As in chs. 1–3, the church is pictured in angelic guise to remind its members that already a dimension of their existence is heavenly, that their real home is not with the unbelieving “earth-dwellers,” and that they have heavenly help and protection in their struggle to obtain their reward and not be conformed to their pagan environment. One of the purposes of the church meeting on earth in its weekly gatherings (as in 1:3, 9) is to be reminded of its heavenly existence and identity by modeling its worship and liturgy on the angels’ and the heavenly church’s worship of the exalted lamb, as vividly portrayed in chs. 4–5. This is why scenes of heavenly liturgy are woven throughout the Apocalypse (see further on 1:20).
