Circumcision is the law Christ said “is done away in me.” His instruction joins that declaration to the condition of little children: “the curse of Adam is taken from them in me, that it hath no power over them” (Moroni 8:8).
Christ says, “I came into the world not to call the righteous but sinners to repentance,” and that “little children are whole, for they are not capable of committing sin.” The instruction directs its hearers to “listen to the words of Christ” and calls him “your Redeemer, your Lord and your God” (Moroni 8:8).
