Church size matters. Well, not really, but it can have an interesting affect on the spiritual beliefs of a congregation.
Despite the persistent perception that mega-churches somehow water down the faith in order to attract people, research shows that members of larger churches consistently have more orthodox beliefs. A Barna survey released in October shows significant differences in belief between churches of fewer than 100 people and churches of more than 1,000 people.
On every single belief indicator–questions ranging from the accuracy of the Bible, to the responsibility for personal evangelism, to the reality of Satan–people attending larger churches were more likely to give the orthodox response. The differences ranged from as low as 9% to as high as 25%.
When the research pushed beyond belief to practice, large church attendees were 17% more likely to be active across seven different behavioral indicators (attending church, reading the Bible volunteering at church, etc.).
So can we finally put to rest the idea that mega-churches are somehow weak on theology?
Size of the Numbers
On a less related note, the study found that 41% of adults attend a church of fewer than 100 people. If you push the congregation size to 200 you account for 64% of church attendees. Only 9% attend a church with 1,000 or more people.
