Mithraism
Short answer: Mithraism was a Roman mystery religion centered on the god Mithras, popular especially among soldiers between roughly the first and fourth centuries AD. It is not mentioned anywhere in the Bible. The claim that Christianity copied Mithraism is not supported by the evidence; the two movements are different in origin, date, doctrine, and practice. When Paul stood among the idols of Athens in Acts 17:22-31, he did not borrow from any mystery cult. He named the true God as the unknown one the Athenians already worshiped, called them to repent, and grounded everything in the resurrection of Jesus. The passage gives Christians a model for engaging pagan religion: know it accurately, refuse to flatter it, and point to the Creator who commands all people everywhere to repent.
What Mithraism actually was
Mithraism was one of several mystery religions in the Roman world. It focused on Mithras, a deity depicted killing a bull in the central image of the cult. Worship seems to have taken place in small, cave-like sanctuaries called mithraea, where initiates ate a ritual meal and moved through a series of grades or ranks. It was especially popular among soldiers, merchants, and some officials.
The evidence for Mithraism is mainly archaeological rather than literary. We have shrines, reliefs, inscriptions, and a few hostile comments from Christian writers. We do not have a Mithraic Bible, a written mythology, or a founder narrative comparable to the Gospels. That matters for how confidently anyone can speak about its doctrines. Much popular description of Mithraism today goes far beyond what the sources actually say.
Its origins are debated. Some scholars trace it to Persian worship of a figure named Mithra, while others argue that the Roman cult developed largely in the first century and after. Dating is contested, but the surviving Mithraic material is generally later than the writing of the New Testament. Whatever its roots, Mithraism as a Roman phenomenon is not the backdrop of the apostolic preaching.
Why the word never appears in the New Testament
Readers sometimes ask where Scripture mentions Mithras. It does not. The New Testament names pagan deities such as Zeus, Hermes, and Artemis in Acts, and it refers to idolatry and mystery religions in general terms. But Mithras is absent. That silence is significant when someone claims the apostles were reacting to him.
Acts 17 is the closest the New Testament comes to a sustained engagement with pagan religiosity. Paul is in Athens, a city full of altars, temples, and philosophical schools. If ever there were a place to name a rival mystery god, this was it. Instead Paul speaks of an unknown god and of the Creator who made the world and everything in it.
Paul's approach is not to compare Jesus with Mithras. It is to announce that the God the Athenians ignorantly worship is the one who now commands repentance. The contrast is not between two competing mystery saviors. It is between the living God and everything made by human hands.
The altar to an unknown god in Acts 17
Paul begins with observation. Acts 17:22 says, "You men of Athens, I perceive that you are very religious in all things." He is not flattering them into a mood; he is describing what he saw. The city was saturated with objects of worship, and among them was an altar inscribed to an unknown god.
Paul takes that altar and uses it as a point of contact. He does not treat the inscription as revelation. He treats it as evidence of a gap the Athenians themselves acknowledged. They sensed a deity they did not know. Paul announces that this God, whom they worship without knowing, is the one he proclaims.
This is a careful move. He does not say that all their gods point to Jesus, nor does he endorse the altar as a valid path. He uses their own admission of ignorance to expose what is missing and to introduce the truth. The missionary method is diagnostic before it is declarative.
What Paul says about the Creator and the idols
Paul's speech turns quickly to creation. The God who made the world and everything in it does not live in temples made by human hands, and he is not served by human hands as though he needed anything. The Athenians had built shrines; Paul declares that the Creator cannot be housed by his creatures.
This directly confronts the logic of every mystery cult. Mithraism, like other pagan religion, involved sacred spaces, ritual meals, and images. Paul does not debate the details of any one cult. He undercuts the whole category by asserting that God gives life and breath to all people and does not depend on their offerings.
The same logic appears elsewhere in the New Testament. 1 Corinthians 8:4-6 states that no idol is anything in the world and that there is no other God but one. That is not a compliment to idols. It is a demolition of them. Paul can be calm about pagan religion because he is certain about the Creator.
Repentance, judgment, and the resurrection
The Areopagus speech does not end in friendly dialogue. Paul moves to command. God overlooked the times of ignorance, but now he commands all people everywhere to repent, because he has fixed a day on which he will judge the world in righteousness by a man he has appointed. The proof of that appointment is the resurrection.
Here the speech collides with the audience. Some mock when they hear of the resurrection; others say they will hear more later. The resurrection is not a generic mythic theme that any mystery religion could absorb. It is a public claim about a specific man, at a specific time, with specific witnesses.
This is why Mithraism is not a rival version of the gospel. The gospel is not secret knowledge for initiates. It is news about what God has done in history, announced to everyone, and it calls for repentance. Mystery religion offered hidden rites to a select few. Paul announced a public judgment and a public resurrection.
The alleged Mithras-Jesus parallels
Popular books and internet lists often claim that Mithras was born of a virgin, had twelve disciples, was crucified, and rose again, and that Christianity copied these details. Most of these claims are not found in the ancient evidence. Mithras in the surviving iconography is depicted emerging from rock, not born of a virgin. There is no Mithraic account of a crucifixion or a resurrection.
