First Reading: Isaiah 58: 9b-14
9b Thus says the Lord: If thou wilt take away the chain out of the midst of thee, and cease to stretch out the finger, and to speak that which profiteth not.

10 When thou shalt pour out thy soul to the hungry, and shalt satisfy the afflicted soul then shall thy light rise up in darkness, and thy darkness shall be as the noonday.

11 And the Lord will give thee rest continually, and will fill thy soul with brightness, and deliver thy bones, and thou shalt be like a watered garden, and like a fountain of water whose waters shall not fail.

12 And the places that have been desolate for ages shall be built in thee: thou shalt raise up the foundations of generation and generation: and thou shalt be called the repairer of the fences, turning the paths into rest.

13 If thou turn away thy foot from the sabbath, from doing thy own will in my holy day, and call the sabbath delightful, and the holy of the Lord glorious, and glorify him, while thou dost not thy own ways, and thy own will is not found: to speak a word:

14 Then shalt thou be delighted in the Lord, and I will lift thee up above the high places of the earth, and will feed thee with the inheritance of Jacob thy father. For the mouth of the Lord hath spoken it.

Responsorial Psalm: Psalms 86: 1-2, 3-4, 5-6
R. (11ab) Teach me your way, O Lord, that I may walk in your truth.

1 A prayer for David himself. Incline thy ear, O Lord, and hear me: for I am needy and poor.

2 Preserve my soul, for I am holy: save thy servant, O my God, that trusteth in thee.

R. Teach me your way, O Lord, that I may walk in your truth.

3 Have mercy on me, O Lord, for I have cried to thee all the day.

4 Give joy to the soul of thy servant, for to thee, O Lord, I have lifted up my soul.

R. Teach me your way, O Lord, that I may walk in your truth.

5 For thou, O Lord, art sweet and mild: and plenteous in mercy to all that call upon thee.

6 Give ear, O Lord, to my prayer: and attend to the voice of my petition.

R. Teach me your way, O Lord, that I may walk in your truth.
Verse Before the Gospel: Ezekiel 33: 11
11 I take no pleasure in the death of the wicked man, says the Lord, but rather in his conversion, that he may live.

Gospel: Luke 5: 27-32
27 And after these things he went forth, and saw a publican named Levi, sitting at the receipt of custom, and he said to him: Follow me.

28 And leaving all things, he rose up and followed him.

29 And Levi made him a great feast in his own house; and there was a great company of publicans, and of others, that were at table with them.

30 But the Pharisees and scribes murmured, saying to his disciples: Why do you eat and drink with publicans and sinners?

31 And Jesus answering, said to them: They that are whole, need not the physician: but they that are sick.

32 I came not to call the just, but sinners to penance.
