First Reading Isa 52:7-10
How beautiful upon the mountains are the feet of him that bringeth good tidings, and that preacheth peace: of him that sheweth forth good, that preacheth salvation, that saith to Sion: Thy God shall reign! The voice of thy watchmen: they have lifted up their voice, they shall praise together: for they shall see eye to eye when the Lord shall convert Sion. Rejoice, and give praise together, O ye deserts of Jerusalem: for the Lord hath comforted his people: he hath redeemed Jerusalem. The Lord hath prepared his holy arm in the sight of all the Gentiles: and all the ends of the earth shall see the salvation of our God.

Say ye among the Gentiles, the Lord hath reigned. For he hath corrected the world, which shall not be moved: he will judge the people with justice.

He saith to him: Feed my lambs. He saith to him again: Simon, son of John, lovest thou me? He saith to him: Yea, Lord, thou knowest that I love thee. He saith to him: Feed my lambs. He said to him the third time: Simon, son of John, lovest thou me? Peter was grieved, because he had said to him the third time: Lovest thou me? And he said to him: Lord, thou knowest all things: thou knowest that I love thee. He said to him: Feed my sheep .
