The following are the readings for the Second Sunday after Pentecost, May 25 (Proper 3), according to the Revised Common (RCL), Roman Catholic, Canadian BAS, and the Church of England (Common Worship) lectionaries.

This Sunday is celebrated as Corpus Christi in the Roman Catholic Church; this is optional in the C of E.

OLD TESTAMENT: Isaiah 49:8-16a    (RCL)

Isaiah 49: (NRSV) 8Thus says the Lord: In a time of favor I have answered you, on a day of salvation I have helped you; I have kept you and given you as a covenant to the people, to establish the land, to apportion the desolate heritages; 9saying to the prisoners, “Come out,” to those who are in darkness, “Show yourselves.” They shall feed along the ways, on all the bare heights shall be their pasture; 10they shall not hunger or thirst, neither scorching wind nor sun shall strike them down, for he who has pity on them will lead them, and by springs of water will guide them. 11And I will turn all my mountains into a road, and my highways shall be raised up. 12Lo, these shall come from far away, and lo, these from the north and from the west, and these from the land of Syene.

13Sing for joy, O heavens, and exult, O earth; break forth, O mountains, into singing! For the Lord has comforted his people, and will have compassion on his suffering ones. 14But Zion said, “The Lord has forsaken me, my Lord has forgotten me.” 15Can a woman forget her nursing child, or show no compassion for the child of her womb? Even these may forget, yet I will not forget you. 16See, I have inscribed you on the palms of my hands.

Leviticus 19:1-2, 9-18   (C of E, Can. BAS)

Lev 19:  (NRSV)  1 The Lord spoke to Moses, saying: 2Speak to all the congregation of the people of Israel and say to them: You shall be holy, for I the Lord your God am holy. 

9When you reap the harvest of your land, you shall not reap to the very edges of your field, or gather the gleanings of your harvest. 10You shall not strip your vineyard bare, or gather the fallen grapes of your vineyard; you shall leave them for the poor and the alien: I am the Lord your God.

11You shall not steal; you shall not deal falsely; and you shall not lie to one another. 12And you shall not swear falsely by my name, profaning the name of your God: I am the Lord. 13You shall not defraud your neighbor; you shall not steal; and you shall not keep for yourself the wages of a laborer until morning. 14You shall not revile the deaf or put a stumbling block before the blind; you shall fear your God: I am the Lord. 15You shall not render an unjust judgment; you shall not be partial to the poor or defer to the great: with justice you shall judge your neighbor. 16You shall not go around as a slanderer among your people, and you shall not profit by the blood of your neighbor: I am the Lord. 17You shall not hate in your heart anyone of your kin; you shall reprove your neighbor, or you will incur guilt yourself. 18You shall not take vengeance or bear a grudge against any of your people, but you shall love your neighbor as yourself: I am the Lord.

Deuteronomy 8:2-3, 14b-16a   (Roman Catholic)

Deut 8:  (NRSV)  2 Remember the long way that the Lord your God has led you these forty years in the wilderness, in order to humble you, testing you to know what was in your heart, whether or not you would keep his commandments. 3He humbled you by letting you hunger, then by feeding you with manna, with which neither you nor your ancestors were acquainted, in order to make you understand that one does not live by bread alone, but by every word that comes from the mouth of the Lord. 14then do not exalt yourself, forgetting the Lord your God, who brought you out of the land of Egypt, out of the house of slavery, 15who led you through the great and terrible wilderness, an arid wasteland with poisonous snakes and scorpions. He made water flow for you from flint rock, 16and fed you in the wilderness with manna that your ancestors did not know,

Genesis 14.18-20   (alt. for C of E)

Gen 14:  (NRSV)  18 And King Melchizedek of Salem brought out bread and wine; he was priest of God Most High.* 19He blessed him and said,
‘Blessed be Abram by God Most High,*
   maker of heaven and earth;
20and blessed be God Most High,*
   who has delivered your enemies into your hand!’
And Abram gave him one-tenth of everything.

