Billions of people hold a view about Jesus of Nazareth. Very few of those views are the same, and the differences are not small details — they are about who he was, whether he died, and whether he rose.
A note on how this is written. I am a Christian, so this page is not neutral about the conclusion. But it is written to be accurate about the facts. Each faith is described as that faith describes itself, using its own sources, not as a caricature of it. If you belong to one of these traditions and find something misstated here, tell me and I will correct it.
I am not trying to win an argument. I am trying to be able to have a conversation.
Catholic and Protestant: the same answer about Jesus
This surprises people, so it is worth stating plainly before anything else.
Catholics and Protestants believe the same thing about who Jesus is. Both hold that he is fully God and fully man, the second person of the Trinity, crucified under Pontius Pilate, died, buried, and raised bodily on the third day. Both affirm the Nicene Creed, which says exactly that.
The Reformation was not a disagreement about Christ’s identity. The differences are real and serious, but they sit elsewhere:
- Authority — Catholicism holds scripture together with sacred tradition, interpreted through the Church’s teaching office. Protestantism holds scripture as the final authority.
- Salvation — Protestantism emphasises justification by faith alone; Catholicism understands grace as received through faith and the sacramental life of the Church.
- The sacraments, Mary and the saints — significant differences in practice and doctrine.
So when someone asks what separates Catholics and Protestants, the honest answer is: not Jesus.
Judaism: not the Messiah, and not divine
Judaism is not a single uniform position — Orthodox, Conservative and Reform Jews differ considerably. But on this question the tradition is broadly consistent.
Judaism does not accept Jesus as the Messiah. The messianic expectation includes things Judaism understands as not yet having happened: the ingathering of the exiles, the rebuilding of the Temple, and an era of universal peace and knowledge of God. On that understanding, the Messiah has not yet come.
Judaism does not accept that God became a man. The centre of Jewish faith is the absolute oneness of God:
Hear, O Israel: the LORD our God, the LORD is one.
Deuteronomy 6:4, the Shema
A divine incarnation is incompatible with that conviction as Judaism understands it. This is not a minor objection to Christianity — it is the objection.
Views of Jesus the man vary. He is generally regarded as a Jewish figure of the first century; assessments range from a teacher within Judaism to a failed messianic claimant. The resurrection is not a claim Judaism engages with as its own question — it is a Christian claim about a Jewish man, and Judaism does not accept it.
It is worth adding, given history: hostility towards Jewish people has often been carried out by people using the name of Christ, and that is a sin against the very thing they claimed to represent. Jesus, his mother and every one of his first followers were Jewish.
Islam: honoured highly, but not divine and not crucified
Islam holds Jesus — Isa — in very high regard. Muslims are required to believe in him. He is one of the greatest of the prophets.
Islam affirms more about Jesus than most people expect:
- He is called al-Masih, the Messiah, in the Qur’an.
- The virgin birth is affirmed. Mary — Maryam — is the only woman named in the Qur’an and is deeply honoured.
- He performed miracles, by God’s permission.
- He is sinless.
- Most Islamic tradition holds that he will return.
But two things are firmly denied, and both are central.
Jesus is not divine, and not the Son of God. In Islam, associating any partner with God is shirk, the gravest sin there is. The Qur’an states God’s absolute oneness directly:
He neither begets nor is born, and there is none comparable to Him.
Qur’an 112:3-4, Surah al-Ikhlas
And the crucifixion is denied. This is the point most Christians do not know about, and it is the sharpest difference of all:
They did not kill him, nor did they crucify him, but it was made to appear so to them.
Qur’an 4:157
Mainstream Islamic understanding is that God raised Jesus to himself rather than allowing him to be killed. So there is no crucifixion, no burial, and therefore no resurrection to affirm or deny.
