Television is largely a godless place, some would say, but not this month. Programs with biblical or other religious themes are sprouting up, some in places where you might not expect them. If nothing else, costumers who traffic in robes and sandals are doing a booming business.

The reason for the fervor isn’t hard to fathom: Not only is Easter coming, but so also is “A.D.: The Bible Continues,” the latest offering from Roma Downey and Mark Burnett. They’re the couple behind the History channel mini-series “The Bible,” whose immense popularity caught the television world by surprise in 2013.

“A.D.,” which is scheduled to begin on April 5 on NBC and concerns the time after the Crucifixion, will no doubt make a ratings splash, too, especially with believers who like their Christianity loud and full of suffering. “This is ‘Game of Thrones’ meets the Bible,” Mr. Burnett says in a trailer.

The same audience-grabbing calculation behind that statement is why you can find religion-themed fare in the next few weeks on CNN, PBS, the Smithsonian Channel, even the Weather Channel. If “A.D.” is going to be another “Bible”-size hit, lots of TV executives want a seat on the bandwagon.
