OLD TESTAMENT: Genesis 1:1 - 2:4a (RCL) 

Gene 1:1 (NRSV) In the beginning when God created the heavens and the earth, 2 the earth was a formless void and darkness covered the face of the deep, while a wind from God swept over the face of the waters. 3 Then God said, "Let there be light"; and there was light. 4 And God saw that the light was good; and God separated the light from the darkness. 5 God called the light Day, and the darkness he called Night. And there was evening and there was morning, the first day. 
6 And God said, "Let there be a dome in the midst of the waters, and let it separate the waters from the waters." 7 So God made the dome and separated the waters that were under the dome from the waters that were above the dome. And it was so. 8 God called the dome Sky. And there was evening and there was morning, the second day. 
9 And God said, "Let the waters under the sky be gathered together into one place, and let the dry land appear." And it was so. 10 God called the dry land Earth, and the waters that were gathered together he called Seas. And God saw that it was good. 11 Then God said, "Let the earth put forth vegetation: plants yielding seed, and fruit trees of every kind on earth that bear fruit with the seed in it." And it was so. 12 The earth brought forth vegetation: plants yielding seed of every kind, and trees of every kind bearing fruit with the seed in it. And God saw that it was good. 13 And there was evening and there was morning, the third day. 
14 And God said, "Let there be lights in the dome of the sky to separate the day from the night; and let them be for signs and for seasons and for days and years, 15 and let them be lights in the dome of the sky to give light upon the earth." And it was so. 16 God made the two great lights--the greater light to rule the day and the lesser light to rule the night--and the stars. 17 God set them in the dome of the sky to give light upon the earth, 18 to rule over the day and over the night, and to separate the light from the darkness. And God saw that it was good. 19 And there was evening and there was morning, the fourth day. 
20 And God said, "Let the waters bring forth swarms of living creatures, and let birds fly above the earth across the dome of the sky." 21 So God created the great sea monsters and every living creature that moves, of every kind, with which the waters swarm, and every winged bird of every kind. And God saw that it was good. 22 God blessed them, saying, "Be fruitful and multiply and fill the waters in the seas, and let birds multiply on the earth." 23 And there was evening and there was morning, the fifth day. 
24 And God said, "Let the earth bring forth living creatures of every kind: cattle and creeping things and wild animals of the earth of every kind." And it was so. 25 God made the wild animals of the earth of every kind, and the cattle of every kind, and everything that creeps upon the ground of every kind. And God saw that it was good. 
26 Then God said, "Let us make humankind in our image, according to our likeness; and let them have dominion over the fish of the sea, and over the birds of the air, and over the cattle, and over all the wild animals of the earth, and over every creeping thing that creeps upon the earth." 
27 So God created humankind in his image, 
in the image of God he created them; 
male and female he created them. 
28 God blessed them, and God said to them, "Be fruitful and multiply, and fill the earth and subdue it; and have dominion over the fish of the sea and over the birds of the air and over every living thing that moves upon the earth." 29 God said, "See, I have given you every plant yielding seed that is upon the face of all the earth, and every tree with seed in its fruit; you shall have them for food. 30 And to every beast of the earth, and to every bird of the air, and to everything that creeps on the earth, everything that has the breath of life, I have given every green plant for food." And it was so. 31 God saw everything that he had made, and indeed, it was very good. And there was evening and there was morning, the sixth day. 2:1 Thus the heavens and the earth were finished, and all their multitude. 2 And on the seventh day God finished the work that he had done, and he rested on the seventh day from all the work that he had done. 3 So God blessed the seventh day and hallowed it, because on it God rested from all the work that he had done in creation. 
4 These are the generations of the heavens and the earth when they were created. 

Isaiah 40: 12 - 17, 27 - 31 (C of E) 

Isai 40:12 (NRSV) Who has measured the waters in the hollow of his hand 
and marked off the heavens with a span, 
enclosed the dust of the earth in a measure, 
and weighed the mountains in scales 
and the hills in a balance? 
13 Who has directed the spirit of the LORD, 
or as his counselor has instructed him? 
14 Whom did he consult for his enlightenment, 
and who taught him the path of justice? 
Who taught him knowledge, 
and showed him the way of understanding? 
15 Even the nations are like a drop from a bucket, 
and are accounted as dust on the scales; 
see, he takes up the isles like fine dust. 
16 Lebanon would not provide fuel enough, 
nor are its animals enough for a burnt offering. 
17 All the nations are as nothing before him; 
they are accounted by him as less than nothing and emptiness. 

