We’ve heard it so many times that it’s practically part of the Christmas story itself.
The Romans celebrated their seven-day winter festival, Saturnalia, starting on December 17. It was a thoroughly pagan affair full of debauchery and the worship of the god Saturn. To mark the end of the winter solstice, the Roman emperor established December 25 as a feast to Sol Invictus (the Unconquered Sun). Wanting to make Christianity more palatable to the Romans and more popular with the people, the church co-opted these pagan festivals and put the celebration of the birth of their Savior on December 25. For whatever the Christmas holiday has become today, it started as a copycat of well-established pagan holidays. If you like Christmas, you have Saturnalia and Sol Invictus to thank.
That’s the story, and everyone from liberal Christians to conservative Christians to non-Christians seem to agree that it’s true.
Except that it isn’t.
For starters, we should distinguish between roots that suggest a rip-off and roots that suggest a rebuke. The presence of some connection between a Christian celebration and a pagan celebration could imply a synchronistic copy-cat (“Hey, let’s Christianize this popular pagan holiday so as to make our celebration more palatable”), or it could mean a deliberate rejection (“Hey, this pagan holiday is horrible, so let’s put something distinctively Christian in its place”). After the conversion of Constantine in the fourth century, Christians did sometimes adapt and Christianize pagan festivals. Whether they did so wisely and effectively is open to historical debate, but the motivation was to transform the paganism of the Roman world rather than raze it to the ground. Even if Christmas was plopped down on December 25 because of Saturnalia and Sol Invictus, that by itself does not entail that the Christian celebration of Christ’s birth really began as a pagan festival.
But in the case of Christmas, there is good evidence that December 25 was not chosen because of any pagan winter holidays. This is the argument Andrew McGowan, of Yale Divinity School, makes in his article “How December 25 Became Christmas” (first published in Bible Review in 2002). Let me try to distill McGowan’s fine historical work by addressing three questions.
When did Christians first start celebrating the birth of Jesus on December 25?
Unlike Easter, which developed as a Christian holiday much earlier, there is no mention of birth celebrations from the earliest church fathers. Christian writers like Irenaeus (130-200) and Tertullian (160-225) say nothing about a festival in honor of Christ’s birth, and Origen (165-264) even mocks Roman celebrations of birth anniversaries as pagan practices. This is a pretty good indication that Christmas was not yet on the ecclesiastical calendar (or at least not widespread), and that if it were, it would not have been tied to a similar Roman holiday.
This does not mean, however, that no one was interested in the date of Christ’s birth. By the late second century, there was considerable interest in dating the birth of Jesus, with Clement of Alexandria (150-215) noting several different proposals, none of which was December 25. The first mention of December 25 as Jesus’s birthday comes from a mid-fourth-century almanac called the Philocalian Calendar. A few decades later, around AD 400, Augustine would indicate that the Donatists kept Christmas festivals on December 25 but refused to celebrate Epiphany on January 6 because they thought the latter date was a recent invention. Since the Donatists, who arose during the persecution under Diocletian in 312, were stubbornly opposed to any compromise with their Roman oppressors, we can be quite certain they did not consider the celebration of Christmas, or the date of December 25, to be pagan in origin. McGowan concludes that there must have been an older North African tradition that the Donatists were steeped in and, therefore, the earliest celebrations of Christmas (we know about) can be dated to the second half of the third century. This is well before Constantine and during a time period when Christians were trying to steadfastly avoid any connections to pagan religion.
When was it first suggested that Christmas grew out of pagan origins?
None of the church fathers in the first centuries of the church makes any reference to a supposed connection between Christmas and Saturnalia or Sol Invictus. You might think, Well of course they didn’t. That would have been embarrassing. But if the whole point of basing your Christian birth holiday on an existing pagan birth holiday is to make your religion more popular or more understandable, surely someone would say something. Besides, as McGowan points out, it’s not like future Christian leaders shied away from making these connections. Gregory the Great, writing in 601, urged Christian missionaries to turn pagan temples into churches and to repurpose pagan festivals into feast days for Christian martyrs.
