The document is a message from God to the angel of the church in Pergamos. It commends them for holding fast to faith in God even where Satan dwells. However, it criticizes them for tolerating those who hold doctrines like Balaam, who led Israelites into idolatry. God warns that he will come quickly and fight against them if they do not repent from such teachings. He promises the one who overcomes a white stone with a new secret name.
