I heard this song was a reaction to preachers and crap accusing of them of being satanic when their previous songs really had pro-christian theme hidden at their core, so this is whoever wrote the lyrics finally snapping back out against them. It's not so much anti-christian as anti-preacher. Either that or Black Sabbath has multiple lyricists with conflicting views or they changed views between albums.
