Originally, I was offended by this song. I didn't listen to it for years. I believed it was yet another trending shot at Christianity. As I listened further my perception changed. I believe the song is more anti-establishmentarianism by addressing endless profitable war, control, and deception.
Although, other interpretations are the song is about drug addiction, and indeed possibly a song about Christianity. Maybe all three? I prefer my interpretation as relevant to modern times. The genius is the possibility for all interpretations and the choice of interpretation.
