The thing about Word Broadcasting is that while they mostly are a Christian programmer, their TV station (WBNA) isn't just all-on Christianity 24/7. In fact, almost all of 21 and their sub-channels is secular stuff, and they even have some stuff on that channel that is decisively anti-Christian (that questionably tasteful Deadbeats show they do in the Jefferson County court stands out above the rest). In fact, looking at WBNA and all of their sub-channels, the main one (21.1) airs almost all secular stuff with an exception of religious programming later in the evening, and four others air nothing but secular stuff. Only one of their sub-channels (21.3) is religious programming all day, every day.
None of that means they'll do the same thing with their radio stations they're running, of course, but I could see them playing around with nonsecular stuff a little bit more than some other religious broadcasters would. Much like Salem does, with their conservative talk station. Of course that may just mean they'll leave the conservative talk on 970.
