God, the Finger of God, and The Son of Man
In Psalm 8, we see all Three Persons of the Trinity working in unison, let’s examine the psalm.
I. The Father – set His glory above the Heavens [v.1], established strength out of the mouth of infants and babes in order to still the enemy[v.2], set the universe in its place [v.3]; He is mindful of man/the Son of Man and cares for Him [v.4]; He has made Him a little lower than the angels [v.5], crowned Him with glory and honor [v.5], given Him dominion over all the works of creation [v.6], put all things under the Son of Man’s feet [v.6]
2. The Son – is shown care by the Father [v.4], made a little lower than the angels, crowned with glory and honor, and given dominion over all of creation [i.e. in the Incarnation, cf. v.5 and Hebrews 2:5-8, as well as Matthew 28:18, John 17:1-3, and 1 Corinthians 15:23-25]
Since Psalm 8 is understood as a Messianic psalm by the writer of the book of Hebrews, we would do well to understand it as such. And if Messianic, then touching upon the work of salvation. The Father planned, therefore, that Christ would be made a little lower than the angels, conceived of a virgin by the Holy Spirit, in order to suffer for the sins of God’s elect, and to then be raised to eternal life as the King of kings, reigning Sovereignly over all that has been placed under His feet. The Son is He who, although being in very essence God, humbled Himself and took on the form of a Servant, and suffered death upon the cross (cf. Phil 2:5-8), who was resurrected from the dead and given the name that is above all names (cf. Phil 2:9-11). And the Holy Spirit is He who hovered over the womb of Mary (cf. Luke 1:35), creating the physical body of the Second Person of the Trinity, who led Christ (cf. Matt 4:1), and through whom Christ walked perfectly before the Father (cf. John 3:34).
Praise Father, Son, and Holy Ghost!
