Paul Griffiths on the liturgy anticipating heaven

"[A]ttending to the liturgy is the closest we can get, here below, to attending to heaven. In examining it, we approach as close as we can get to examining the life of the saints in heaven as it is once they are resurrected and enjoying both sensory and nonsensory modes of knowing and seeing the LORD. This is because most of the elements of the life of the world to come are present in nuce in the worshiping assembly: the ascended LORD is present in the flesh; the gathered people is an assembly of those who know and love him as he is, at least to some degree; and the fabric of the event is woven from the threads of love exchanged—love given preveniently by the LORD, whose creature the church is, and love given responsively by the people, who have collectively and individually been brought into being by the LORD. The leitmotif of the words and actions of the liturgical gathering is adoration. All this is also true of the gathering of the resurrected saints around the LORD's ascended flesh in heaven."
