That is religion, not racism. Khaybar is history, Al-Aqsa is being stormed, and the Jews did reject Christ.

The fuller answer

You need no theological training for any of this, and nobody is asking you to arbitrate between religions. You are answering particular claims made by particular movements, and you can decline any part of it.

The rule that governs everything below, and it is meant. This entry is about specific theological claims and the movements that make them. It is not about Islam and it is not about Christianity. Most Muslims hold none of the Islamist material here, and most Christians hold none of the Christian material. An argument that slides from a movement to a faith has done the thing this page exists to oppose.

The distinction that decides your response

Two things arrive dressed alike.

One is theological antisemitism: a claim about what Jews are, rooted in scripture or in sacred history, which no fact about any government could alter. The other is religious language used about a political dispute. Anger about a place, about access, about policing, spoken by religious people in the vocabulary they actually have.

Argue the political version on the facts, and you can often win. Name the theological version, and decline to treat it as a policy disagreement, because treating it as one flatters it.

The test is what would settle it. If every contested fact went the other way, would the claim change? “Police went into the mosque in riot gear” is a claim about an event. “The army of Muhammad is returning” is not.

The Christian side

This part comes first because it is the easiest to win and the most likely to be fumbled. The medieval material, including the blood libel, has its own entry.

Supersessionism is the teaching that the church replaced the Jews, inheriting a covenant they forfeited. It is not fringe. The Church of England’s 2019 teaching document is blunt about it. Christian theology, it says, “played a part in the stereotyping and persecution of Jewish people which ultimately led to the Holocaust”.

The deicide charge is the accusation that the Jews killed God. Its afterlife is long, and it is where you hold the strongest cards, because the repudiations are formal, dated and published.

• The World Council of Churches, at New Delhi on 29 November 1961. Member churches were told not to present the crucifixion so as to fasten responsibility on the Jewish people of today.
• The Second Vatican Council, on 28 October 1965. The passion “cannot be charged against all the Jews, without distinction, then alive, nor against the Jews of today”. And Jews are not to be presented “as rejected or accursed by God”.
• The Evangelical Lutheran Church in America, on 18 April 1994. It repudiated Luther’s anti-Jewish writings and called antisemitism “a contradiction and an affront to the Gospel”.

That list is the whole answer, and it fits in one sentence.

“Your own church answered that. If you’re Catholic it’s Nostra Aetate in 1965. If you’re not, the World Council of Churches got there in 1961.”

Notice what that sentence does not do. It does not call anybody an antisemite, it does not put your judgement against his faith, and it does not ask him to take your word for anything. It hands him a document his own tradition wrote and lets him go and read it. Most Christians who repeat this material were never taught that their church had settled it sixty years ago, and being shown that is a completely different experience from being accused.

Use it as an offer. It is the single most effective sentence on this page.

“Jesus was a Palestinian.” Answer accurately and briefly, because the sneering version is a trap.

Jesus was a Jew, circumcised on the eighth day and going up to Jerusalem for the festivals. He was executed under a placard naming him king of the Jews. In his lifetime the Roman province was Judaea, renamed after the Bar Kokhba revolt of 132 to 135, roughly a century after his death.

Now the part that will be used against you if you overreach. The name Palestine is older than Hadrian, and Herodotus used it in the fifth century BCE. So “Palestine did not exist” is not a sentence you want to be holding. What survives is narrower: the phrase is a problem when it is doing the work of saying he was not Jewish. If somebody means he lived under military occupation, argue the analogy rather than the map.

Christian Zionism, honestly. Some Christian support for Israel rests on a theology in which Jews have a part in somebody else’s story. In some versions that story ends badly for them. Accepting help does not require endorsing the reason for it, and refusing every offer whose theology you dislike would leave you with few friends. The guide on talking with conservatives works through where the line falls.

Khaybar

The chant is “Khaybar, Khaybar, ya yahud, jaish Muhammad sawfa ya’ud”. Jews, remember Khaybar, the army of Muhammad is returning.

Khaybar was an oasis north of Medina, home to established Jewish tribes, taken by Muhammad’s forces in 628. The Anti-Defamation League’s reading is careful. The chant “can be perceived as a threat of armed violence or forcible expulsion against Jews today”. It also recasts a territorial conflict as a religious war.

Notice the grammar, because it is the whole argument. The chant is addressed to Jews, in the second person, not to Israel or to a government. What is promised is a repetition of what happened to a Jewish community in the seventh century.

