Greek Key Terms:
Context: Peter addresses Gentile Christians scattered throughout Asia Minor (1:1), applying Israel's covenant identity directly to the church. The immediate context (2:4-10) develops the "living stones" metaphor: Christ is the cornerstone, believers are built into a spiritual house for a holy priesthood. Verse 9 quotes Exodus 19:6 (LXX verbatim: βασίλειον ἱεράτευμα) combined with Isaiah 43:20-21. The fourfold description—chosen race, royal priesthood, holy nation, people for possession—transfers Israel's identity to the church. The purpose: "that you may proclaim the excellencies of him who called you."

Connections:
Christological Connection: Christ is the cornerstone upon which the priestly house is built (2:4-8). Believers become "living stones" only through union with the "living stone" who was rejected by men but chosen and precious to God. The corporate priesthood exists to offer "spiritual sacrifices acceptable to God through Jesus Christ" (2:5)—all priestly access and service is mediated through Him. The "excellencies" (ἀρετάς) proclaimed are Christ's excellencies: His calling from darkness to light, His mercy that transforms non-people into God's people. The church's royal-priestly identity is derivative, participatory—we are priests because our High Priest has made us so through His blood.
Connection Method(s): Promise-Fulfillment, Longitudinal Theme — Peter explicitly applies Exodus 19:6 to the church, with believers becoming "living stones" and a "royal priesthood" through union with Christ the cornerstone.
