The only information I was able to found was an interview on Vox. I'm not sure what moment he's talking about for the "crucifixion of Xavier" scene, but Brent Anderson talks about that response:

"I felt the same way about the "crucifixion of Xavier" scene. I was so gratified and validated by Pat Robertson on his 700 Club televangelist TV show holding up that scene on camera and condemning it for being "blasphemous." Robertson was completely taken by the imagery, and didn't at all understand the context of the scene."
