An ad for a new upscale Boston fitness center featuring three nuns painting a naked man is getting some flack from religious leaders there, MyFoxBoston reported.

"These are people that work in hospitals, our homeless shelters and in our food pantries," Terry Donilon, a spokesman for the Boston Archdiocese, told the station. "It shows a lack of respect for them."

The two-page ad is the first thing readers see when they open up the latest issue of Boston Magazine.

The ad, created by an unnamed Minnesota agency, features three nuns -- one wearing a garter -- painting the chiseled man while a fourth nun watches from behind a gate.

The gym, Equinox Fitness, issued the following statement: "The ads capture the energy and artistry of the well-conditioned body in a thought-provoking fashion, blending fantasy and impact."

An assistant for Boston Magazine president Daniel Scully declined to comment on the ad, telling FOXNews.com it was Equinox Fitness' creation and the fitness club had already issued a statement.

"There will be no further comment," the assistant said.

Despite the racy ad, there have been no reported claims to have it pulled, MyFoxBoston reported.
