The Robertson family, stars of A&E's mega-hit reality sitcom Duck Dynasty, are devout Christians who often preach at their local church in W. Monroe, La.
A ministry assistant at White's Ferry Road Church of Christ says that family patriarch Phil Robertson and his family have been active there for 30 years.
Phil regularly gives passionate sermons, and last weekend, the entire family joined in on Duck Commander Sunday, which is an actual annual tradition.
Duck Commander Sunday existed long before the A&E TV show that made the family famous, and despite the abundance of camo, it's not some stunt.
These guys are sincere in their faith. Check out the video above.