27 Why do you say, O Jacob, 
and speak, O Israel, 
"My way is hidden from the LORD, 
and my right is disregarded by my God"? 
28 Have you not known? Have you not heard? 
The LORD is the everlasting God, 
the Creator of the ends of the earth. 
He does not faint or grow weary; 
his understanding is unsearchable. 
29 He gives power to the faint, 
and strengthens the powerless. 
30 Even youths will faint and be weary, 
and the young will fall exhausted; 
31 but those who wait for the LORD shall renew their strength, 
they shall mount up with wings like eagles, 
they shall run and not be weary, 
they shall walk and not faint. 

Exodus 34: 4b - 6, 8 - 9   (Roman Catholic) 

Exod 34:4 (NRSV) [Moses] rose early in the morning and went up on Mount Sinai, as the LORD had commanded him, and took in his hand the two tablets of stone. 5 The LORD descended in the cloud and stood with him there, and proclaimed the name, "The LORD." 6 The LORD passed before him, and proclaimed, 
"The LORD, the LORD, 
a God merciful and gracious, 
slow to anger, 
and abounding in steadfast love and faithfulness, 

8 And Moses quickly bowed his head toward the earth, and worshiped. 9 He said, "If now I have found favor in your sight, O Lord, I pray, let the Lord go with us. Although this is a stiff-necked people, pardon our iniquity and our sin, and take us for your inheritance." 

PSALM 8   (RCL) 

Psal 8:1 (NRSV) O LORD, our Sovereign, 
how majestic is your name in all the earth! 
You have set your glory above the heavens. 
2 Out of the mouths of babes and infants 
you have founded a bulwark because of your foes, 
to silence the enemy and the avenger. 
3 When I look at your heavens, the work of your fingers, 
the moon and the stars that you have established; 
4 what are human beings that you are mindful of them, 
mortals that you care for them? 
5 Yet you have made them a little lower than God, 
and crowned them with glory and honor. 
6 You have given them dominion over the works of your hands; 
you have put all things under their feet, 
7 all sheep and oxen, 
and also the beasts of the field, 
8 the birds of the air, and the fish of the sea, 
whatever passes along the paths of the seas. 
9 O LORD, our Sovereign, 
how majestic is your name in all the earth! 

8   Domine, Dominus noster    (ECUSA BCP)
 
1  	O Lord our Governor, *
 	how exalted is your Name in all the world!
 
2  	Out of the mouths of infants and children *
 	your majesty is praised above the heavens.
 
3  	You have set up a stronghold against your adversaries, *
 	to quell the enemy and the avenger.
 
4  	When I consider your heavens, the work of your fingers, *
 	the moon and the stars you have set in their courses,
 
5  	What is man that you should be mindful of him? *
 	the son of man that you should seek him out?
 
6  	You have made him but little lower than the angels; *
 	you adorn him with glory and honor;
 
7  	You give him mastery over the works of your hands; *
 	you put all things under his feet:
 
8  	All sheep and oxen, *
 	even the wild beasts of the field,
 
9  	The birds of the air, the fish of the sea, *
 	and whatsoever walks in the paths of the sea.
 
10 	O Lord our Governor, *
 	how exalted is your Name in all the world!

(Canticle) 13   A Song of Praise    Benedictus es, Domine   (ECUSA BCP; Roman Catholic, alt. for ECUSA)

	  Song of the Three Young Men, 29-34

Glory to you, Lord God of our fathers; *
   you are worthy of praise; glory to you. 
Glory to you for the radiance of your holy Name; *
   we will praise you and highly exalt you for ever. 

Glory to you in the splendor of your temple; *
   on the throne of your majesty, glory to you. 
Glory to you, seated between the Cherubim; *
   we will praise you and highly exalt you for ever. 

Glory to you, beholding the depths; *
   in the high vault of heaven, glory to you. 
Glory to you, Father, Son, and Holy Spirit; *
   we will praise you and highly exalt you for ever.

2Cor 13:11 (NRSV)  Finally, brothers and sisters, farewell. Put things in order, listen to my appeal, agree with one another, live in peace; and the God of love and peace will be with you. 12 Greet one another with a holy kiss. All the saints greet you. 
13 The grace of the Lord Jesus Christ, the love of God, and the communion of the Holy Spirit be with all of you.

GOSPEL: Matthew 28: 16 - 20 (RCL) 

Matt 28:16 (NRSV) Now the eleven disciples went to Galilee, to the mountain to which Jesus had directed them. 17 When they saw him, they worshiped him; but some doubted. 18 And Jesus came and said to them, "All authority in heaven and on earth has been given to me. 19 Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 and teaching them to obey everything that I have commanded you. And remember, I am with you always, to the end of the age." 

John 3: 16 - 18 (Roman Catholic) 

John 3:16 (NRSV) "For God so loved the world that he gave his only Son, so that everyone who believes in him may not perish but may have eternal life. 
17 "Indeed, God did not send the Son into the world to condemn the world, but in order that the world might be saved through him. 18 Those who believe in him are not condemned; but those who do not believe are condemned already, because they have not believed in the name of the only Son of God.
