Summary: Since Jesus, the Good Shepherd, spared no pain to find the lost sheep, so Christ’s church will diligently use God’s law and gospel to call the erring brother to repentance. The object is always to win the brother over. The church speaks with Christ’s full authority when it declares God’s judgment upon the impenitent sinner and pronounces full forgiveness to the penitent sinner.
