"We often are compared to our male counterparts and expected to be more complacent and not challenge the norm," Deer Lake United Church Reverend Tracy Fairfield — who is featured along with her family in February — told CBC Radio The Early Edition's Rick Cluff.
The calendar was launched by Rev. Trisha Elliott — a United Church minister in Ottawa — after she had her photo taken.
"The photographer said, 'Oh, don't tilt your head like that. You look a little too much like Jennifer Aniston. You've got to look like a minister,'" said Fairfield.
"You don't want to sexualize or dramatize the image of a minister. You've got a stereotypical role that people think we should have."
Elliott connected with female ministers like Fairfield, and they came up with the idea for a calendar.
Barely a month into the new year, the second printing of the calendar is already sold out.
"It's just so popular, we weren't expecting such a huge sell out. It's been truly amazing."
Fairfield isn't sure if a 2016 calendar is in the works.
"It's a provocative idea. I don't know if it's one to be duplicated."
