Some people erroneously believed Brother William Branham was God.  Brother Branham was not God, he was a man who was a sinner saved by God's grace.

In the sermon "Believing A Man Is God," Brother Pearry Green clarifies this. (This sermon is part of the Clarification series that is available from Tucson Tabernacle.)

Brother Branham rebuked this spirit that believes him to be God. (This sermon has been called by many names, including “Bruised Serpent,” “Who Is William Branham,” and is now titled “Revelation, Chapter 5, No.1.”)
