From an interview with Grant:

"Chris, Tim and James definitely consider themselves Christian. Daniel doesn’t really consider himself “Christian.” Term-wise, he still believes in God and things. And I honestly can’t tell you what I call myself. And Spencer’s on the same boat I am. On a personal level, this is just me speaking for myself, Grant, I have lately found a big turnoff to Christians as far as an ignorance factor and a judgmental factor [goes]."
