Though the word trinity is not found in the scriptures, Sunday’s second reading includes the apostolic greeting that begins the liturgy: The grace of our Lord Jesus Christ, the love of God, and the communion of the Holy Spirit be with you all. In the gospel Jesus sends his disciples forth to baptize in the name of the Father, and the Son, and the Holy Spirit. More than a doctrine, the Trinity expresses the heart of our faith: we have experienced the God of creation made known in Jesus Christ and with us always through the Holy Spirit. We celebrate the mystery of the Holy Trinity in word and sacrament, as we profess the creed, and as we are sent into the world to bear witness to our faith.
Prayer of the Day
Almighty Creator and ever-living God: we worship your glory, eternal Three-in-One, and we praise your power, majestic One-in-Three. Keep us steadfast in this faith, defend us in all adversity, and bring us at last into your presence, where you live in endless joy and love, Father, Son, and Holy Spirit, one God, now and forever. Amen.
Readings and Psalm
2 Corinthians 13:11-13
First Reading: Genesis 1:1–2:4a
1In the beginning when God created the heavens and the earth, 2the 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. 3Then God said, “Let there be light”; and there was light. 4And God saw that the light was good; and God separated the light from the darkness. 5God called the light Day, and the darkness he called Night. And there was evening and there was morning, the first day.
6And God said, “Let there be a dome in the midst of the waters, and let it separate the waters from the waters.” 7So 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. 8God called the dome Sky. And there was evening and there was morning, the second day.
9And God said, “Let the waters under the sky be gathered together into one place, and let the dry land appear.” And it was so. 10God called the dry land Earth, and the waters that were gathered together he called Seas. And God saw that it was good. 11Then 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. 12The 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. 13And there was evening and there was morning, the third day.
14And 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, 15and let them be lights in the dome of the sky to give light upon the earth.” And it was so. 16God made the two great lights—the greater light to rule the day and the lesser light to rule the night—and the stars. 17God set them in the dome of the sky to give light upon the earth, 18to rule over the day and over the night, and to separate the light from the darkness. And God saw that it was good. 19And there was evening and there was morning, the fourth day.
20And God said, “Let the waters bring forth swarms of living creatures, and let birds fly above the earth across the dome of the sky.” 21So 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. 22God blessed them, saying, “Be fruitful and multiply and fill the waters in the seas, and let birds multiply on the earth.” 23And there was evening and there was morning, the fifth day.
24And 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. 25God 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.
26Then 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.”
27So God created humankind in his image,
in the image of God he created them;
male and female he created them.
28God 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.” 29God 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. 30And 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. 31God saw everything that he had made, and indeed, it was very good. And there was evening and there was morning, the sixth day.
2:1Thus the heavens and the earth were finished, and all their multitude. 2And 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. 3So God blessed the seventh day and hallowed it, because on it God rested from all the work that he had done in creation.
4aThese are the generations of the heavens and the earth when they were created.
Psalm: Psalm 8
1O Lord our Lord,
how majestic is your name in all the earth!—
2you whose glory is chanted above the heavens out of the mouths of infants and children;
you have set up a fortress against your enemies, to silence the foe and avenger.
3When I consider your heavens, the work of your fingers,
the moon and the stars you have set in their courses,
4what are mere mortals that you should be mindful of them,
human beings that you should care for them?
5Yet you have made them little less than divine;
with glory and honor you crown them.
6You have made them rule over the works of your hands;
you have put all things under their feet:
7all flocks and cattle,
even the wild beasts of the field,
8the birds of the air, the fish of the sea,
and whatever passes along the paths of the sea.
9O Lord our Lord,
how majestic is your name in all the earth!
Second Reading: 2 Corinthians 13:11-13
[Paul writes:] 11Finally, 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. 12Greet one another with a holy kiss. All the saints greet you.
13The 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
16Now the eleven disciples went to Galilee, to the mountain to which Jesus had directed them. 17When they saw him, they worshiped him; but some doubted. 18And Jesus came and said to them, “All authority in heaven and on earth has been given to me. 19Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20and teaching them to obey everything that I have commanded you. And remember, I am with you always, to the end of the age.”
