First in verse 5 he says we want to make sure the Word of God is not blasphemed.
Now it seems that Christianity is something to be lampooned, ridiculed, and freely blasphemed.
They blasphemed the Virgin, allegorizing her as the upper Jerusalem in which the Lord came in and went out, and denying that he was really made flesh of her.
All of these worshipped images of the gods and of the emperor, and blasphemed Christ.
