Nor less evident is the singular dignity of what is here promised to him. First of all, it is the fruit of the prayer of Christ. Of what importance must that be which was solicited by our Lord of His Father, and at a moment when the redemption of the world was being accomplished, and when His passion may be said to have begun? Of what importance that which was to be the defence of not Peter only, but all the disciples, against the most formidable assault of the great enemy, who had[29] demanded them as it were to deliver them over to punishment? And this was "that thy faith fail not." How is it possible to draw any other conclusion here than what S. Leo in the fifth century expressed so clearly before all the bishops of Italy? "The danger from the temptation of fear was common to all the Apostles, and all equally needed the help of the divine protection, since the devil desired to dismay all, to crush all; and yet a special care of Peter is undertaken by our Lord, and He prays peculiarly for the faith of Peter, as if the state of the rest would be more sure, if the mind of their chief were not conquered. In Peter, therefore, the fortitude of all is protected, and the help of divine grace is so ordered, that the firmness which through Christ is given to Peter, through Peter is conferred on the Apostles."[30] And if such is the importance of the help secured, no less is the charge following: "And thou, being once converted, confirm thy brethren." To confirm others, is to be put in an office of dignity and authority over them. And his brethren were those whom our Lord till now had been addressing in common with him; to whom He had just disclosed "a Greater" and "a Ruler" "among" them; that is, the Apostles themselves. Among these, then, when our Lord's visible presence was withdrawn, Peter was to be the principle of stability, binding and moulding them into one building. For one cannot fail to see how this great promise and prophecy answer to those in Matthew. There our Lord, as Architect, promised to lay Peter as the foundation of the Church, against which the gates of hell should not prevail: here, being about to leave the world, when His own work was finished, to ascend unto His Father, and to assume His great power and reign, He makes Peter as it were the Architect to carry on the work which was to be completed by _His_ grace and authority, but by human co-operation. So exact is the resemblance that we may put the two promises in parallel columns to illustrate each other: Thou art Peter, and upon But I have prayed for this Rock I will build My thee that thy faith fail not; Church; and the gates of hell and thou, being once converted, shall not prevail against it. confirm thy brethren.