PSALM 131   (RCL)

1O Lord, my heart is not lifted up, my eyes are not raised too high; I do not occupy myself with things too great and too marvelous for me.
2But I have calmed and quieted my soul, like a weaned child with its mother; my soul is like the weaned child that is with me.
3O Israel, hope in the Lord from this time on and forevermore. 

131   Domine, non est   (ECUSA BCP)
 
1  	O Lord, I am not proud; *
 	I have no haughty looks.
 
2  	I do not occupy myself with great matters, *
 	or with things that are too hard for me.
 
3  	But I still my soul and make it quiet,
like a child upon its mother's breast; *
 	my soul is quieted within me.
 
4  	O Israel, wait upon the Lord, *
 	from this time forth for evermore.

Psalm 119: 33-40   (C of E, Can. BAS; ECUSA BCP)

He   Legem pone
 
33  	Teach me, O Lord, the way of your statutes, *
 	and I shall keep it to the end.
 
34  	Give me understanding, and I shall keep your law; *
 	I shall keep it with all my heart.
 
35  	Make me go in the path of your commandments, *
 	for that is my desire.
 
36  	Incline my heart to your decrees *
 	and not to unjust gain.
 
37  	Turn my eyes from watching what is worthless; *
 	give me life in your ways.
 
38  	Fulfill your promise to your servant, *
 	which you make to those who fear you.
 
39  	Turn away the reproach which I dread, *
 	because your judgments are good.
 
40  	Behold, I long for your commandments; *
 	in your righteousness preserve my life.

Psalm 116: 10-17   (alt. for C of E)

10I kept my faith, even when I said,
   ‘I am greatly afflicted’;
11I said in my consternation,
   ‘Everyone is a liar.’

12What shall I return to the Lord
   for all his bounty to me?
13I will lift up the cup of salvation
   and call on the name of the Lord,
14I will pay my vows to the Lord
   in the presence of all his people.
15Precious in the sight of the Lord
   is the death of his faithful ones.
16O Lord, I am your servant;
   I am your servant, the child of your serving-maid.
   You have loosed my bonds.
17I will offer to you a thanksgiving sacrifice
   and call on the name of the Lord. 

Psalm 147: 12-15, 19-20   (Roman Catholic)

12    Glorify the LORD, Jerusalem; Zion, offer praise to your God,
13    Who has strengthened the bars of your gates, blessed your children within you,
14    Brought peace to your borders, and filled you with finest wheat.
15    The LORD sends a command to earth; his word runs swiftly!

19    The LORD also proclaims his word to Jacob, decrees and laws to Israel.
20    God has not done this for other nations; of such laws they know nothing. Hallelujah!

NEW TESTAMENT: 1 Corinthians 4:1-5   (RCL, Can. BAS)

(NRSV)  1Think of us in this way, as servants of Christ and stewards of God’s mysteries. 2Moreover, it is required of stewards that they be found trustworthy. 3But with me it is a very small thing that I should be judged by you or by any human court. I do not even judge myself. 4I am not aware of anything against myself, but I am not thereby acquitted. It is the Lord who judges me. 5Therefore do not pronounce judgment before the time, before the Lord comes, who will bring to light the things now hidden in darkness and will disclose the purposes of the heart. Then each one will receive commendation from God.

1 Corinthians 3: 10-11, 16-23   (C of E)

1 Cor 3:  (NRSV)  10 According to the grace of God given to me, like a skilled master builder I laid a foundation, and someone else is building on it. Each builder must choose with care how to build on it. 11For no one can lay any foundation other than the one that has been laid; that foundation is Jesus Christ.

16 Do you not know that you are God’s temple and that God’s Spirit dwells in you?* 17If anyone destroys God’s temple, God will destroy that person. For God’s temple is holy, and you are that temple.

18 Do not deceive yourselves. If you think that you are wise in this age, you should become fools so that you may become wise. 19For the wisdom of this world is foolishness with God. For it is written,
‘He catches the wise in their craftiness’,
20and again,
‘The Lord knows the thoughts of the wise,
   that they are futile.’
21So let no one boast about human leaders. For all things are yours, 22whether Paul or Apollos or Cephas or the world or life or death or the present or the future—all belong to you, 23and you belong to Christ, and Christ belongs to God.

