The Archdiocese of New York is providing children from several hundred schools with coloring and comic books that warn about sex predators “ in an age-appropriate and sensitive way,” a spokesman for the archdiocese said.

The coloring book titled “Being Friends, Being Safe, Being Catholic” features a cartoon female guardian angel that advises children to not go into a room alone with an adult, to not keep secrets from their parents and to not meet anyone from an Internet chat room.

The little ones are likewise advised to allow only “certain people” like a doctor or parent to see “where your bathing suit would be.”

On one page, the smiling angel says: “If a child and an adult happen to be alone, someone should know where they are, and the door should be open or have a big window in it.”

The image shows an altar boy removing his church smock, in what appears to be a church sacristy, as a man who seems to be a priest looks at him through the wide open door and smiles. The words “shouldn’t,” “open” and “know” are written in bold type.

Priests are never named outright as potential aggressors but the move has been deemed bold by some nonetheless.

Joseph Zwilling, a spokesman for the archdiocese, said this is the first effort of this kind to be produced by church officials. David Clohessy, national director of the Survivors Network of those Abused by Priests, said he was unaware of any previous similar effort.

Clohessy however added that the coloring book should have been more clear in expressing the idea that all adults, even those trusted, even, priests, are potential abusers.

“There continues to be a bit of an overemphasis on stranger danger,” Clohessy said, as quoted by the Associated Press. “I think it would be most effective if it would say, 'Not only strangers molest kids. Even adults you like and your parents respect, teachers, doctors, priests, can hurt kids.'”

Zwilling argues that the vast majority of priests are “good and holy men,” reports the AP, and that it would have been inappropriate to place emphasis on priests as potential abusers. “You don't want to frighten children,” he said. “You also don't want to stigmatize any group.”

“It's to help young people to know situations they should not get into,” Zwilling said. “How to be safe — but to try to do it in an age-appropriate and sensitive way.”

The archdiocese has also produced a comic book for children over the age of 10.

Zwilling said the books have been distributed to about 300 schools and 400 religious education programs.
