There is yet something to be said about the relation of the pastoral office of the Church to the Head of the Church. St. John tells us (xxi, 15 ff.) that the risen Christ enjoined the apostle Peter: “Feed my lambs, feed my sheep.” Peter is not to feed his own sheep, but Christ’s sheep. So that the pastoral authority is plainly a delegated authority, and the pastor a deputy of Christ. That is the sort of authority which St. Paul exercises against the incestuous Corinthian; he gives him over “to Satan for the destruction of the flesh, that the spirit may be saved in the day of our Lord Jesus Christ,” and he does this “in the name of our Lord Jesus Christ” and “with the power of our Lord Jesus.” Every disciplinary measure of the Church is inspired by her conviction that she is acting in the name and in the power of Jesus. It is true that the pastoral authority of the Church does not, like her teaching or priestly authority, point directly to certain supernatural realities which have been determined once for all by Christ’s revelation, to the realities that is of doctrine and sacrament. Its object is rather to introduce these supernatural realities into practical life, to apply Christian rules and principles to the progressive and constantly changing life of nations and individuals. And in consequence there is no absolute certainty that all the particular measures of the pastoral authority are according to the mind and spirit of Christ.
