It is worth noticing how far from anthropocentric is this vision of worship. Humanity is radically displaced from the centre of things where human beings naturally tend to place themselves. At its heart and in its eschatological goal the creation is theocentric, orientated in worship towards its Creator. But even among the worshippers human beings are not pre-eminent. The four living creatures who lead the worship of the whole creation are not portrayed as anthropomorphic beings, as angelic beings often are. Only the third has a face resembling a human face. The others resemble a lion, an ox and an eagle, and with their six wings and myriad eyes all have a heavenly superiority to all earthly creatures (4:6-8). Their representative function is to worship on behalf of all creatures, and therefore it is fulfilled when the circle of worship expands to include not only humans, but 'every creature in heaven and on earth and under the earth and in the sea' (5:13).
