The fact that in the fullness of time the Eternal Word took on the condition of a creature gives a unique cosmic value to the event which took place in Bethlehem two thousand years ago. Thanks to the Word, the world of creatures appears as a “cosmos,” an ordered universe. And it is the same Word who, by taking flesh, renews the cosmic order of creation. The Letter to the Ephesians speaks of the purpose which God had set forth in Christ, “as a plan for the fullness of time, to unite all things in him, things in heaven and things on earth.” (1:9-10)
