and were amazed at the gracious words that came from his mouth.
They also asked, “Is this not the son of Joseph?”
He said to them, “Surely you will quote me this proverb,
‘Physician, cure yourself,’ and say, ‘Do here in your native place
the things that we heard were done in Capernaum.’”
And he said,
“Amen, I say to you, no prophet is accepted in his own native place."
-- Lk 4:16-30
The word "Christ" comes from the Greek translation of the Hebrew Messiah, which means "anointed". It became the name proper to Jesus only because he accomplished perfectly the divine mission that "Christ" signifies. In effect, in Israel those consecrated to God for a mission that he gave were anointed in his name. This was the case for kings, for priests and, in rare instances, for prophets. This had to be the case all the more so for the Messiah whom God would send to inaugurate his kingdom definitively. It was necessary that the Messiah be anointed by the Spirit of the Lord at once as king and priest, and also as prophet. Jesus fulfilled the messianic hope of Israel in his threefold office of priest, prophet and king.
