It turns out Campbell has a whose beliefs are nothing like hers. But because he grew up in a fundamentalist family, he’s well aware of Christian culture and his mom’s place in it. Caleb Campbell even co-hosts a podcast called “Bible Beaters” where he (the of a “famous prophet and evangelist&rdquo and Kyle Vestner (who “hasn’t even cracked the cover” of the Bible) go through biblical stories and riff on them. After his mom’s newfound virality this week, Caleb discussed the video and offered a rather interesting revelation:

KYLE: Does Stacey ever do this [around you]?

CALEB: No, that’s the thing! She never just drives the car and breaks into prophecy. Never happened once while she was making dinner. Only in front of thousands of people does this ever happen.
