Canadian researchers have statistically demonstrated the "secret" behind growth of churches - theology. Many other studies have linked church growth to members and pastor age groups, society and family conditions among many any suspect factors. But a five-year study carried out by Wilfrid Laurier University and Redeemer University College in Ontario found that churches following conservative Christian beliefs were more likely to grow than churches teaching liberal doctrines.
The researchers surveyed over 2,200 members of Presbyterian, Anglican, Lutheran and United churches in Ontario, and attended 22 churches. About 9 of them were the congregations which had witnessed 2% growth over the last decade, while the other 13 had declined by the same rate.
The pastors and the members were given a set of 40 questions on their beliefs and personal faith practice.
