If you’ve ever scrolled through the long, somewhat dusty list of Roman Catholic leaders, you know the names at the top are usually shrouded in a bit of mystery. St. Peter is the obvious one. Then you get Linus and Cletus—names that sound more like background characters in a Peanuts comic than global religious icons. But things get interesting when we reach the fourth pope, Pope Clement I.
He’s the first one who actually feels like a real person.
History is messy. Honestly, the further back you go, the more it feels like trying to put together a puzzle where half the pieces were eaten by a dog and the other half are from a completely different box. But Clement is different because he left behind a paper trail. We have his writing. We have his struggles. We have a glimpse into a time when being the "Pope" didn't mean living in a palace; it meant trying to keep a tiny, illegal underground movement from imploding.
Sorting through the confusion of the early succession
There is actually a fair bit of debate about whether Clement was really the fourth pope or if he was the second or third. It depends on who you ask and which ancient list you trust more. St. Irenaeus, writing around 180 AD, is pretty firm about the order: Peter, Linus, Anacletus, and then Clement. This is the version the Vatican officially uses today in the Annuario Pontificio.
But wait.
Tertullian, another heavy hitter in early church history, claimed that St. Peter himself ordained Clement as his direct successor. If that’s true, Clement would be the second pope. Jerome also noted that in his day, many people in the Latin-speaking West thought Clement was the immediate successor to Peter. It’s a bit of a historical headache, but most modern scholars stick with the "fourth" designation because Irenaeus’s list is generally considered the most reliable timeline of the Roman succession.
Basically, the title "Pope" wasn't even used back then. Clement would have been known as the Bishop of Rome. He wasn't wearing a triple-tiered tiara or riding in a Popemobile. He was likely a leader of a collection of "house churches" scattered across the city, hiding from imperial authorities and trying to figure out how to keep everyone on the same page.
The letter that changed everything
The biggest reason we care about Pope Clement I today is a document called 1 Clement. It’s a letter sent from the Church in Rome to the Church in Corinth. If you’ve read the New Testament, you know the Corinthians were kind of a mess. Paul had to write to them twice just to get them to stop acting out.
By the time Clement was in charge—around 96 AD—the Corinthians were at it again.
Some of the younger members of the church in Corinth had staged a bit of a coup. They kicked out the older, established leaders (the presbyters) for reasons that aren't entirely clear but seem to involve a lot of ego and "new ideas." Clement wasn't having it. He wrote a massive, sprawling letter to tell them to knock it off and put the old leaders back in power.
This is a huge deal for historians.
It’s one of the oldest Christian documents outside of the Bible. In fact, for a long time, some early Christians actually thought it should be in the Bible. You can still find it in the Codex Alexandrinus, one of the oldest manuscripts of the Greek Bible. The letter is a fascinating mix of Roman stoicism, Jewish scripture, and early Christian theology.
One thing that really stands out in 1 Clement is the tone. He doesn't command them like a king. He appeals to them. He uses a lot of "we" and "us." But—and this is the "expert" nuance—it’s also the first real example of the Church in Rome sticking its nose into the business of a church in a different city. This laid the very early, very shaky foundation for the idea that the Bishop of Rome had some kind of authority over all other Christians.

Was he a martyr or just a man of mystery?
The "Golden Legend" and other medieval stories love a good martyrdom. According to the legends that popped up a few centuries after he died, the Emperor Trajan grew tired of Clement’s success in converting people—apparently even converting the emperor’s own relatives.
The story goes that Clement was exiled to Crimea.
While there, he allegedly found the other prisoners dying of thirst. He prayed, saw a lamb on a hill, struck the ground with a pickaxe, and a spring of water gushed out. This, predictably, annoyed the Romans. They supposedly tied an anchor around his neck and tossed him into the Black Sea.
Is it true?
Probably not. Most serious historians, including the folks at the Catholic Encyclopedia, admit that there’s no mention of this martyrdom in the earliest records. Eusebius, the famous church historian, simply says Clement died in the third year of Trajan's reign (around 101 AD). He doesn't mention anchors or miraculous springs. It’s more likely he died of natural causes, but a quiet death doesn't make for a great stained-glass window design.