There is no suggestion that the birth of Jesus was set at the time of pagan holidays until the 12th century, when Dionysius bar-Salibi stated that Christmas was moved from January 6 to December 25 to correspond with Sol Invictus. Centuries later, post-Enlightenment scholars of comparative religions began popularizing the idea that the early Christians retrofitted winter solstice festivals for their own purposes. For the first millennium of the church’s history, no one made that connection.
Why do we celebrate Christmas on December 25?
The first answer to the question is that some Christians don’t. In the Eastern branch of the church, Christmas is celebrated on January 6, probably for the same reasons—according to a different calculation—that Christmas came to be celebrated on December 25 in the West. Although we can’t be positive, there is good reason to think that December 25 became the date for Christmas because of its connection to the (presumed) date of Jesus’s death and to the date of Jesus’s conception.
There are three dates at play in this calculation. Let’s start with the date of Jesus’s death.
Around AD 200, Tertullian of Carthage noted that Jesus died on the 14th day of Nisan, which was equivalent to March 25 in the Roman solar calendar. In the East, they made their calculation using the 14th day of the first spring month in their local Greek calendar. In the Roman calendar, this was April 6. So depending on who you asked, Jesus died on either March 25 or April 6.
In both the West and the East, there developed the same tradition that Jesus died on the same date he was conceived. An anonymous Christian treatise from fourth-century North Africa stated that March 25 was “the day of the passion of the Lord and of his conception. For on that day he was conceived on the same he suffered.” Augustine in On the Trinity mentioned that same calculation. Similarly, in the East, the fourth-century bishop Epiphanius of Salamis maintained that on April 6 Christ took away the sins of the world and on the same date was “shut up in the spotless womb of the holy virgin.” The fact that this curious tradition existed in two different parts of the world suggests it may have been rooted in more than mere speculation. If nothing else, as McGowan observes, these early Christians were borrowing from an ancient Jewish tradition that said that the most important events of creation and redemption occurred at the same time of the year.
From the date of Christ’s death, to the (same) date of his conception, we can easily see where the date of Christmas could have come from. If Jesus was conceived on March 25, then the best date to celebrate his birth must be nine months later on December 25 (or, in the East, January 6). While we can’t know for certain that this is where December 25 came from—and we certainly can’t be dogmatic about the historicity of the date—there is much better ancient evidence to suggest that our date for Christmas is tied to Christ’s death and conception than tied to the pagan celebrations of Saturnalia and Sol Invictus.

I don’t know about you, but I’m ready to think about something other than politics, read something other than politics, breathe something other than politics.
Before I go any further, it bears repeating: politics matters. As a pastor, I am eager for Christians to be informed and engaged in politics. In fact, after theology and church history, I probably read more on politics, political history, and political philosophy than anything else. I am not against reading, writing, thinking, and speaking on politics.
And yet, I can’t help but question the wisdom of so many Christians—in particular, Christian leaders whose ministries are ostensibly not about politics—voicing specific opinions, sometimes passionately and sometimes frequently, about every political person, place, and thing. I understand that some Christians do punditry, advocacy, and opinion journalism for a living. I’m not surprised when they comment on political matters or weigh in on the events of the day. That’s what they do, and some of them do it really well, helping Christians think Christianly about what they are hearing and reading in the news.
So, again, I’m not against Christians offering cultural and political analysis. I’m not against discipling Christians to see all of life through the lens of Scripture.
What I am against is the instinct shared by too many Christians, including pastors and leaders, that assumes, “If everyone is talking about it, I should probably say something too.”
I worry that people will not first think of gospel convictions or theological commitments when they hear of our churches and ministries, but they will first think of whether we were for or against a certain candidate.
I am nervous that our lines of Christian fellowship will be drawn not according to Reformational principles of ecclesiology, worship, and theology, but according to current expressions of cultural antipathy and identity politics.
I am concerned that weighing in with strong public comments—from both the left and the right—about everything from voter fraud to judicial philosophy to energy policy to why we should all celebrate (when my candidate wins!) and come together in unity (when your candidate loses!)—does nothing to persuade our foes, but much to alienate our friends.
More than anything else, I fear we are letting the world’s priorities dictate what the church is most passionate about.
