A prominent Christian group launched a salvo at anti-immigration advocates Thursday, alleging that many of those who oppose immigration reform “believe strongly in population control.”

The group pulled no punches, referencing an article that alleges links between abortion, eugenics and opposition to immigration reform.

A representative of the National Association of Evangelicals, a Christian group representing more than 45,000 churches from 40 denominations, wrote in an email to supporters: “Some of the most prominent groups organizing to oppose reforms would like to dramatically reduce not just unlawful migration, but all migration to the U.S., because they believe strongly in population control.”

The email links to a “Human Life Review” article, which alleges that anti-immigration groups like FAIR, CIS and NumbersUSA have roots in movements supportive of eugenics and abortion.

NAE, which is part of Evangelical Immigration Table umbrella group, also encourages its members to pray for anti-immigration advocates to ask “God to help them-and each of us-to see immigrants as He does, as people made in His image.”

“It’s quite concerning. We’re not saying that everyone who opposes immigration supports abortion,” Galen Carey, VP of Government Relations for the group told the Washington Examiner. “The bigger messaging that we’re trying to get out of this is that as we pray for reform, we also praying for those who have different ideas for us.”

On July 24, evangelical Christians will gather in Washington, D.C. to pray for immigration reform and meet with Congressional leaders.

“This is a call to prayer, and we hope that people will pray for anyone engaging in the debate for immigration reform,” Carey said. “We’re for sensible reform that respects the rule of law that protects our borders.”
