Of the Holy Trinity

The Collect

Almighty God, you have revealed to your Church your eternal Being of glorious majesty and perfect love as one God in Trinity of Persons: Give us grace to continue steadfast in the confession of this faith, and constant in our worship of you, Father, Son, and Holy Spirit; for you live and reign, one God, now and for ever. Amen.

Old Testament

Exodus 3:11-15

Moses said to God, "Who am I that I should go to Pharaoh, and bring the Israelites out of Egypt?" He said, "I will be with you; and this shall be the sign for you that it is I who sent you: when you have brought the people out of Egypt, you shall worship God on this mountain."

But Moses said to God, "If I come to the Israelites and say to them, 'The God of your ancestors has sent me to you', and they ask me, 'What is his name?' what shall I say to them?" God said to Moses, "I am who I am." He said further, "Thus you shall say to the Israelites, 'I am has sent me to you.' " God also said to Moses, "Thus you shall say to the Israelites, 'The Lord, the God of your ancestors, the God of Abraham, the God of Isaac, and the God of Jacob, has sent me to you':

This is my name for ever,
and this my title for all generations."

The Psalm

Psalm 29

Afferte Domino

1 Ascribe to the Lord, you gods, *
ascribe to the Lord glory and strength.

2 Ascribe to the Lord the glory due his Name; *
worship the Lord in the beauty of holiness.

3 The voice of the Lord is upon the waters;
the God of glory thunders; *
the Lord is upon the mighty waters.

4 The voice of the Lord is a powerful voice; *
the voice of the Lord is a voice of splendor.

5 The voice of the Lord breaks the cedar trees; *
the Lord breaks the cedars of Lebanon;

6 He makes Lebanon skip like a calf, *
and Mount Hermon like a young wild ox.

7 The voice of the Lord splits the flames of fire;
the voice of the Lord shakes the wilderness; *
the Lord shakes the wilderness of Kadesh.

8 The voice of the Lord makes the oak trees writhe *
and strips the forests bare.

9 And in the temple of the Lord *
all are crying, "Glory!"

10 The Lord sits enthroned above the flood; *
the Lord sits enthroned as King for evermore.

11 The Lord shall give strength to his people; *
the Lord shall give his people the blessing of peace.

The New Testament

Romans 11:33-36

O the depth of the riches and wisdom and knowledge of God! How unsearchable are his judgements and how inscrutable his ways!

"For who has known the mind of the Lord?
Or who has been his counsellor?"

"Or who has given a gift to him,
to receive a gift in return?"

For from him and through him and to him are all things. To him be the glory for ever. Amen.

The Gospel

Matthew 28:18-20

Jesus came and said to the eleven disciples, "All authority in heaven and on earth has been given to me. 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, and teaching them to obey everything that I have commanded you. And remember, I am with you always, to the end of the age."