This isn’t a blanket denunciation of ever saying anything about political issues or political candidates. I have before and probably will again. But perhaps there are questions we should ask next time before joining the online cacophony.
Am I making it harder for all sorts of people to hear what I have to say about more important matters? Think about it: most of us are annoyed when athletes and movie stars feel the need to enlighten us with their political opinions. At best, we roll our eyes and still watch their movies or their games anyway. At worst, we turn them off for good. People will do the same to us. It’s good to think twice before we cash in our goodwill chips, doubling down for or against a particular candidate.
Is my online persona making it harder for my in-person friends to want to be around me? You may feel like, “I only post a few things each day on social media. There is so much more to my life.” True, but what you post on social media is the only part of your life that most of the world knows and sees. People don’t see your fully formed, full-orbed personality and personal life. They see the fifteen things you posted last week, ten of which had to do with politics, seven of which drove half of your friends absolutely bonkers. At the very least, we should consider if adding this stress to family and friends is really worth it.
Am I speaking on matters upon which I do not have special knowledge and for which no one needs my opinion? If my knowledge about something is limited to the three minutes I’ve been angry, or even the 30 minutes I’ve been surfing online, I probably don’t need to download those thoughts to the world.
Am I animated more by what I am reading in Scripture or by what I am seeing on the news and in social media? I’m convinced one of the biggest ways the world is currently shaping the church is by simply setting the agenda for the church’s concerns. We may think we are transforming the world by offering around-the-clock political commentary, but if all we talk about is what media outlets are already talking about, who is influencing whom?
You may argue in reply, I hear you, but the issues are too important. Christians can’t sit on the sidelines as the world argues about the important issues of our day. Fair enough. But consider: is posting your quick thoughts on the daily news cycle really the best way to make a long-term difference? Why not slow down and read some books and comment on those? Or write something online that goes back to first principles? Or write a book if you have opportunity? Or invest in liberal arts education that draws from the best of our Western tradition? Or simply and gloriously disciple young believers to know their Bibles, bear the fruit of the Spirit, and be committed to their local church?
American culture is incredibly diverse. We don’t all watch the same movies or television shows. We don’t all go to church. We don’t all read the same thing or listen to the same music. The one thing that we can all get into is politics, and that’s not healthy. Politics has become the national pastime that brings us all together, only so it can drive us all apart. The task of the church, in this polarized environment, is to slow down, set our minds on things above, and stick to our own script. To be sure, we should not always be silent. But neither should we be the noisiest people in the room, especially when the room tries to tell us what we should be talking about.
Brothers and sisters, it’s OK to have an unarticulated thought. It’s OK to go about our lives in quiet worship and obedience. It’s OK to do your homework, read your Bible, raise your kids, and make your private thoughts prayers instead of posts. Alison Krauss was right: sometimes you say it best when you say nothing at all.

Recently I spoke at the Baccalaureate service for Covenant Day School, a ministry of Christ Covenant Church and the school my own children attend. What follows is a slightly edited version of that message.
I know that I’m speaking to a lot of different ages this morning. I hope you will all be able to pay attention and learn something from this message, but I want to specifically talk to graduating seniors. I know many of you have heard hundreds of sermons over the years–many of them at church, and for some of you, one sermon a week for the past 12 or 13 years at CDS. And now you have one more. But since you are here, you might as well listen and see what God might want to say to you.
This is a season of milestones for many of you. Final papers. Final exams. Last games, last meets, last classes. You’ve worked hard to get to this point. And you are probably working hard for what is coming next. For most of you that’s college or university. You’ll get ready over the summer. You’ll buy some dorm furniture. You’ll say goodbye to your friends. You’ll say goodbye to your parents. You’ll find your way around a new school and a new place. For many of you, it will mean a new city or a new state. You are making preparations for all that lies ahead. After filling out forms, sending in applications, and narrowing down your choices, you finally made your decision. And in a few months, you’ll start something–whether that’s school close by, or school far away, a gap year, or something else.
