On the eve of her 100th birthday Saturday, Ruth Salton told her daughter she was going one way or another to Friday night Shabbat services at Congregation Beth Israel, just days after a gunman voicing antisemitic conspiracy theories held four worshipers hostage for 10 hours at the Fort Worth-area synagogue.

“I want to support my people,” said Salton, a Holocaust survivor. She said she told her daughter “if she doesn’t take me, I’ll go by myself, because I feel I belong there. I am Jewish, and this is my faith, and I am supporting it.” She’s far from alone.

At synagogues around the U.S., Jewish leaders marked the first Sabbath since last weekend’s hostage-taking at Beth Israel in Colleyville, Texas, with a show of defiance against it and other acts of antisemitism. Many called for a strong turnout to show unity among the faithful, and rabbis, public officials and others spoke out during the Friday night and Saturday services against acts of violence, hatred and intimidation aimed at Jews.

At Beth Israel’s service Saturday, Rabbi Charlie Cytron-Walker and the three other people who were taken hostage last weekend stood in front of the congregation, linking arms as they sang the ritual blessings before and after the weekly reading of the Torah.

And at Friday night services marking the start of the Sabbath, or Shabbat, Cytron-Walker said: “The words Shabbat Shalom, to be able to offer that to each and every one of you, those words have never, never felt so good. While we have a lot of processing to do, God willing, the worst is over ... and we can have a Shabbat of peace.”

Viewers of Beth Israel’s Facebook Live broadcast of its Saturday service sent greetings from Jerusalem, Florida, North Carolina and elsewhere.

During the standoff, the hostage-taker forced Cytron-Walker to call Rabbi Angela Buchdahl of Central Synagogue in New York City in a bid to win Siddiqui’s release, according to authorities. She then reported the call to law enforcement.

Christian and Muslim clergy joined in Central Synagogue’s Friday service in a show of solidarity, linking arms and swaying with Buchdahl and Mayor Eric Adams as the congregation sang a song of thanksgiving.

“Once again, we are facing the terror of all of the things that are happening in our city and country,” Adams said, recalling how New Yorkers rebounded after the Sept. 11 attacks. “In New York, this is our obligation: to get up again to make sure that people know that we are resilient, we’re loving, we’re kind.”

In Pittsburgh, Rabbi Jeffrey Myers of the Tree of Life Congregation struck a similarly defiant tone. On Oct. 27, 2018, a gunman killed 11 worshipers from three congregations meeting at Tree of Life’s synagogue in what authorities said was the deadliest antisemitic hate crime in U.S. history.

“I, for one, did not survive Oct. 27 to become a professional victim for the rest of my life,” Myers said, adding that the response to antisemites is to engage more deeply in Jewish practice.

“We cannot let terrorists determine our Jewishness,” he said at Friday night services. “We did not let the alleged shooter at the Tree of Life do that, and we will not let the hostage taker in Texas do that.”

Authorities say Malik Faisal Akram, a British national, took the four people who were at Congregation Beth Israel last Saturday hostage.

He was demanding the release of Aafia Siddiqui, a Pakistani neuroscientist convicted of trying to kill U.S. troops in Afghanistan and who is serving a lengthy sentence in a prison in Fort Worth, which is 15 miles southwest of Colleyville.

The hostages said Akram cited antisemitic stereotypes, believing that Jews could wield power over President Joe Biden to have Siddiqui released.

The siege ended after the last hostage ran out of the synagogue and an FBI SWAT team rushed in. Akram was killed by multiple gunshot wounds.
