First Reading 1 Corinthians 4:6-15

6I have applied all this to myself and Apol'los for your benefit, brethren, that you may learn by us not to go beyond what is written, that none of you may be puffed up in favor of one against another. 7For who sees anything different in you? What have you that you did not receive? If then you received it, why do you boast as if it were not a gift? 8Already you are filled! Already you have become rich! Without us you have become kings! And would that you did reign, so that we might share the rule with you! 9For I think that God has exhibited us apostles as last of all, like men sentenced to death; because we have become a spectacle to the world, to angels and to men. 10We are fools for Christ's sake, but you are wise in Christ. We are weak, but you are strong. You are held in honor, but we in disrepute. 11To the present hour we hunger and thirst, we are ill-clad and buffeted and homeless, 12and we labor, working with our own hands. When reviled, we bless; when persecuted, we endure; 13when slandered, we try to conciliate; we have become, and are now, as the refuse of the world, the offscouring of all things. 14I do not write this to make you ashamed, but to admonish you as my beloved children. 15For though you have countless guides in Christ, you do not have many fathers. For I became your father in Christ Jesus through the gospel.

Responsorial Psalm Psalms 145:17-21

17The LORD is just in all his ways, and kind in all his doings. 18The LORD is near to all who call upon him, to all who call upon him in truth. 19He fulfils the desire of all who fear him, he also hears their cry, and saves them. 20The LORD preserves all who love him; but all the wicked he will destroy. 21My mouth will speak the praise of the LORD, and let all flesh bless his holy name for ever and ever.

Gospel Luke 6:1-5

1On a sabbath, while he was going through the grainfields, his disciples plucked and ate some heads of grain, rubbing them in their hands. 2But some of the Pharisees said, "Why are you doing what is not lawful to do on the sabbath?" 3And Jesus answered, "Have you not read what David did when he was hungry, he and those who were with him: 4how he entered the house of God, and took and ate the bread of the Presence, which it is not lawful for any but the priests to eat, and also gave it to those with him?" 5And he said to them, "The Son of man is lord of the sabbath."