Side by side
| Question | Catholic | Protestant | Judaism | Islam |
|---|---|---|---|---|
| Who is God? | Trinity | Trinity | One, indivisible | One, indivisible |
| Who is Jesus? | Divine Son, Messiah | Divine Son, Messiah | Not the Messiah, not divine | Prophet and Messiah, not divine |
| Was he crucified? | Yes | Yes | Historically, generally yes | No — Qur’an 4:157 |
| Did he rise? | Yes | Yes | No | No crucifixion, so no resurrection |
| Highest authority | Scripture and tradition, under the Magisterium | Scripture alone | Tanakh with rabbinic tradition | Qur’an and Sunnah |
| How is a person reconciled to God? | Grace through faith and the sacramental life | Grace through faith in Christ | Repentance, covenant faithfulness, God’s mercy | Submission, faith, repentance, deeds, God’s mercy |
Any table this short simplifies. Each tradition contains internal variety, and none of these positions is held identically by everyone inside it. Treat this as the shape of the difference, not the full account.
They cannot all be saying the same thing
It is common and well-meant to say that all religions are really teaching the same thing in different languages. Look at the table and that becomes very difficult to hold.
Jesus is either divine or he is not. He was either crucified or he was not. He either rose or he did not. These are not different emphases on one shared truth. They are mutually exclusive claims about events.
Saying so is not disrespect. It is the opposite — it takes each tradition seriously enough to let it mean what it actually says, rather than flattening all of them into a vague agreement none of them would recognise.
And it means the question cannot be settled by preference. It rests on what actually happened.
Christianity is unusually exposed here, and says so itself:
And if Christ has not been raised, our preaching is useless and so is your faith.
1 Corinthians 15:14
Paul does not argue that Christianity is valuable regardless. He stakes the entire thing on one historical event. That is either a reckless claim or a confident one, but it is not a vague one, and it can be investigated.
Why I wanted to understand this
I should be straightforward about my reason, because it is simpler than it might look.
I wanted to be able to hold a conversation. How can you talk with someone of another faith about what they believe if you do not actually know what they believe? You end up arguing with a version of their religion that only exists in your own head, and they can tell.
And I have to be honest about a limit here: I have not had those conversations yet. I have no Muslim or Jewish friend I have sat down with over this. So this page is research, not experience, and I am not going to present it as more than that.
That is also why it is written the way it is. My instruction to myself was simply to show the facts and let the Bible do the rest. I am not interested in scoring a point against anyone’s faith. If you are Muslim or Jewish and you have read this far, I hope you found yourself described fairly — and if you did not, I would genuinely rather be told than be wrong.
What I do believe is on the rest of this site, stated openly. I am not hiding it here. I just do not think misrepresenting someone else’s position has ever persuaded anybody of anything.
Frequently asked questions
Do Muslims believe in Jesus?
Yes. Muslims are required to believe in Jesus — Isa — as one of the greatest prophets. Islam affirms his virgin birth, his miracles and his sinlessness, and calls him al-Masih, the Messiah. It denies that he is divine and denies the crucifixion.
Do Jewish people believe Jesus existed?
Generally yes, as a Jewish man of the first century. Judaism does not accept him as the Messiah or as divine, since the messianic age it expects has not arrived.
What is the main difference between Catholics and Protestants?
Not Jesus. Both affirm the Nicene Creed and the same understanding of Christ. They differ on authority, on how grace is received, and on the sacraments, Mary and the saints.
Does Islam accept the crucifixion?
Mainstream Islam does not. Qur’an 4:157 states that Jesus was not killed or crucified but that it was made to appear so, and that God raised him to himself.
Do all religions worship the same God?
They make different and incompatible claims about God’s nature — particularly whether God is triune and whether he became man. Those claims cannot all be true at once, whatever sincerity is shared.
Why does it matter what people believe about Jesus?
Because the claims are about events rather than preferences. Christianity in particular stakes itself on the resurrection — 1 Corinthians 15:14 says that if Christ was not raised, the faith is useless.
