Jesus was anointed. Both “Christ” (in the New Testament) and “Messiah” (in the Old Testament) mean “anointed.”
Anointing was done in the Old Testament using oil that was poured over the head, and not just a little dab. “It is like the precious oil on the head, running down on the beard, on the beard of Aaron, running down on the collar of his robes! It is like the dew of Hermon, which falls on the mountains of Zion.” Psalm 133:2-3
Anointing was for those entering one of three offices in the Old Testament: Prophet, Priest, and King. It was always so that the person anointed could serve others.
A Symbolic Part: the oil used in anointing represents the Holy Spirit.
Oil was used for light. Oil lamps had a wick that would burn and give light like a candle. Think of the tongues of fire that appeared over the disciples’ heads on the day of Pentecost. In the Old Testament when the oil was poured over the head of one to be anointed the Spirit also was poured out so that person could serve God’s people. Prophets, priests and kings each served in specific ways. Jesus was anointed without measure, to serve as our Prophet, Priest and King.
