Ps 8:1-2a, 3-5; Antiphon: Liturgical text, Tobit 12:6
Blessèd be the Holy Trinity and the undivided | Unity.*
             Let us give glory to him because he has shown his mer- | cy to us.
O | Lord, our Lord,*
             how majestic is your name in | all the earth!
You have set your glory above the | heavens.*
             Out of the mouth of babes and infants, you have es- | tablished strength.
When I look at your heavens, the work of your | fingers,*     
             the moon and the stars, which you have | set in place,
what is man that you are mind- | ful of him,*
             and the son of man that you | care for him?
Yet you have made him a little lower than the heavenly | beings*
             and crowned him with glory and | honor.
Glory be to the Father and | to the Son*
             and to the Holy | Spirit;
as it was in the be- | ginning,*
             is now, and will be forever. | Amen.
Blessèd be the Holy Trinity and the undivided | Unity.*
             Let us give glory to him because he has shown his mer- | cy to us.

Collect

Almighty and everlasting God, You have given us grace to acknowledge the glory of the eternal Trinity by the confession of a true faith and to worship the Unity in the power of the Divine Majesty. Keep us steadfast in this faith and defend us from all adversities; for You, O Father, Son, and Holy Spirit, live and reign, one God, now and forever. Amen.

Isaiah 6:1-7

​¹ In the year that King Uzziah died I saw the Lord sitting upon a throne, high and lifted up; and the train of his robe filled the temple. ² Above him stood the seraphim. Each had six wings: with two he covered his face, and with two he covered his feet, and with two he flew. ³ And one called to another and said:
“Holy, holy, holy is the LORD of hosts;
the whole earth is full of his glory!”
⁴ And the foundations of the thresholds shook at the voice of him who called, and the house was filled with smoke. ⁵ And I said: “Woe is me! For I am lost; for I am a man of unclean lips, and I dwell in the midst of a people of unclean lips; for my eyes have seen the King, the LORD of hosts!”
⁶  Then one of the seraphim flew to me, having in his hand a burning coal that he had taken with tongs from the altar. ⁷ And he touched my mouth and said: “Behold, this has touched your lips; your guilt is taken away, and your sin atoned for.”

             and who dwells between the | cherubim.
Blessèd are You, O Lord, in the firmament of | heaven,*

Romans 11:33-36

³³ Oh, the depth of the riches and wisdom and knowledge of God! How unsearchable are his judgments and how inscrutable his ways!
³⁴ “For who has known the mind of the Lord,
or who has been his counselor?”
³⁵ “Or who has given a gift to him
that he might be repaid?”
³⁶ For from him and through him and to him are all things. To him be glory forever. Amen.

John 3:1-15 (16-17)

​¹ Now there was a man of the Pharisees named Nicodemus, a ruler of the Jews. ² This man came to Jesus by night and said to him, “Rabbi, we know that you are a teacher come from God, for no one can do these signs that you do unless God is with him.” ³ Jesus answered him, “Truly, truly, I say to you, unless one is born again he cannot see the kingdom of God.” ⁴ Nicodemus said to him, “How can a man be born when he is old? Can he enter a second time into his mother's womb and be born?” ⁵ Jesus answered, “Truly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God. ⁶ That which is born of the flesh is flesh, and that which is born of the Spirit is spirit. ⁷ Do not marvel that I said to you, ‘You must be born again.’ ⁸ The wind blows where it wishes, and you hear its sound, but you do not know where it comes from or where it goes. So it is with everyone who is born of the Spirit.”
⁹ Nicodemus said to him, “How can these things be?” ¹⁰ Jesus answered him, “Are you the teacher of Israel and yet you do not understand these things? ¹¹ Truly, truly, I say to you, we speak of what we know, and bear witness to what we have seen, but you do not receive our testimony. ¹² If I have told you earthly things and you do not believe, how can you believe if I tell you heavenly things? ¹³ No one has ascended into heaven except he who descended from heaven, the Son of Man. ¹⁴ And as Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up, ¹⁵ that whoever believes in him may have eternal life.
(¹⁶ “For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life. ¹⁷ For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him.)

OR Matthew 28:18-20:

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 teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age.”