The connection to the Roman aristocracy
Here is something that gets overlooked: Clement might have been a big deal in Roman society before he was a big deal in the church.
There was a man named Titus Flavius Clemens who was a Roman consul and a cousin to the Emperor Domitian. Domitian had him executed in 95 AD for "atheism"—which was often a Roman code word for practicing Judaism or Christianity because they refused to worship the Roman gods.
Some people think Pope Clement was this same guy. Others think he was a freedman (a former slave) who belonged to the household of Flavius Clemens and took his name. If he was a freedman, he would have been highly educated, likely managing the business affairs of a wealthy Roman family. This would explain why his writing is so polished and why he seems so comfortable with Roman legal concepts.
He wasn't just some random guy off the street. He was likely someone who understood how power worked in Rome and used that knowledge to organize the early church.
Why you should actually care about Clement today
It’s easy to dismiss guy who lived 2,000 years ago as irrelevant. But Clement represents the moment Christianity stopped being a small Jewish sect and started becoming a global institution.
He was the first one to really hammer home the idea of "Apostolic Succession." He argued that the apostles appointed leaders, who appointed other leaders, and that this chain shouldn't be broken just because some young guys in Corinth wanted a change of pace. Without Clement’s focus on order and structure, it’s possible the early church would have just fractured into a thousand different pieces and disappeared.
He also gives us a look at how early Christians viewed the world. He didn't hate Rome. In his letter, he actually includes a prayer for the Roman rulers. Think about that. He was praying for the very government that was, at times, hunting his people down. That’s a level of nuance you don't often see in the "us vs. them" narratives of history.
What Most People Get Wrong
People often assume the early popes were like the popes of the Middle Ages—men with armies and massive political power.
That’s just wrong.
Clement was likely a coordinator. He was someone who could write a really good letter and convince people to stop fighting. He was a peacemaker in a very violent time. If you look at the Basilica of San Clemente in Rome today, it’s built like a lasagna. The top layer is a 12th-century church. Below that is a 4th-century church. And below that is a 1st-century building that might have been Clement’s home or a "titulus"—a private house used for Christian worship.
It’s a literal physical representation of how the church was built: one layer at a time, starting in the basement of a busy Roman street.
How to Explore the Legacy of the Fourth Pope
If you're interested in the history of the early church or just want to know more about the "real" Clement, here are a few things you can actually do to dive deeper:
- Read the Letter: Don't just take my word for it. You can find translations of 1 Clement online for free. It’s long, but skip to the parts where he talks about the "Phoenix" (yes, he actually uses a mythical bird as a metaphor for the resurrection). It’s wild.
- Virtually Visit San Clemente: Look up 3D tours or photos of the Basilica of San Clemente in Rome. It is widely considered one of the coolest archaeological sites in the city because of those layers I mentioned.
- Compare the Lists: Check out the Liber Pontificalis (The Book of the Popes). It’s an ancient biographical record that gives you the "official" (if sometimes legendary) version of these early lives.
- Look for the Anchor: In religious art, if you see a man with an anchor, that’s Clement. Now you can impress people at art museums with a very specific, very niche bit of trivia.
Clement shows us that the transition from the "Age of the Apostles" to the "Age of the Church" wasn't seamless. It was full of drama, power struggles, and letters written in the middle of the night. He wasn't a myth; he was a leader trying to hold a community together when the world was literally against them.
Next time you hear about the fourth pope, don't just think of a name on a list. Think of a man in a crowded Roman house, dipping a pen in ink, trying to convince people in Greece to just be nice to each other. That’s the real history.

To further your research, look into the writings of Eusebius of Caesarea. His Ecclesiastical History is basically the primary source for almost everything we know about this era. While he lived a couple of hundred years after Clement, he had access to libraries and documents that have since been lost to time, making his accounts the closest thing we have to a contemporary biography. Also, keep an eye out for scholarly debates regarding the Flavian dynasty's connection to early Christianity—it's a rabbit hole that turns a simple religious story into a high-stakes political thriller.
