“The Magi see a star in the East and they know that a King has been born in Judea. Who is that King, so small and so mighty, not yet speaking on earth and already issuing commands in heaven?
In truth He did this for us, in His desire that we might learn about Him from the sacred Scriptures, and for the Magi, that they might believe in Him from His prophecies even though He had given them so bright a sign in the heavens and had revealed to their hearts that He was born in Judea.
For, in seeking the place where He whom they desired to see and to adore was born, they had to contact the leaders of the Jews, so that these unfaithful men, wittingly deceptive but unwittingly truthful, might give evidence to the faithful about the grace of faith, evidence drawn from holy Scripture which they carried on their lips but not in their hearts.
How wonderful it would have been if these leaders of the Jews, when they had heard from the Magi that under the guidance of the star they had come desiring to adore Him, had associated themselves with the searchers for Christ, had led them to Bethlehem, which they had pointed out from the sacred books, and had seen, understood, and adored Him along with them?
Instead, after directing others to the fountain of life, they preferred to die of thirst.
They became, as it were, milestones to these strangers; they indicated the path to the travelers but they remained motionless and immovable.”
