10. And I took the book from the hand of the angel, and ate it up: and it was in my mouth sweet as honey: and when I had eaten it, my belly was bitter.
11. And he said to me: Thou must prophecy again to many nations, and peoples, and tongues, and kings.
8-10. Eating the book symbolizes an intimate union with the Holy Ghost by which the mind of the Apostle is illuminated with the spirit of prophecy. St. John finds the book sweet to the taste because it announces mercy to the elect and the final triumph of the Church. It is bitter in so far as it predicts dire persecution for the Church and terrible punishment for the wicked.
11. The angel commands St. John to announce to all the prophecy communicated to him concerning the reign of Antichrist, the subsequent triumph of the Church, and the final persecution under Gog and Magog.
