VIA Last week, the conservative broadcaster Glenn Beck called on Christians to leave their churches if they hear preaching about social or economic justice, saying they were code words for Communism and Nazism.

“What he has said attacks the very heart of our Christian faith, and Christians should no longer watch his show,” Mr. Wallis wrote on his blog, God’s Politics. “His show should now be in the same category as Howard Stern.”

In attacking churches that espouse social justice, Mr. Beck is taking on most mainline Protestant, Roman Catholic, black and Hispanic congregations in the country — not to mention plenty of evangelical churches and even his own, the Church of Jesus Christ of Latter-day Saints.
