Boston Catholics in a tizzy over sketchy ad

A sexy magazine ad showing a group of nuns sketching a buff, naked man has Boston's Catholic community in a tizzy.

"It's offensive to an entire community of religious, who give their lives to the good works of the church," says Terry Donilon, of the Boston Archdiocese, to WHDH-TV.

Officials from Equinox Fitness, with only one Boston location in the Back Bay area, defend the provocative campaign that appears in the latest issue of Boston Magazine.

"The ads capture the energy and artistry of the well-conditioned body in a thought provoking fashion, blending fantasy and impact," Equinox says in a prepared statement.

Too racy for Boston's Puritanical views on sex and the human body? Perhaps. Smart advertising campaign that pushes all of the right buttons? Absolutely.
