O King [of the nations] whom all the peoples desire, you are the cornerstone which makes all one. 

O come and save man whom you made from clay.

Isaiah (once again!) writes: “He shall judge between the nations, and shall arbitrate for many peoples; they shall beat their swords into ploughshares, and their spears into pruning hooks; nation shall not lift up sword against nation, neither shall they learn war any more” (2,4). In this passage and elsewhere, the prophet is looking forward to the Messianic age, which will be a time of justice and peace. 

John writes in Revelation, “Jesus Christ [is] the faithful witness, the first-born of the dead, and the ruler of the kings of the earth…” (1,5).   “Pilate asked him [Jesus], ‘So you are a king?’ Jesus answered, ‘You say that I am a king. For this I was born, and for this I came into the world, to testify to the truth. Everyone who belongs to the truth listens to my voice’” (Jn. 18,37). The ‘kingship’ of Christ is emphasised in the calendar of the Catholic Church, which celebrates the feast of Christ the King on the last Sunday before Advent.
