewis uses the occasion of a sermon to explore the nature of family. The pastor offers a textbook endorsement of the importance of family, where “we can fling aside the weary disguises of the outer world and be ourselves.” Thereupon, he quickly loses the congregation’s attention.

Lewis’ own thoughts are distracted by his awareness of the pastor’s own family. Having been a guest in the home, Lewis knows the family dynamics fall far short of the ideal he is presenting. However, it is not hypocrisy which disturbs him. It is the fallacious premise upon which the sermon is based. You can read the entire essay at the link on its title in the previous paragraph, or you can listen to a reading of the essay on the link below. Here, however, is the reason for Lewis’ discomfort.

The memory of that lunch worries me during the last few minutes of the sermon. I am not worried by the fact that the Vicar’s practice differs from his precept. That is, no doubt, regrettable, but it is nothing to the purpose. As Dr. Johnson said, precept may be very sincere (and, let us add, very profitable) where practice is very imperfect, and no one but a fool would discount a doctor’s warnings about alcoholic poisoning because the doctor himself drank too much.

What worries me is the fact that the Vicar is not telling us at all that home life is difficult and has, like every form of life, its own proper temptations and corruptions. He keeps on talking as if ‘home’ were a panacea, a magical charm which of itself was bound to produce happiness and virtue. The trouble is not that he is insincere but that he is a fool. He is not talking from his own experience of family life at all: he is automatically reproducing a sentimental tradition – and it happens to be a false tradition. That is why the congregation have stopped listening to him.

Constantine’s Augustae & C.S. Lewis’ Joy

C.S. Lewis considered war a hated necessity in a fallen world. Emperor Constantine I, in contrast, did not shirk from waging violent conflict to reunite the Roman Empire in the early fourth century. What could these two men, humble and proud, have in common?

In a New York Times essay, “C.S. Lewis’s Legacy Lives on, and Not Just Through the Wardrobe,” Mark Oppenheimer compares their influence on the expansion of the Christian Church.

Who, since the time of Jesus and his apostles, has brought more people to Christianity than anybody else?

A short list would include the Roman emperor Constantine, who legalized Christian worship in 313, and Pope Urban II, who began the First Crusade in 1095. But it would also include C.S. Lewis, who moved more hearts with a pen than others have with armies.

Oppenheimer’s Jewish perspective is likely the reason Urban II (c. 1035-1099) finds himself on this short list. After all, the Crusades were intended to liberate the Holy Land from its Muslim conquerors. Other than a handful of the genuinely religious individuals who participated, no historian (much less any educated practicing Christian) would consider the Crusades an evangelistic enterprise.

As for the similarities between C.S. Lewis and Constantine, I am hard-pressed to find many. One, however, is common to many men throughout history. The influence of women in their lives was significant. This is true in terms of both their revered mothers, and their tenacious wives.

Women in Constantine’s Life

Constantine was the first Roman emperor to convert. Because he delivered the Church from persecution and favored the religion within the empire, he is regarded by the Orthodox Church to be a saint. His transitional reign, and the foundation of Constantinople, were monumentally important. But the violence experienced within the imperial family leaves disturbing questions that cannot be answered.

Constantine’s mother, Helena, was a true saint. She lived a devout life and did many good works. Doubtless, she also tempered the volatility of her son.

Constantine had four sons. The first was born to Minervina, a wife or official concubine about whom very little is known.* However, in 307 Constantine followed the common practice of marrying the daughter of a powerful ally, in this case the Augustus (Emperor) Maximian. This wife, Fausta, gave birth to three emperors who succeeded their father and proceeded to battle one another.

The first son, Crispus, was likely the most virtuous of them all. Unfortunately, however, Constantine heeded the lies of his step-mother, Fausta, and had Crispus put to death.⁑

The image of the Roman coins at the top of this column reveals official images of Helena and Fausta. Both of the women had, by the time these were minted, been honored with the title Augusta. The photograph comes from a detailed study of the coinage minted during Constantine’s Vicennalia, which marked the twentieth year of his reign. It features two coins of each, from different mints.

“For Helena,” that author notes, “the reverse always figures Securitas, and for Fausta, either Salus or Spes.” Roman personifications were not actually regarded as “gods,” except by the most superstitious. They were images intended to represent abstract qualities or values. Securitas represented Security with Salus and Spes representing Health and Hope, respectively. The inference here is that Helena represented the stability and authenticity of the dynasty, while Fausta represented its vitality and hope for the future, particularly as she nestles in her arms two future emperors.

Women in C.S. Lewis’ Life

For symmetry, we won’t discuss Minto here. Lewis’ mother and wife did, however, exert a great influence on the man he became. Whereas, with Constantine, one a saint, and the other a murderer, Lewis’ ladies both lived their Christian faith.

Flora Augusta Hamilton Lewis (1862-1908) was the daughter of an Anglican priest in Belfast. (By odd coincidence, her name included Helena’s regal title, Augusta.) Flora was quite gifted, and taught young Jack French and Latin. Her untimely death, during her boys’ childhood, left a last mark on both of them.

My father never fully recovered from this loss. Children suffer not (I think) less than their elders, but differently. For us boys the real bereavement had happened before our mother died.

We lost her gradually as she was gradually withdrawn from our life into the hands of nurses and delirium and morphia, and as our whole existence changed into something alien and menacing, as the house became full of strange smells and midnight noises and sinister whispered conversations. (Surprised by Joy)

Despite the great loss, life continued. Everyone eventually came to view Professor Lewis as a confirmed bachelor. Himself included. That is, until Joy Davidman entered his life. She turned his life upside down. Much has been written about their deep love for one another, and how well suited they were for each other.

Some have criticized Lewis for insensitivity to women. I consider this allegation utterly fallacious. Like all interpersonal relationships in this fallen world, bonds between (and within) genders are complex.

For those who consider Lewis’ personal outlook on male/female roles to be unenlightened, might I suggest you compare them to the example of any other man. Constantine perhaps?


* Minervina may have been Constantine’s wife, or official concubine. Since Crispus was regarded as a fully legal heir, the former is most likely. She may have already died before Constantine strengthened his political position with his second marriage.

⁑ The most probable account is that Fausta falsely accused Crispus of molesting her. After mercilessly condemning his own son, Constantine learned of the deceit and had Fausta executed as well. Crispus already held the rank of Caesar, and was heir apparent to his father. The story is extremely complicated, and heartbreakingly tragic.
