’The Revelation of Jesus Christ.’ Those are the first words of John's message to the persecuted Churches. He wished to give them a teaching that would enlighten and comfort them. Although not new, it would be more developed on the person and role of Jesus, ‘the faithful witness, Firstborn among the dead, Prince of the kings of the earth’ (1, 5). To give them confidence in the midst of trials, he would make manifest the active presence and entire mastery in temporal history of the risen Lord.
