Raine, Eliot, Murder in the Cathedral

Raine comments on Murder in the Cathedral:

Eliot's coinage, 'Unreal city', [in The Waste Land] owes a great deal to Buddhist ideas of maya or illusion. Later it is assimilated to the Christian idea of this fleeting world. In Murder in the Cathedral, the chorus refers to Hebrews 13:14: 'for here we have no continuining city, but we seek one to come.' Or, in Eliot's play: 'Here is no continuing city, here is no abiding stay'. Religions have a way of slighting the temporal. p. 82

Is this what really happens in the play, and in Christian thought too? Is the temporal 'slighted'? The pressing urgency of the present is certainly reduced by Christian eschatology. But, on the other hand, you could easily argue that the temporal is given renewed significance: as Paul says, in light of the resurrection 'your labour in the Lord is not in vain'.
