Okay, LOL! I see the issue, there. Uh, the article says there are comedy skits in the church, it doesn't say they're used as a form of worship; more probably they're bieng used as a means of illustrating a scriptural principle related to the message being preached on any given Sunday.
Sin? LOL! No.
It's just a different means of presenting an illustration; a more attention-holding alternative to the traditional man-behind-the-wooden-box-talking-and-gesticulating method.
Or even more likely, they are merely entertainment for the same kind of shallow itching-ears types who'd agree that "church is boring."