It has been heard across Europe and North America, and in Britain since at least 2010, at the Oxford Union.

Where advocates get caught. Prosecutions have been brought over this chant, in Britain and in Belgium. In Britain juries have acquitted twice, most recently in December 2025. So “that is a crime” is a line you cannot carry, and this site states no country’s law. What holds is narrower: prosecutors in England have called the chant antisemitic, and juries have declined to convict for it.

People also chant things without knowing what they mean. Somebody repeating a line from the front of a march is not the person who wrote it. Ask before you assert. “Do you know what Khaybar was?” gets further than any accusation.

And the movement literature. Article Seven of the Hamas covenant of 1988 quotes a hadith. In it, stones and trees call out that a Jew is hiding behind them, so he can be killed. Nothing there is about land or borders. Compare a complaint about a checkpoint: one is answerable by a political settlement and the other is not.

Al-Aqsa, and the facts almost nobody can state

Start here: the attachment is real. Al-Aqsa is the third holiest site in Islam, prayed in by tens of thousands. Anger about what happens there is not a manufactured emotion, and an argument that opens by minimising it has lost the room. The dispute is about the factual claims, so know them.

Administration. The Jerusalem Islamic Waqf runs the compound day to day. It is controlled and funded by the Jordanian government and employs around 900 people. This dates from 1967, when Israel took the Old City and the defence minister Moshe Dayan left the Jordanian religious authority in place. The 1994 Israel-Jordan peace treaty gave priority to Jordan’s historic role at the Muslim holy places.

Policing. Israel holds security responsibility and controls access, while inside the gates the Waqf has near total control. Non-Muslim visitors enter through one gate, the Mughrabi Gate, at set hours, under police supervision.

Prayer. Under the arrangement as it stood from 1967, non-Muslims may visit and may not pray. Jewish visitors have been removed or detained for carrying prayer books, for wearing tefillin, for bowing or swaying.

And the part you have to say yourself, before anybody says it for you. That arrangement is moving. On 21 January 2026 Israeli police for the first time let Jewish visitors carry a printed prayer sheet onto the compound. It had to be prepared in advance and handed out at the entrance. Three months earlier, on Yom Kippur, people had been arrested for carrying exactly that. Whatever you think of it, an advocate who insists nothing has moved is repeating a line that stopped being true.

The real events, too. In April 2023 Israeli police entered the Qibli prayer hall during Ramadan, used stun grenades, and detained hundreds. The police account is that masked youths had barricaded themselves inside with fireworks, clubs and rocks. Jordan called it a storming of the mosque. You gain nothing by knowing one of those and not the other.

So where is the antisemitism? Watch for two shifts. The actor becomes “the Jews” rather than the Israeli police, and the language becomes defilement rather than trespass. At that point a dispute about policing has become a claim about what Jews do to holy things. The word to listen for is defiled. It does not describe a policy.

The lineage is not obscure. The claim that Jews were about to destroy Al-Aqsa was circulated by Arab leaders in 1929. The riots that followed killed more than 60 Jews in Hebron alone, ending a community of centuries.

Lines you can say

“What would settle this? If every fact about that mosque went your way tomorrow, would the claim change?”

“Do you know what Khaybar was? It’s a battle in 628. The chant isn’t about Israel, it’s addressed to Jews.”

“The site is run day to day by the Jordanian Waqf. Israel does the security. That’s been the arrangement since 1967.”

“Jews haven’t been allowed to pray there, and that’s now changing. I’d rather argue about the change than pretend it isn’t happening.”

“Your own church answered that. If you’re Catholic it’s Nostra Aetate in 1965. If you’re not, the World Council of Churches got there in 1961.”

“He was a Jew from Galilee, and the province was called Judaea in his lifetime. If you mean he lived under occupation, say that and I’ll argue it.”

Pick one, and put a date on it

Pick one and put a date on it.

If somebody chants or posts Khaybar in front of me this week, then I will ask what Khaybar was before saying anything about what it means.

If Al-Aqsa comes up, then I will state administration, policing and prayer in that order, and say plainly that the prayer arrangement is changing.

If a Christian tells me the Jews rejected or killed Christ, then I will ask what his own tradition teaches, and name the document rather than the person.

And the coping plan, because this one is predictable. If I am accused of attacking somebody’s religion, then I will name the movement and the document I am talking about, and say out loud that most people of that faith hold none of it. If I cannot name the document, I will drop the point.
