Christian attitudes in the US have improved considerably toward Jews over recent decades.

In the Catholic world, good will followed 1965’s Vatican II, which condemned anti-Semitism and called Jews their “elder brothers.” And the good will has been not only on display but actively demonstrated on issues of common interest, from raising alarm about Islamist terrorism to promoting school choice. The Catholic Church has maintained diplomatic relations with Israel since 1993.

American evangelicals are particularly strong supporters of Israel; a majority believe the Holy Land belongs to the Jewish people. Other Protestant denominations have formally renounced anti-Semitism and affirmed Hashem’s covenant with the Jewish people.

But that good will is not shared by two self-promoting Christians who have been prominent in the public eye.

Back on February 9, a meeting of the White House’s Religious Liberty Commission focused on combating anti-Semitism and upholding religious freedom went fine, well, until it ran off the rails.

One member of the commission, conservative activist Carrie Prejean Boller, used the meeting to attack “Zionism”—i.e., Israel and its supporters—and defend commentators Tucker Carlson and Candace Owens. (The former promoted Nazi apologists and Holocaust deniers; the latter encouraged her followers to read a text claiming that Jews ritually murdered Christians and drank their blood. As Mr. Carlson might drolly comment, Just saying.)

Ms. Prejean Boller proclaimed that her Catholic faith—to which she converted last spring—informs her anti-“Zionism” convictions.

“I’m a Catholic,” she declared, with zeal not uncommon to neophytes, “and Catholics do not embrace Zionism, just so you know.

“So,” she sneered at several victims of anti-Semitism who had testified at the meeting, “are all Catholics anti-Semites?”

Two days later, the commission chairman booted her for trying to “hijack” the hearing for her “own personal and political agenda.” She then accused the commission of having “a Zionist agenda,” and, in intrepid martyr mode, posted on social media that “I would rather die than bend the knee to Israel.”

Mr. Carlson, for his part, in his recent interview of US Ambassador to Israel Mike Huckabee, repeatedly took pains to stress his own Christian bona fides.

Much of the reaction to that nearly three-hour exchange between a snide, cantankerous (often misinformed and misinforming) Carlson and an impressively polite, knowledgeable and well-spoken Huckabee was about the ambassador’s honest admission that he believed that Hashem’s promise of Eretz Yisrael to Avraham Avinu included a much larger swath of land than present-day Israel.

Challenged by Mr. Carlson about whether that entire land belongs to the Jews today, Ambassador Huckabee responded, “It would be fine if they took it all…” sending media muckrakers running to their keyboards and Arab countries to their ready-to-rattle sabers. But they all seem to have not listened much further to when Mr. Huckabee made clear that Israel has no designs on Jordan, Syria or Iraq. The rest of his sentence was “but I don’t think that’s what we’re talking about here today.

“They don’t want to take it over,” he continued. “They’re not asking to take it over.”

But the more noteworthy parts of the interview were those in which Carlson touted his own Christian identity. He even questioned the Christian credentials of his interviewee. At one point, after lamenting the fact that the IDF had bombed churches and a Christian hospital in Gaza (places that held caches of Hamas’ weapons, as Mr. Huckabee patiently explained), Mr. Carlson said: “I would expect you to side with the Christians over the secular government of Israel.”

Mr. Carlson also claimed that the Christian population in Israel is dwindling and pales by comparison with the population in Qatar. He was informed by Mr. Huckabee that the first contention was false: the Christian population of Israel has grown to approximately 184,000, and the country hosts hundreds of churches. And, regarding the second claim, that Christians in Qatar are overwhelmingly migrant workers confined to a restricted church compound.

We must hope that “influencers” like Carlson and Prejean Boller fail to influence. But it’s sobering and concerning that the former averages a million viewers per podcast and that the latter, in the wake of her commission conniption, gained 30,000 followers on social media.
