A Living Sacrifice
By Jeff Peterson, Professor of New Testament
Our chapel theme for 2026–27 is taken from the opening of Romans, chapter 12. This is the beginning of the “So what?” section of Paul’s most systematically argued letter, following the most expansive presentation of the gospel we have from his pen in chapters 1–11. As many commentators note, the little word translated “therefore” in many versions (Greek oun) closely connects the new section of the letter, and Paul’s appeal for transformation in its opening verses, to the preceding exposition of how God has acted to deliver humankind from the enslaving powers of Sin and Death through the crucifixion and resurrection of Jesus the Messiah and the pouring of his transforming Spirit into our hearts. The “mercies of God” (Rom 12:1) open up the possibility of new life for us now and impel us to pursue it.
The gospel, then, is not just a set of propositions to be believed; it is the announcement of a new creation into which God has introduced us by raising Jesus from the dead and of a new life that God empowers in us through the Spirit of his risen Son. In Romans, Paul urges his audience to embrace this gift from God using an image drawn from the practice of temple sacrifice, the central practice of ancient religion. The Romans are impelled “by the mercies of God to present your bodies as a living sacrifice” (Rom 12:1). Just as priests in the temple offered the bodies of animals in sacrifice, so Christians are to make our bodies an offering of thanks to the God who has shown us mercy in Christ.
Some commentators suggest that “bodies” here has a broader sense than its common reference to the physical body as one aspect of our human being, but I can’t find anything in the text to suggest this. Rather, with the image of a “living sacrifice” Paul recalls his earlier exhortation to “let not sin reign in your mortal bodies, to make you obey their passions” (Rom 6:12) and to “not yield your members to sin as instruments of wickedness, but yield yourselves to God as those who have been brought from death to life, and your members to God as instruments of righteousness” (Rom 6:13).
The “obedience of faith” (or, better, “obedience of trust”) that Paul’s gospel has produced across the eastern Mediterranean (Rom 1:5) begins, to be sure, with the purification of the heart (cf. Rom 2:25–29, echoing Deut 30:6–8), but as Paul details in chap. 6, in the course of the Christian life it also extends to submitting the “members” or “limbs” of our “bodies” to God. Christians being transformed by the grace of God in Christ don’t use our lips and tongues to impugn God among the nations, nor our hands to steal, nor our limbs to commit adultery, nor our hearts to covet. We are thus called by the gospel to “render” or “offer” the whole of our existence in the body as an offering to God in gratitude for the new life bestowed on us in Christ. Nor is this a solo project; in Romans 12, we all together offer our bodies in one “living sacrifice” as our “reasonable service” in the spiritual temple constituted by the church.
The image of a “living sacrifice” is puzzling; how can a sacrifice go on living? We might think here of the bush in which God appeared to Moses, which was “burning but not consumed” (Exod 3:2). Just as the fire in which God revealed himself burned, but the bush continued to exist, so we offer ourselves entirely to God, and “the life that I now live in the flesh, I live in the trust of the Son of God, who loved me and gave himself for me” (Gal 2:20). Christians are called to live “always carrying about the death of Christ in our body, that the life of Christ may be manifested in our bodies” (2 Cor 4:10). May the Spirit of God continue to transform us into the image of his Son in the days and months ahead, so that we may truly live as sacrifices and offer our bodies to him as instruments of his righteousness.
