Acts 10:38 → Psalms 45:6-7

Peter's summary — "how God anointed Jesus of Nazareth with the Holy Spirit and with power" (Acts 10:38) — names the very transaction Psalm 45:7b had compressed into the royal wedding: "God, your God, has anointed you above your companions with the oil of joy." The verbal link runs through the Septuagint, which renders the psalm ἔχρισέν σε ὁ θεός ("God has anointed you"), the same verb (χρίω) Luke uses of Jesus in Acts 10:38 (ἔχρισεν) — the root of the title Χριστός, the Anointed One. Where Psalm 45 names the agent of the anointing as the King's own God (Father to Son), Acts 10:38 names the means (the Holy Spirit) and the effect (a ministry of doing good and overpowering the devil). This is not a quotation but an echo within the Anointing longitudinal theme: the psalm's eternal-relational anointing of the divine Son stands behind the Spirit-anointing Peter preaches. The escalation is from the wedding-day oil of gladness poured on the enthroned King to the Spirit Himself resting on the incarnate Son in His public ministry. The telos: the Anointed One is not merely a commissioned functionary but the Son whom the Father delights to exalt "above his companions" — the Christ whose anointing overflows in gladness, so that He is seen as the desirable King under whose healing reign the oppressed are set free.
