OLD TESTAMENT   Exodus 24: 12 - 18   (RCL)

Exod 24:12 (NRSV) The LORD said to Moses, "Come up to me on the mountain, and wait there; and I will give you the tablets of stone, with the law and the commandment, which I have written for their instruction." 13 So Moses set out with his assistant Joshua, and Moses went up into the mountain of God. 14 To the elders he had said, "Wait here for us, until we come to you again; for Aaron and Hur are with you; whoever has a dispute may go to them." 
15 Then Moses went up on the mountain, and the cloud covered the mountain. 16 The glory of the LORD settled on Mount Sinai, and the cloud covered it for six days; on the seventh day he called to Moses out of the cloud. 17 Now the appearance of the glory of the LORD was like a devouring fire on the top of the mountain in the sight of the people of Israel. 18 Moses entered the cloud, and went up on the mountain. Moses was on the mountain for forty days and forty nights. 

OLD TESTAMENT: Leviticus 19:1-2, 9-18   (alt. for Can. BAS)
                                   Leviticus 19:1-2, 17-18   (Roman Catholic)

19:1 (NRSV) The Lord spoke to Moses, saying:
  2 Speak 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.

9 When 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. 10Y ou 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.
  11 You shall not steal; you shall not deal falsely; and you shall not lie to one another. 12 And you shall not swear falsely by my name, profaning the name of your God: I am the Lord.
  13 You shall not defraud your neighbor; you shall not steal; and you shall not keep for yourself the wages of a laborer until morning. 14 You shall not revile the deaf or put a stumbling-block before the blind; you shall fear your God: I am the Lord.
  15 You shall not render an unjust judgement; you shall not be partial to the poor or defer to the great: with justice you shall judge your neighbor. 16 You 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.
  17 You shall not hate in your heart anyone of your kin; you shall reprove your neighbor, or you will incur guilt yourself. 18 You 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. 

PSALM 2   (RCL)

Psal 2:1 (NRSV) Why do the nations conspire, 
and the peoples plot in vain? 
2 The kings of the earth set themselves, 
and the rulers take counsel together, 
against the LORD and his anointed, saying, 
3 "Let us burst their bonds asunder, 
and cast their cords from us." 
4 He who sits in the heavens laughs; 
the LORD has them in derision. 
5 Then he will speak to them in his wrath, 
and terrify them in his fury, saying, 
6 "I have set my king on Zion, my holy hill." 
7 I will tell of the decree of the LORD 
He said to me, "You are my son; 
today I have begotten you. 
8 Ask of me, and I will make the nations your heritage, 
and the ends of the earth your possession. 
9 You shall break them with a rod of iron, 
and dash them in pieces like a potter's vessel." 
10 Now therefore, O kings, be wise; 
be warned, O rulers of the earth. 
11 Serve the LORD with fear, 
with trembling 12 kiss his feet, 
or he will be angry, and you will perish in the way; 
for his wrath is quickly kindled. 
Happy are all who take refuge in him. 

2   Quare fremuerunt gentes?     (ECUSA BCP)
 
1  	Why are the nations in an uproar? *
 	Why do the peoples mutter empty threats?
 
2  	Why do the kings of the earth rise up in revolt,
and the princes plot together, *
 	against the Lord and against his Anointed?
 
3 	“Let us break their yoke,” they say; *
 	“let us cast off their bonds from us.”
 
4  	He whose throne is in heaven is laughing; *
 	the Lord has them in derision.
 
5  	Then he speaks to them in his wrath, *
 	and his rage fills them with terror.
 
6 	“I myself have set my king *
 	upon my holy hill of Zion.”
 
7  	Let me announce the decree of the Lord: *
 	he said to me, “You are my Son;
 	this day have I begotten you.
 
8  	Ask of me, and I will give you the nations for
		your inheritance *
 	and the ends of the earth for your possession.
 
9  	You shall crush them with an iron rod *
 	and shatter them like a piece of pottery."
 
10 	And now, you kings, be wise; *
 	be warned, you rulers of the earth.
 
11 	Submit to the Lord with fear, *
 	and with trembling bow before him;
 
12 	Lest he be angry and you perish; *
 	for his wrath is quickly kindled.
13  	Happy are they all *
 	who take refuge in him!

