According to union-backed critics of Wal-Mart Stores, not at the world's largest retailer. WakeUpWalMart.com unveiled a religious-themed campaign Thursday asking shoppers whether God wants them to buy things from the Bentonville, Ark.-based company.

The group, funded by the United Food and Commercial Workers International Union, launched a TV ad and released a letter signed by 65 clergy members and religious figures. The group says Wal-Mart's policy on wages, health benefits and other issues harms families and communities.

Wal-Mart accused the group of using union dues to exploit religion and said it would give nearly $200 million in cash contributions to charities this year.

The 30-second TV spot, starting today in Alabama, Arkansas, Georgia, Kentucky, Oklahoma and Texas, is part of the latest seasonal-themed campaign against Wal-Mart. The TV ad starts with a picture of a Bible-like tome and a narrator who says, "Our faith teaches us 'Do unto others as you would have them do unto you.'

"If these are our values, then ask yourself: Should people of faith shop at Wal-Mart this holiday season?"

Wal-Mart spokeswoman Sarah Clark criticized the ad.

"Surely Americans are deeply offended that the union leadership would use religion as just another tactic in a negative attack campaign against a company that donates more money to good works than any other company in America," she said.

The letter from clergy members took a line similar to the ad's.

"Jesus would not embrace Wal-Mart's values of greed and profits at any cost, particularly when children suffer as a result of those misguided values," the letter said.

Clark said the clergy had been misled.

"We share their compassion for people just like we continue to provide jobs to those who want a better life. We save the average American family $2,300 a year per household," she said.
