Anselm ( Cur Deus Homo , 1.18) offers this lovely description of the consummation of all things.
Creation consists on the one hand of the blessed city that is being built and brought to consummation. Physical creation is also destined to be renewed into something better ( in melius renovandam nec hoc futurum esse ). The latter immediately follows the former, because the higher ( maior ) nature has to be perfected before the lesser ( minor ).
The result ill be a co-rejoicing ( congaudendo ) of rational beings and lesser creation, each in its own way “joining in eternal rejoicing in its Creator and in itself and in their mutual relations to one another, upon this final fulfillment of itself, so glorious and so amazing.”
