II. The Name, Titles, and Symbols of the Holy Spirit

695
Anointing.
the symbolism of anointing with oil also signifies the Holy Spirit,³⁰
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.³¹ 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.”³² 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.³³
The Spirit filled Christ and the power of the Spirit went out from him in his
acts of healing and of saving.³⁴ Finally, it was the Spirit who raised
Jesus from the dead.³⁵ 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”:³⁶ “the whole Christ,” in St.
Augustine’s expression.
