You may have known that the ROBERTSONS from "Duck Dynasty"are Christians, but did you know how SERIOUS about it they are?

Various family members . . . including WILLIE and PHIL ROBERTSON . . . frequently preach to the congregation at White's Ferry Road Church of Christ in West Monroe, Louisiana.  The family has been attending the church for 30 years.

In fact, last weekend there was something called "Duck Commander Sunday," which is an annual tradition where the entire Robertson family preaches, in FULL CAMO.  Apparently, this has been a yearly thing since even BEFORE the show.
