A study of Protestant churches in Canada has found that growing churches tend to be more orthodox, while shrinking ones are theologically liberal.

Terry Mattingly, author of the Get Religion blog, covered the findings of the study, which appeared in the peer-reviewed journal, Review of Religion Research.

The researchers, David Millard Haskell, Kevin N Flatt and Stephanie Burgoyne, looked at 22 mainline Protestant churches in Canada. Nine of the churches were growing in attendance, while 13 were declining. The researchers found that when other factors were controlled for, ”the theological conservatism of both attendees and clergy emerged as important factors in predicting church growth.”