Psalm 99   (alt. for RCL)

Psal 99:1 (NRSV) The LORD is king; let the peoples tremble! 
He sits enthroned upon the cherubim; let the earth quake! 
2 The LORD is great in Zion; 
he is exalted over all the peoples. 
3 Let them praise your great and awesome name. 
Holy is he! 
4 Mighty King, lover of justice, 
you have established equity; 
you have executed justice 
and righteousness in Jacob. 
5 Extol the LORD our God; 
worship at his footstool. 
Holy is he! 
6 Moses and Aaron were among his priests, 
Samuel also was among those who called on his name. 
They cried to the LORD, and he answered them. 
7 He spoke to them in the pillar of cloud; 
they kept his decrees, 
and the statutes that he gave them. 
8 O LORD our God, you answered them; 
you were a forgiving God to them, 
but an avenger of their wrongdoings. 
9 Extol the LORD our God, 
and worship at his holy mountain; 
for the LORD our God is holy. 

99   Dominus regnavit   (ECUSA BCP)

let the people tremble; *
 	he is enthroned upon the cherubim;
 	let the earth shake.
 
2  	The Lord is great in Zion; *
 	he is high above all peoples.
 
3  	Let them confess his Name, which is great and awesome; *
 	he is the Holy One.

you have established equity; *
 	you have executed justice and righteousness in Jacob."
 
5  	Proclaim the greatness of the Lord our God
and fall down before his footstool; *
 	he is the Holy One.
 
6  	Moses and Aaron among his priests,
and Samuel among those who call upon his Name, *
 	they called upon the Lord, and he answered them.
 
7  	He spoke to them out of the pillar of cloud; *
 	they kept his testimonies and the decree that he gave them.
 
8  	"O Lord our God, you answered them indeed; *
 	you were a God who forgave them,
 	yet punished them for their evil deeds."
 
9  	Proclaim the greatness of the Lord our God
and worship him upon his holy hill; *
 	for the Lord our God is the Holy One.

119   (alt. for Can. BAS)

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.

NEW TESTAMENT   2 Peter 1: 16 - 21   (RCL)

2Pet 1:16 (NRSV) For we did not follow cleverly devised myths when we made known to you the power and coming of our Lord Jesus Christ, but we had been eyewitnesses of his majesty. 17 For he received honor and glory from God the Father when that voice was conveyed to him by the Majestic Glory, saying, "This is my Son, my Beloved, with whom I am well pleased." 18 We ourselves heard this voice come from heaven, while we were with him on the holy mountain. 
19 So we have the prophetic message more fully confirmed. You will do well to be attentive to this as to a lamp shining in a dark place, until the day dawns and the morning star rises in your hearts. 20 First of all you must understand this, that no prophecy of scripture is a matter of one's own interpretation, 21 because no prophecy ever came by human will, but men and women moved by the Holy Spirit spoke from God. 

1 Corinthians 3:10-11, 16-23   (alt. for Can. BAS)
1 Corinthians 3:16-23   (Roman Catholic)

3:10 (NRSV) 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. 11 For 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?* 17 If 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. 19 For the wisdom of this world is foolishness with God. For it is written,
  ‘He catches the wise in their craftiness’,
20 and again,
  ‘The Lord knows the thoughts of the wise,
   that they are futile.’
21 So let no one boast about human leaders. For all things are yours, 22 whether 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. 

GOSPEL   Matthew 17: 1 - 9   (RCL)

Matt 17:1 (NRSV) Six days later, Jesus took with him Peter and James and his brother John and led them up a high mountain, by themselves. 2 And he was transfigured before them, and his face shone like the sun, and his clothes became dazzling white. 3 Suddenly there appeared to them Moses and Eli'jah, talking with him. 4 Then Peter said to Jesus, "Lord, it is good for us to be here; if you wish, I will make three dwellings here, one for you, one for Moses, and one for Eli'jah." 5 While he was still speaking, suddenly a bright cloud overshadowed them, and from the cloud a voice said, "This is my Son, the Beloved; with him I am well pleased; listen to him!" 6 When the disciples heard this, they fell to the ground and were overcome by fear. 7 But Jesus came and touched them, saying, "Get up and do not be afraid." 8 And when they looked up, they saw no one except Jesus himself alone. 
9 As they were coming down the mountain, Jesus ordered them, "Tell no one about the vision until after the Son of Man has been raised from the dead." 10 And the disciples asked him, "Why, then, do the scribes say that Eli'jah must come first?" 

Matthew 5:38-48   (Roman Catholic; alt. for Can. BAS)

5:38 (NRSV) ‘You have heard that it was said, “An eye for an eye and a tooth for a tooth.” 39 But I say to you, Do not resist an evildoer. But if anyone strikes you on the right cheek, turn the other also; 40 and 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. 42 Give 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.” 44 But 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. 46 For if you love those who love you, what reward do you have? Do not even the tax-collectors do the same? 47 And if you greet only your brothers and sisters, what more are you doing than others? Do not even the Gentiles do the same? 48 Be perfect, therefore, as your heavenly Father is perfect.
