First Reading Phil 3:3-8a
For we are the circumcision, who in spirit serve God; and glory in Christ Jesus, not having confidence in the flesh. Though I might also have confidence in the flesh. If any other thinketh he may have confidence in the flesh, I more, Being circumcised the eighth day, of the stock of Israel, of the tribe of Benjamin, an Hebrew of the Hebrews; according to the law, a Pharisee: According to zeal, persecuting the church of God; according to the justice that is in the law, conversing without blame. But the things that were gain to me, the same I have counted loss for Christ. Furthermore I count all things to be but loss for the excellent knowledge of Jesus Christ my Lord; for whom I have suffered the loss of all things, and count them but as dung, that I may gain Christ:
Responsorial Psalm Ps 105:2-3, 4-5, 6-7
Sing to him, yea sing praises to him: relate all his wondrous works. Glory ye in his holy name: let the heart of them rejoice that seek the Lord.
Seek ye the Lord, and be strengthened: seek his face evermore. Remember his marvellous works which he hath done; his wonders, and the judgments of his mouth.
O ye seed of Abraham his servant; ye sons of Jacob his chosen. He is the Lord our God: his judgments are in all the earth.
Gospel Luke 15:1-10
Now the publicans and sinners drew near unto him to hear him. And the Pharisees and the scribes murmured, saying: This man receiveth sinners, and eateth with them. And he spoke to them this parable, saying: What man of you that hath an hundred sheep: and if he shall lose one of them, doth he not leave the ninety-nine in the desert, and go after that which was lost, until he find it? And when he hath found it, lay it upon his shoulders, rejoicing: And coming home, call together his friends and neighbours, saying to them: Rejoice with me, because I have found my sheep that was lost? I say to you, that even so there shall be joy in heaven upon one sinner that doth penance, more than upon ninety-nine just who need not penance. Or what woman having ten groats; if she lose one groat, doth not light a candle, and sweep the house, and seek diligently until she find it? And when she hath found it, call together her friends and neighbours, saying: Rejoice with me, because I have found the groat which I had lost. So I say to you, there shall be joy before the angels of God upon one sinner doing penance.
