"David himself calls him 'lord' "

"...so how is he his son?"

-- Mk12:35-37

Many Jews and even certain Gentiles who shared their hope recognized in Jesus the fundamental attributes of the messianic "Son of David", promised by God to Israel. Jesus accepted his rightful title of Messiah, though with some reserve because it was understood by some of his contemporaries in too human a sense, as essentially political.

-- CCC 439

As Jesus was teaching in the temple area he said,
"How do the scribes claim that the Christ is the son of David?
David himself, inspired by the Holy Spirit, said:

The Lord said to my lord,
'Sit at my right hand
until I place your enemies under your feet.'

David himself calls him 'lord';
so how is he his son?"
The great crowd heard this with delight.

Anointing. The symbolism of anointing with oil also signifies the Holy Spirit, to the point of becoming a synonym for the Holy Spirit. In Christian initiation, anointing is the sacramental sign of Confirmation, called "chrismation" in the Churches of the East. Its full force can be grasped only in relation to the primary anointing accomplished by the Holy Spirit, that of Jesus. Christ (in Hebrew "messiah") means the one "anointed" by God's Spirit. There were several anointed ones of the Lord in the Old Covenant, pre-eminently King David. But Jesus is God's Anointed in a unique way: the humanity the Son assumed was entirely anointed by the Holy Spirit. The Holy Spirit established him as "Christ." The Virgin Mary conceived Christ by the Holy Spirit who, through the angel, proclaimed him the Christ at his birth, and prompted Simeon to come to the temple to see the Christ of the Lord. The Spirit filled Christ and the power of the Spirit went out from him in his acts of healing and of saving. Finally, it was the Spirit who raised Jesus from the dead. Now, fully established as "Christ" in his humanity victorious over death, Jesus pours out the Holy Spirit abundantly until "the saints" constitute - in their union with the humanity of the Son of God - that perfect man "to the measure of the stature of the fullness of Christ": "the whole Christ," in St. Augustine's expression.

Saint Peter, martyred on that spot, and Saint Paul likely set eyes upon this monument as they witnessed the martyrdom of many brothers and sisters in the Faith. Photo by author.)
