Scripture speaks both of Christ’s sacrifice for sinners and of sacrifices Christians offer to God. Confusing those uses can burden a conscience with work that only Christ can do. Distinguishing them also restores the proper place of praise and service.
The Word
θυσία (thysia) means sacrifice or offering. It is a noun used for offerings in the temple, Christ’s self-offering, and the praise and good works of God’s people.
The noun alone does not tell us whether an offering atones for sin. The person offering, the gift offered, and the purpose identified in the passage determine how the word functions.
Range of Meaning
Hebrews 10 contrasts repeated sacrifices with Christ’s one sacrifice for sins. Romans 12:1 calls Christians to present their bodies as a living sacrifice. Philippians 4:18 applies sacrificial language to material support sent to Paul.
Those passages do not establish multiple interchangeable ways to obtain forgiveness. They show how sacrifice language can describe both the saving work from which Christian life flows and the grateful service that follows it.
Where You’ll Meet It
Hebrews exhorts believers:
“Through him then let us continually offer up a sacrifice of praise to God” (Hebrews 13:15, NET)
The verse explains this praise as the fruit of lips acknowledging God’s name. The next verse includes doing good and sharing. Worship and the practical care of neighbors belong within the life sustained by Christ.
The opening words, through him, matter. Christians do not leave their mediator behind when they begin thanking God. Their access remains through Christ, even when the subject shifts from receiving mercy to expressing gratitude.
What Confessional Lutherans Hear
An atoning sacrifice obtains reconciliation; a sacrifice of thanksgiving responds to reconciliation received. Christ’s self-offering is sufficient for sinners. Our prayers, praise, gifts, and acts of mercy do not supplement it or make it effective.
This does not make Christian service dispensable. Augsburg Confession VI teaches that faith should bear the good works God commands, while refusing to place trust in them as a means of earning grace. That is the distinction the troubled conscience needs and the complacent life must also hear.
The Lord’s Supper belongs first to Christ’s giving. Augsburg Confession X confesses the true body and blood distributed and received there. The congregation certainly gives thanks, but its thanksgiving must not displace the gift or turn the sacrament into our payment for forgiveness.
Where People Get It Wrong
Calling worship a sacrifice does not by itself make it an atoning work. Conversely, saying that Christ alone atones does not mean that the New Testament forbids every use of sacrificial language for Christians.
The practical question is whether the work is being offered as a purchase of God’s favor or as the fruit of his favor already given in Christ. The same outward activity can be badly misunderstood when that order is reversed.
So What
Sing, pray, give, and help the person who needs you. These are substantial gifts of time, strength, and resources. They need not become payments toward a debt Christ has already borne.
When conscience asks what reconciles you to God, point to Christ. When your neighbor asks for help, use the gifts he has put in your hands. Ephapax explains why his saving sacrifice needs no repetition.
