First Reading Revelation 3:7-8, 10-12

7"And to the angel of the church in Philadelphia write: `The words of the holy one, the true one, who has the key of David, who opens and no one shall shut, who shuts and no one opens. 8"`I know your works. Behold, I have set before you an open door, which no one is able to shut; I know that you have but little power, and yet you have kept my word and have not denied my name. 10Because you have kept my word of patient endurance, I will keep you from the hour of trial which is coming on the whole world, to try those who dwell upon the earth. 11I am coming soon; hold fast what you have, so that no one may seize your crown. 12He who conquers, I will make him a pillar in the temple of my God; never shall he go out of it, and I will write on him the name of my God, and the name of the city of my God, the new Jerusalem which comes down from my God out of heaven, and my own new name.

Responsorial Psalm Psalms 119:137-144

137Righteous art thou, O LORD, and right are thy judgments. 138Thou hast appointed thy testimonies in righteousness and in all faithfulness. 139My zeal consumes me, because my foes forget thy words. 140Thy promise is well tried, and thy servant loves it. 141I am small and despised, yet I do not forget thy precepts. 142Thy righteousness is righteous for ever, and thy law is true. 143Trouble and anguish have come upon me, but thy commandments are my delight. 144Thy testimonies are righteous for ever; give me understanding that I may live.

Gospel John 10:11-16

11I am the good shepherd. The good shepherd lays down his life for the sheep. 12He who is a hireling and not a shepherd, whose own the sheep are not, sees the wolf coming and leaves the sheep and flees; and the wolf snatches them and scatters them. 13He flees because he is a hireling and cares nothing for the sheep. 14I am the good shepherd; I know my own and my own know me, 15as the Father knows me and I know the Father; and I lay down my life for the sheep. 16And I have other sheep, that are not of this fold; I must bring them also, and they will heed my voice. So there shall be one flock, one shepherd.
