Perhaps no doctrine of the New Testament offers more sanctity to this fact than that the church is the body of Christ which he has purchased with his own blood. That which elders or bishops rule is the blood-purchased possession of Christ, that which cost the agony of Gethsemane and the blood of Calvary’s accursed tree. It was that which was captive to sin, Satan, and death, and Christ redeemed it as his own precious possession. It is now his body, and he is the head. How shall we dare to handle that body, how shall we dare to direct its affairs, except as we can plead the authority of Christ? The church as the body of Christ is not to be ruled according to human wisdom and expediency but according to the prescriptions of him in whom are hid all the treasures of wisdom and knowledge.” —John Murray, Government in the Church of Christ.