You are probably tired of making big decisions. But I want to remind you of one colossal decision that is coming your way. The decision doesn’t seem earth shattering. In fact, it seems much less important than a hundred other decisions you’ve had to make in the last year. It’s a decision so much an afterthought for most graduating seniors that many of you have not even considered it.
Here’s the decision you’ll have to make in a few months:
You are living on your own–in a dorm or in an apartment somewhere. You’ve unloaded your stuff. You’ve met your roommate. You’ve signed up for classes. You’ve had a few meals in the cafeteria. You’ve endured days of boring orientation activities. You’ve done some of the awkward pre-planned fun and games. And after a short night of sleep on your first Saturday in this new phase of your life, you wake up Sunday morning. What are you going to do?
Of all the decisions you’ll face this year, the most important one may be whether you get up and go to church on the very first Sunday when no one is there to make sure that you go to church.
Of all the decisions you’ll face this year, the most important one may be whether you get up and go to church on the very first Sunday when no one is there to make sure that you go to church.
I pastored a church in Michigan that was for many years right across the street from Michigan State University. We saw scores of freshmen visit our church that first Sunday on campus. True, many of them never came back. We saw students who started at church and didn’t last. But we rarely saw students who didn’t start at church and eventually made it there. What you do in those first weeks on your own, especially what you do with your commitment to a local church, will set you on a trajectory where Jesus Christ will truly be Lord of your life or where he will be something that you learned as a young person and then left behind.
Listen to Jesus
I know, I know, this is what you would expect a pastor to say to you: “Be sure to go to church, young man! Don’t sleep in on Sunday, young woman!” You may think, “I’m not against going to church, but isn’t my relationship with Jesus the really important thing? I’ll still read my Bible even if I don’t make it to church.” Some of you will be going to Christian colleges, and you’ll have chapel services and Christian roommates and chaplains wanting to meet with you. Others here will be at state schools, and you’ll look to get involved with Cru or RUF or Campus Outreach. That’s great. Praise God for good campus ministries. Praise God for Christian colleges.

But your chapel is not a church. Your weekly Cru meeting is not a church. Your dorm Bible study is not a church. Remember what Jesus said to Peter in Matthew 16, “You are Peter, and on this rock I will build my church, and the gates of hell shall not prevail against it” (v. 18). Jesus never promised to build up a Christian college. He never promised to build a Christian day school. He never promised to build a campus ministry. There is only one institution on earth that Jesus Christ promised to build, and that’s the church.
If you want to be into what Jesus is into, you’ll get into a church.
You need to decide before you leave home, what will I do on that first Sunday morning. Don’t wait until that moment to decide, because you’ll probably decide you’re tired, or you don’t have a car, or you don’t know where to go, or you’ll get to it next week. Decide before that Sunday what you will do on that Sunday. You’ll be making all sorts of plans this summer, and one of the most important decisions you may ever make is what you will be committed to that first week and those first months. Will you get up and go to church–not just chapel, not just campus ministry–but a local church, where the people aren’t all your age, where the music isn’t all your style, where the pastor may not be everything you’d want him to be?
A Grotesque Anomaly
One of the most famous pastors from the last century was John Stott who ministered for many years in London. Like a good, refined, English preacher, Stott was not known for overstatement, which is what makes these words, written a few years before his death, so striking: “An unchurched Christian is a grotesque anomaly. The New Testament knows nothing of such a person. For the church lies at the very center of the eternal purpose of God. It is not a divine afterthought.”
Think of three of the main images for the church in the New Testament. The church pictured as a building, as a bride, and as a body. Christ is the foundation, and the church is the building. Christ is the groom, and the church is the bride. Christ is the head, and the church is the body. Each pair goes together. You are not meant to have one without the other. We are not meant to have Christ without the church.
Would you want your building to have a foundation but no house?
Would you call it a marriage if there was a groom but no bride?
Would you want to carry around a head without the body?
In Greek mythology Perseus was the son of Zeus who killed Medusa, the monster-like Gorgon with a head of hair consisting of snakes. You probably remember the story. If anyone looked on Medusa, he would turn to stone. So when Perseus went to kill Medusa, he had to use his shield to look at her reflection so he could approach Medusa in her sleep and cut off her head. Of course, Perseus still can’t look at her head, so he keeps it in a bag, wrapped up so he doesn’t accidentally see it. Later in the story, Perseus defeats the Kraken by taking Medusa’s head out of the bag and holding it out for the sea monster to gaze upon it and turn to stone. It’s a famous scene depicted in ancient sculpture, in artwork, and now in a number of movies.
