Jesus is not only the final prophet; he is also our great high priest. How is Christ a priest? The child responds in the catechism, “Because he died for our sins and pleads with God for us.” This death for sins was an efficacious sacrifice (Heb 7:25-28). Christ is now seated at God’s right hand as our sympathetic priest (Heb 4:14-16).
“Why do I need Christ as a priest?” The child’s answer: “Because I am sinful.” The call of the gospel is not to those who are strong and proud, but to those who are humble. The warning of Hebrews 2:1 is for us: “Let us pay much closer attention!” We can only find forgiveness of sins in Christ, our only true priest.
Once forgiven, as God’s people, we are to function as a kingdom of priests, offering sacrifices of praise (Heb. 13:15; 1 Peter 2:5), the sacrifices of goodness and sharing with others (Heb. 13:16), and doing the priestly work of announcing to others forgiveness in Christ (1 Peter 2:9).
