Books with plots similar to the video game: Cult of the Lamb?

Here’s a basic summary of the game:

”In a land of false prophets, The Lamb, supposedly the last of their kind, is brought before The Four Bishops of the Old Faith, and is sacrificed before them. Upon dying, The Lamb is brought before "The One Who Waits", a strange deity who is imprisoned in chains. The One Who Waits tasks The Lamb with starting a cult in its name, gives The Lamb a demonic crown, then resurrects it.”