1 Corinthians 11: 23-26   (alt. for C of E)

1 Cor 11:  (NRSV)  23 For I received from the Lord what I also handed on to you, that the Lord Jesus on the night when he was betrayed took a loaf of bread, 24and when he had given thanks, he broke it and said, ‘This is my body that is for* you. Do this in remembrance of me.’ 25In the same way he took the cup also, after supper, saying, ‘This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me.’ 26For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until he comes.

1 Corinthians 10:16-17   (Roman Catholic)

1 Cor 10:  (NRSV)  16The cup of blessing that we bless, is it not a sharing in the blood of Christ? The bread that we break, is it not a sharing in the body of Christ? 17Because there is one bread, we who are many are one body, for we all partake of the one bread.

GOSPEL: Matthew 6:24-34   (RCL)

Matt 6:  (NRSV)  24“No one can serve two masters; for a slave will either hate the one and love the other, or be devoted to the one and despise the other. You cannot serve God and wealth.

25“Therefore I tell you, do not worry about your life, what you will eat or what you will drink, or about your body, what you will wear. Is not life more than food, and the body more than clothing? 26Look at the birds of the air; they neither sow nor reap nor gather into barns, and yet your heavenly Father feeds them. Are you not of more value than they? 27And can any of you by worrying add a single hour to your span of life? 28And why do you worry about clothing? Consider the lilies of the field, how they grow; they neither toil nor spin, 29yet I tell you, even Solomon in all his glory was not clothed like one of these. 30But if God so clothes the grass of the field, which is alive today and tomorrow is thrown into the oven, will he not much more clothe you—you of little faith? 31Therefore do not worry, saying, ‘What will we eat?’ or ‘What will we drink?’ or ‘What will we wear?’ 32For it is the Gentiles who strive for all these things; and indeed your heavenly Father knows that you need all these things. 33But strive first for the kingdom of God and his righteousness, and all these things will be given to you as well. 34“So do not worry about tomorrow, for tomorrow will bring worries of its own. Today’s trouble is enough for today.

Matthew 5:38-48   (C of E, Can. BAS)

Matt 5:  (NRSV) 38“You have heard that it was said, ‘An eye for an eye and a tooth for a tooth.’ 39But I say to you, Do not resist an evildoer. But if anyone strikes you on the right cheek, turn the other also; 40and if anyone wants to sue you and take your coat, give your cloak as well; 41and if anyone forces you to go one mile, go also the second mile. 42Give to everyone who begs from you, and do not refuse anyone who wants to borrow from you.

43“You have heard that it was said, ‘You shall love your neighbor and hate your enemy.’ 44But I say to you, Love your enemies and pray for those who persecute you, 45so that you may be children of your Father in heaven; for he makes his sun rise on the evil and on the good, and sends rain on the righteous and on the unrighteous. 46For if you love those who love you, what reward do you have? Do not even the tax collectors do the same? 47And if you greet only your brothers and sisters, what more are you doing than others? Do not even the Gentiles do the same? 48Be perfect, therefore, as your heavenly Father is perfect.

John 6:51-58   (Roman Catholic, alt. for C of E)

John 6:  (NRSV)  51 I am the living bread that came down from heaven. Whoever eats of this bread will live forever; and the bread that I will give for the life of the world is my flesh.” 52The Jews then disputed among themselves, saying, “How can this man give us his flesh to eat?” 53So Jesus said to them, “Very truly, I tell you, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. 54Those who eat my flesh and drink my blood have eternal life, and I will raise them up on the last day; 55for my flesh is true food and my blood is true drink. 56Those who eat my flesh and drink my blood abide in me, and I in them. 57Just as the living Father sent me, and I live because of the Father, so whoever eats me will live because of me. 58This is the bread that came down from heaven, not like that which your ancestors ate, and they died. But the one who eats this bread will live forever.”
