The distinction between Christ and the angels which John establishes in chapter 5 with regard to the work of establishing God’s reign is therefore strictly parallel to the distinction we have observed John using with regard to the giving of revelation. Just as the angels are only fellow-servants with the Christian prophets in the communication of revelation and may not be worshipped (19:10; 22:8-9), so the angels who implement the divine purpose in history are only fellow-servants with the prophets and martyrs who bear the witness of Jesus in the world. In both cases, however, Christ, although He receives the revelation from God (1:1) and the scroll from God (5:7), is not classed with the servants who may not be worshipped but with God to whom worship is due.
