First Reading Ezekiel 18:25-28

25"Yet you say, `The way of the Lord is not just.' Hear now, O house of Israel: Is my way not just? Is it not your ways that are not just? 26When a righteous man turns away from his righteousness and commits iniquity, he shall die for it; for the iniquity which he has committed he shall die. 27Again, when a wicked man turns away from the wickedness he has committed and does what is lawful and right, he shall save his life. 28Because he considered and turned away from all the transgressions which he had committed, he shall surely live, he shall not die.

Responsorial Psalm Psalms 25:4-9

4Make me to know thy ways, O LORD; teach me thy paths. 5Lead me in thy truth, and teach me, for thou art the God of my salvation; for thee I wait all the day long. 6Be mindful of thy mercy, O LORD, and of thy steadfast love, for they have been from of old. 7Remember not the sins of my youth, or my transgressions; according to thy steadfast love remember me, for thy goodness' sake, O LORD! 8Good and upright is the LORD; therefore he instructs sinners in the way. 9He leads the humble in what is right, and teaches the humble his way.

Second Reading Philippians 2:1-11

1So if there is any encouragement in Christ, any incentive of love, any participation in the Spirit, any affection and sympathy, 2complete my joy by being of the same mind, having the same love, being in full accord and of one mind. 3Do nothing from selfishness or conceit, but in humility count others better than yourselves. 4Let each of you look not only to his own interests, but also to the interests of others. 5Have this mind among yourselves, which is yours in Christ Jesus, 6who, though he was in the form of God, did not count equality with God a thing to be grasped, 7but emptied himself, taking the form of a servant, being born in the likeness of men. 8And being found in human form he humbled himself and became obedient unto death, even death on a cross. 9Therefore God has highly exalted him and bestowed on him the name which is above every name, 10that at the name of Jesus every knee should bow, in heaven and on earth and under the earth, 11and every tongue confess that Jesus Christ is Lord, to the glory of God the Father.

Gospel Matthew 21:28-32

28"What do you think? A man had two sons; and he went to the first and said, `Son, go and work in the vineyard today.' 29And he answered, `I will not'; but afterward he repented and went. 30And he went to the second and said the same; and he answered, `I go, sir,' but did not go. 31Which of the two did the will of his father?" They said, "The first." Jesus said to them, "Truly, I say to you, the tax collectors and the harlots go into the kingdom of God before you. 32For John came to you in the way of righteousness, and you did not believe him, but the tax collectors and the harlots believed him; and even when you saw it, you did not afterward repent and believe him.
