How do we know that the doctrine of Christ’s perfect sacrifice is true?

The doctrine of Christ’s perfect sacrifice is firmly rooted in Scripture and is confirmed by both Old Testament types and New Testament fulfillment. The repeated emphasis in passages such as Leviticus and Exodus is that sacrifices must be without blemish (Leviticus 1:3; Exodus 12:5), symbolizing the ultimate sacrifice that Christ would make on our behalf. In 1 Peter 1:18-19, the apostle Peter articulates that we are redeemed not with corruptible things but with the precious blood of Christ, affirming that His sacrifice met the divine requirements laid out in the Old Testament. This consistency in God's plan across both Testaments underscores the truth of Christ’s role as our sufficient and perfect sacrifice.