It’s rather grotesque when you think about it–carrying around a severed head, lifting up a head without its body. Decapitation is not pretty. If you were into severed heads without their bodies, we would think something was really wrong with you.

Except, it seems, when it comes to our Christian lives. Then we think decapitation is cool. Some of us even think it is positively good and beautifully spiritual. Too many Christians think they can have Jesus without the church. They want the head without the body. They want a decorpulated Christianity. They want a decapitated Jesus.
A Worldview and a Rhythm of Life
I am willing to bet that at some point in your years at CDS you’ve heard the word “worldview.” That word is in the mission statement of almost every Christian school. We want to give students a Biblical lens for looking at everything. We want you to be renewed in your minds so that you view the world not just as someone with a great education but as someone with a distinctly Christian education.
That’s all very important. I hope to impart a Christian worldview to my children. But do you know what may be even more important than getting them to think the right things? It’s getting them to instinctively embrace the right rhythms. The most powerful influences in your life are often the things you don’t even think about, the things you do out of habit, the things you do because you always do them, whether someone makes you do them or not.
We are formed not just by thoughts but by habits–study habits, exercise habits, social media habits, personal hygiene habits. These may not be planks in our worldview, but they shape us just as much or even more. It’s just what we do. And in time what we do becomes who we are. Will the local church be one of your habits in the next year? There are plenty of lukewarm Christians sitting in churches every week across this country. That’s not the goal. But you want to know where you can find passionate, on fire, totally sold-out Christians? In church. In fact, you won’t find them anywhere else.
I said at the beginning that this was a message for seniors, but there are things we all need to hear. For the rest of the high school, when it comes time to make your decision about where to live or where to go to school, you should put church at the top of your list. What eternal good will it do you if you find a school with a great cafeteria, a great campus, a great sports program, and a great academic pedigree, but no great church nearby?
For younger students here, many of you are already very committed to church. You go with your parents every week. There is almost no greater blessing they can give you, almost no better privilege than that. Try to listen as best you can. Try to go in with a good attitude, even when you’re tired or bored. Maybe even ask your parents “Why aren’t we going to church this Sunday” if they aren’t going.
And parents, think about the priorities you are passing down to your children. The good news is you have the biggest influence on whether your child will go to church. The bad news is you have the biggest influence on whether your child will go to church. Your kids will pick up your walk more than your talk. They will follow the example of a lifetime more than the exhortation you give them when you drop them off at college. Are your kids growing up with the habit of regular church attendance? It’s one of the best things my parents ever did for me: they took me to church every week, Sunday morning and Sunday evening. It wasn’t a question. It wasn’t up for debate. It didn’t depend upon the weather. It didn’t depend on whether we had a full day of activities on Saturday. It didn’t depend on whether the sports league had a tournament on Sunday. We went to church, and so it never even crossed my mind that Christians don’t go to church. It didn’t cross my mind that I would go off to college and not go to church. It’s what we did. It’s who we were. It was a non-negotiable rhythm of life.

Finding the Fullness
If you want to be much less of a follower of Jesus Christ five years from now, make church marginal in your life.
Let me conclude with this prediction, which I think is not only supported by personal experience but by the word of God: if you want to be much less of a follower of Jesus Christ five years from now, make church marginal in your life. If you make church an afterthought, you won’t be thinking about centering your life on Jesus five years from now. Don’t give up meeting together as some are in the habit of doing (Heb. 10:25).
Ephesians 1 says, “[God] put all things under his feet and gave him as head over all things to the church, which is his body, the fullness of him who fills all in all” (22-23). Don’t cut the head off of a Jesus. Decide today that you will get up on that Sunday morning and find a good gospel-preaching, Bible-believing church. To be sure, we can meet with God anywhere. But only in the church do we have the fullness of him who fills all in all.
