What is the book of Revelation about?

The book announces itself as “the Revelation of Jesus Christ, which God gave him to show to his bondservants the things which must happen soon. He sent it and made it known by his angel to his bondservant” (Rev 1:1).

Revelation contains many mystical representations of the spiritual state of the Church and speaks of the destinies of Christians and of the whole world, in symbols whose right interpretation requires the mind of the Church, as the study that follows explains.
