I was employed by Franciscan Communications back in the late 1980s. They were a Catholic Organization that made high production movies and books about Catholic life.
Some of their movies used people like Martin Sheen, Joseph Camponella (sp?), director Alan Davia, and even Jack Nicholson in his early days.
I worked on a Time/Life style set of books for Catholics and most of the photography was not "religious" per se. It was mostly about the interaction of families and people in daily life. There were of course pictures of religious events but the thrust of the work was pretty much every day people living their lives. I made about 10,000 photographs for them and they used them in their books and video covers.
It wasn't high art, just everyday life.
