The Reign of Christ is a celebration of looking forward to the end of time when all things will come to their fruition in God, when God's will for justice and peace on earth will be fulfilled. Celebrating this vision of the final fulfilment helps us to re-order our priorities for living in the moment.
This is the quote by Jürgen Moltmann (from Theology of Hope) that I shared in the sermon on November 26:
That is why faith, wherever it develops into hope, causes not rest but unrest, not patience but impatience. It does not calm the unquiet heart, but is itself this unquiety heart in humanity. Those who hope in Christ can no longer put up with reality as it is, but begin to suffer under it, to contradict it. Peace with God means conflict with the world, for the goad of the promised future stabs inexorably into the flesh of every untilled present.
Amen - and may we carry this spirit with us into the new year that begins on Advent 1.
