Black Sabbath was a Christian Band. I always sensed this, since I actually listened to the lyrics. Read “After Forever”

5. Black Sabbath

Black Sabbath were frequently accused of promoting the occult and Satanism, which is pretty ironic given that many of their songs were clearly quite Christian, and Ozzy Osbourne was singing about fearing the devil and a vengeful God.

“Black Sabbath”

Big black shape with eyes of fire / Telling people their desire / Satan’s sitting there, he’s smiling / Watches those flames get higher and higher / Oh no, no, please God help me!

“War Pigs”

Now in darkness world stops turning / Ashes where the bodies burning / No more war pigs have the power / Hand of God has struck the hour / Day of judgment, God is calling / On their knees the war pig’s crawling / Begging mercy for their sins /
Satan laughing spreads his wings / Oh Lord, yeah!

“After Forever”

Have you ever thought about your soul – can it be saved? / Or perhaps you think that when you’re dead you just stay in your grave / Is God just a thought within your head or is He a part of you? / Is Christ just a name that you read in a book when you were at school? / When you think about death do you lose your breath or do you keep your cool? / Would you like to see the Pope on the end of a rope – do you think he’s a fool? / Well, I have seen the truth / Yes, I have seen the light and I’ve changed my ways / And I’ll be prepared when you’re lonely and scared at the end of your days / Could it be you’re afraid of what your friends might say / If they knew you believe in God above / They should realize before they criticize / That God is the only way to love.
