Believers are “living stones” because of their faith in the resurrected Christ. Jesus’ resurrection life becomes theirs, even while they live in the midst of a hostile world. They await their resurrection at the end of the age, but even now because they have come to Christ (v. 4) they have new life. Nowhere else in the New Testament are believers called living stones, though elsewhere they are described as God’s temple or house (1 Cor 3:16; 6:19; Eph 2:19–22; Heb 3:6). The picture here is of a house in which believers constitute the building stones. The term “house” (oikos) alludes to the temple, which is commonly called a “house” in the Old Testament (e.g., 2 Sam 7:13; 1 Kgs 3:2; 6; 8, etc.) and is also designated as a house in the New Testament (Matt 21:13; 23:38; John 2:16–17; Acts 7:47, 49). In particular, when the verb “build” (oikodomeō) is combined with “house” (oikos) in the Septuagint, the temple is often in view. The house is “spiritual” (pneumatikos) because it is animated and indwelt by the Holy Spirit. Despite the hesitation of some scholars, Peter clearly here identified the church as God’s new temple.216 The physical temple pointed toward and anticipated God’s new temple, and now that the new temple has arrived, the old is superfluous
Peter was not thinking mainly of each individual functioning as a priest before God. The focus here is on the church corporately as God’s set-apart priesthood in which the emphasis is likely on believers functioning as priests
The parallel with 2:9, where the royal priesthood proclaims God’s wonders, suggests to some that this is the primary function of the priesthood (see commentary on 2:9 for further discussion). The priestly calling of the church is understood from 2:9 to be evangelistic, a praising of God’s name so that people from all over the world will join in worshiping him. Nevertheless, we should not limit the sacrifices here to any one item, for everything that is pleasing to God is probably included (cf. Rom 12:1; Heb 13:15–16). Peter spoke generally and comprehensively of all that believers do by the power of the Holy Spirit.232 Indeed, not any and every sacrifice is pleasing to God, but only those offered “through Jesus Christ.”
Their stumbling over the cornerstone is not accidental, as humans often trip unintentionally while walking. In this instance humans stumble because of rebellion, because they do not want to submit to God’s lordship
As noted above, the priesthood here is corporate in nature, and yet this does not rule out the truth that individuals serve priestly functions. Best seems to strike the right balance here: “Christians exercise priestly functions but always as members of a group who all exercise the same function
The purpose of the people of God is now explained. God has chosen them to be his people, established them as a royal priesthood, appointed them as a holy nation to be his special possession, so that they would “declare the praises of him who called you out of darkness into his wonderful light.” Peter again probably alluded to Isa 43:21, for there we are told that God formed Israel for himself so that “they would recount my praises