Some elements do look vaguely similar when stripped of context: a ritual meal, a cave setting, grades of initiation. But similarities in religious practice are common across cultures, and they do not prove literary dependence. The direction of borrowing matters, and Mithraic evidence is generally later than the New Testament documents.
Christians should not be rattled by these comparisons, nor should they repeat them carelessly. The honest answer is that the strong parallels are largely modern inventions. Where real similarities exist, they show that human religion shares patterns, not that the gospel was assembled from them.
How Acts 17 guides engagement with rival religions
Paul's method is instructive. He knows the culture he addresses. He quotes pagan poets without endorsing their theology. He identifies common ground in the doctrine of creation, then presses toward repentance. He does not begin with the temple or the mystery shrine; he begins with the God who made everything.
He also refuses to be vague. He tells the Athenians that their worship is ignorant and that God now commands repentance. Being a careful reader of culture did not make Paul a relativist. He was courteous in tone and uncompromising in content, and the content included judgment and resurrection.
Colossians 2:8-10 warns against being taken captive through philosophy and empty deceit after the tradition of men rather than after Christ. That warning applies to every era, including ours. The church does not need to fear Mithraism or any other ancient cult. It needs to know the Creator, proclaim the risen Christ, and call people to repent.
What this means for Christians today
Mithraism is a useful case study because it shows how quickly popular claims outrun the evidence. Christians can hold their faith with confidence without needing to invent parallels or to panic over them. The New Testament simply does not engage Mithras, and it does not need to. Its message stands on the resurrection, not on comparisons with mystery cults.
Paul's confidence in Acts 17 is not confidence in Athens or in its gods. It is confidence in the God who made the world and who raised Jesus from the dead. That confidence does not require a defensive posture toward every pagan religion. It requires clarity about who God is and what he has done.
So the practical takeaway is twofold. First, learn what the sources actually say before repeating dramatic claims. Second, follow Paul's pattern: observe, name the true God, call for repentance, and point to the resurrection. That is how the church has always answered idols, and it is enough.
Biblical fidelity check
Acts 17:22-31 establishes several things clearly. Paul addresses a pagan city, uses an altar to an unknown god as a point of contact, declares the Creator who does not live in temples made by human hands, and calls all people to repent because of a coming judgment proven by the resurrection. The passage does not mention Mithras, Mithraism, or any specific mystery cult. It does not compare Jesus to a pagan deity or suggest that Christianity borrowed from one.
A common misreading treats Paul's speech as evidence that all religions are pointing to the same God. That is not what the text says. Paul calls the Athenians ignorant and commands repentance, and he identifies the resurrection as the decisive proof. Another misreading treats the altar as a legitimate form of worship that Paul affirms. He does not; he uses it as a starting point to announce the God they do not know. The passage also does not require us to map every pagan religion onto a specific New Testament text; Scripture addresses idolatry in general, and that is sufficient.
Other passages that speak to Acts 17:22-31
Paul's Areopagus speech echoes themes found throughout his letters and the wider New Testament. 1 Corinthians 8:4-6 insists that no idol is anything and that there is one God, which undergirds Paul's confidence in Athens. Colossians 2:8-10 warns against being captured by philosophy and the tradition of men rather than Christ, a fitting caution when studying mystery religions. 2 Timothy 4:3-4 describes people who heap up teachers to suit their own desires, a reminder that religious curiosity is not the same as repentance. And 2 Corinthians 11:3-4 warns that minds can be corrupted from the simplicity that is in Christ, which is exactly the danger when elaborate claims about pagan parallels displace the gospel. Together these passages show that Scripture's answer to rival religion is always the same: the one Creator, the risen Christ, and the call to repent.

Frequently asked questions
Does the Bible mention Mithraism?
No. Mithras and Mithraism are not named anywhere in the Old or New Testament. Acts 17 describes Paul in Athens among many altars and temples, but it does not single out Mithras. The New Testament addresses idolatry and pagan religion in general categories, as in 1 Corinthians 8:4-6, which says that no idol is anything in the world. When people claim a biblical reference to Mithraism, they are reading into the text rather than reading it. The absence of the name is itself important evidence against the idea that Christianity was reacting to or borrowing from this specific cult.
Was Jesus copied from Mithras?
The evidence does not support that claim. The supposed parallels, such as a virgin birth, twelve disciples, crucifixion, and resurrection, are not found in the surviving Mithraic sources. Mithras is typically shown emerging from a rock, and there is no Mithraic death and resurrection narrative. The Roman cult's material remains are also generally later than the New Testament writings. Similarities in ritual meals or initiation grades are not proof of copying. Christians can reject the copying claim honestly, without needing to exaggerate the differences or invent counter-claims of their own.
What can Christians learn from Paul in Acts 17?
Paul models careful engagement. He observes the city, uses an altar to an unknown god as a starting point, and then declares the Creator who does not live in temples made by human hands. He does not flatter the Athenians or treat their religion as an equal path. He commands repentance and grounds everything in the resurrection. For Christians today, that means knowing both Scripture and the culture, refusing to borrow authority from pagan sources, and pointing people to the risen Christ. Acts 17 shows that the church's answer to every idol is the same: the one true God and his appointed judge.
