A JD Wetherspoon Sunday drinks promotion, which uses images of beer bottles with halos and wings, has received heavy criticism from church leaders.
The promotion was launched into all of the chain's pubs in Scotland this month as a tongue-in-cheek way of highlighting cheap prices.
But ministers at the Free Church of Scotland have attacked it for using Christian symbols to sell drinks - which is blasphemy, according to the church.
David Meredith, spokesman for the Free Church of Scotland, said: "I think this is blasphemy. The chain has taken an incredibly holy concept and treated it with utter contempt. I would ask them to seriously consider the offence that this might cause to some people.
"It is also extremely inconsiderate considering Scotland has such a serious alcoholism problem."
But Wetherspoon spokesman Eddie Gershon said the company had no intention of causing offence to the church.
"The campaign was established to simply put the message across that we were serving cheap drinks on a Sunday in a very tongue-in-cheek way," Mr Gershon said.
"The actual promotion has gone well and we've had no complaints from customers who are just interested in the fact that prices are cheaper than usual.
"We have no plans to withdraw the campaign, but the criticism has been received and we will take it on board and will do our best not to offend people in the future."
