First reading Philippians 3:3-8
I was faultless according to the Law; but without knowing Christ I was nothing
We are the real people of the circumcision, we who worship in accordance with the Spirit of God; we have our own glory from Christ Jesus without having to rely on a physical operation. If it came to relying on physical evidence, I should be fully qualified myself. Take any man who thinks he can rely on what is physical: I am even better qualified. I was born of the race of Israel and of the tribe of Benjamin, a Hebrew born of Hebrew parents, and I was circumcised when I was eight days old. As for the Law, I was a Pharisee; as for working for religion, I was a persecutor of the Church; as far as the Law can make you perfect, I was faultless. But because of Christ, I have come to consider all these advantages that I had as disadvantages. Not only that, but I believe nothing can happen that will outweigh the supreme advantage of knowing Christ Jesus my Lord.
Responsorial Psalm 104(105):2-7
Let the hearts that seek the Lord rejoice.
or
Alleluia!
O sing to the Lord, sing his praise;
tell all his wonderful works!
Be proud of his holy name,
let the hearts that seek the Lord rejoice.
Consider the Lord and his strength;
constantly seek his face.
Remember the wonders he has done,
his miracles, the judgements he spoke.
O children of Abraham, his servant,
O sons of the Jacob he chose.
He, the Lord, is our God:
his judgements prevail in all the earth.
Gospel Luke 15:1-10
There will be rejoicing in heaven over one repentant sinner
The tax collectors and the sinners were all seeking the company of Jesus to hear what he had to say, and the Pharisees and the scribes complained. ‘This man’ they said ‘welcomes sinners and eats with them.’ So he spoke this parable to them:
‘What man among you with a hundred sheep, losing one, would not leave the ninety-nine in the wilderness and go after the missing one till he found it? And when he found it, would he not joyfully take it on his shoulders and then, when he got home, call together his friends and neighbours? “Rejoice with me,” he would say “I have found my sheep that was lost.” In the same way, I tell you, there will be more rejoicing in heaven over one repentant sinner than over ninety-nine virtuous men who have no need of repentance.
‘Or again, what woman with ten drachmas would not, if she lost one, light a lamp and sweep out the house and search thoroughly till she found it? And then, when she had found it, call together her friends and neighbours? “Rejoice with me,” she would say “I have found the drachma I lost.” In the same way, I tell you, there is rejoicing among the angels of God over one repentant sinner.’
