Christians United for Israel, CUFI, on Tuesday said it distributed an action alert to its membership in opposition to the Presbyterian Church USA’s recent vote to divest from three companies that do business with Israel, and, within 24 hours the alert generated more than 26,000 responses in support.

David Brog, executive director of CUFI, the largest pro-Israel organization in the U.S. with 1.6 million standing members, said, “The Presbyterian Church USA has demonstrated its moral cowardice to the world.”

“Happily, this small and shrinking denomination does not speak for America’s Christians or Americans in general,” Borg said. “We refuse to jump on this anti-Israel bandwagon. We refuse to ignore the real human suffering in the Middle East – from Syria to Iraq to Iran. And we refuse to blame Israel and Israel alone for its conflict with its Arab neighbors.”

CUFI said the action alert respondents sent emails to the office of Israeli Prime Minister Benjamin Netanyahu “to let Israelis know that in spite of PCUSA’s actions, American Christians stand with the Jewish state.”

CUFI will be hosting a summit in Washington, D.C., from July 21 to 23, where 6,000 members are expected to visit most of the U.S. Representatives and Senators to press the U.S. to continue its support of Israel.

On Friday, PC USA leaders voted 310-303 to approve a motion at the church’s biennial general assembly in Detroit to divest from Caterpillar, Hewlett-Packard and Motorola because the companies do business with Israel.

The vote was publicly supported by David Duke, the former Ku Klux Klan Grand Wizard and frequently unsuccessful U.S. political candidate, drawing ridicule of the organization which said the vote was not based on anti-Semitism. On his website, Duke said: “Bravo to the Presbyterian Church for standing up to Jewish racism and supremacism!”
