John 10:16

And other sheep I have, &c. Other sheep, i.e., those who will be My sheep. This is spoken by anticipation. He means the Gentiles, and thus predicts their call and conversion, to show that He was to be the King and Shepherd of all nations, just as up to this time He had been of the Jews: and that, consequently, He did not care (comparatively) whether the Jews (few as they were in number) would be unbelieving and rebellious, since He was about to put countless Gentiles in their place. So Rupertus, who adds, "and they will hear My voice," striking quietly at the Jews.

And there will be one fold, and one shepherd. Some suppose that in the end of the world, God will convert all the Jews by Elias, and all the Gentiles by Enoch, and thus there will become one Church, made up of them both, and one Pastor, Christ, and His Vicar the Supreme Pontiff, who will be called the Angelic Pastor. (See the list of hopes, described symbolically, in the life of S. Malachi.) But they are in error. For neither will Elias convert all the Jews, nor Enoch all the Gentiles. For there will be then many unbelievers and followers of antichrist. But this is far from being the meaning of Christ. It was, that after His death and resurrection His apostles would be dispersed among all nations, and convert them, so that both Jews and Gentiles would be gathered into one Church of believers, under one Shepherd, Christ, and His Vicar, the Roman Pontiff. This is not to be looked forward to as something future, for it took place in the time of Constantine the first Christian emperor, who christianised nearly all the nations which were subject to him. The Apostle graphically sets this before us (Ephesians 2) Ver. 17. Therefore doth My Father love me, &c. Lest the Jews should despise Him as a mere man who would die on the Cross, He meets the objection by saying that His death would be glorious, and an object of desire, because He could of His own accord submit to it from love of, and obedience to the Father, and therefore to be loved, honoured, and exalted, that at the Name of Jesus every knee should bow, &c. (Phi 2:10).

I lay down My life, i.e., My soul. So S. Augustine and others, who from this passage prove that Christ had a human soul, in opposition to Apollinarius, who maintained that His Divinity was in the place of a soul. But others understand by it "life," which is caused by the union of soul and body. It comes to the same thing. That I may take it again. I do not destroy it but only lay it aside for a short time, that I may rise and take it again. S. Cyril refers back to the words "My Father loveth Me." He loves Me not merely because I set My sheep free by My death, but also because I quicken them by My rising again. As S. Paul says, Rom. iv. 25.
