Almighty and everlasting God, you have given to us your servants grace, by the confession of a true faith, to acknowledge the glory of the eternal Trinity, and in the power of your divine Majesty to worship the Unity:
Keep us steadfast in this faith and worship, and bring us at last to see you in your one and eternal glory, O Father;
Who with the Son and the Holy Spirit live and reign, one God, for ever and ever.
Amen.Readings from the Revised Common Lectionary:

Michael Bird: What's so Great about the Ascension?
Jesus ascends to heaven so that he can send the Holy Spirit to his followers. Jesus promised the disciples that they would be clothed with “power from on high” (Luke 24:49) and that he would send them the “Advocate” to assist them in their witness and work (John 14:16-17; 14:26; 15:26; 16:7). It is only as the ascended and exalted Lord that could Jesus send the Spirit to them. The sending of the Spirit from the Father and through Jesus is proof that Jesus in his earthly life was the anointed Spirit-bearer and in his exalted state Jesus is the exalted Spirit-giver. The fresh winds of the Holy Spirit are blowing like never before as royal gifts given to his subjects by God’s freshly installed viceroy.Missio Alliance: A New and Powerful Pentecost.

The church, moreover, is but the name of a people who have been formed to worship the Father, the Son, and the Holy Spirit. To worship that God is to live a life described by Jesus in the Sermon on the Mount.
Therefore, Jesus commands his disciples to teach those whom they baptize to obey all that he has commanded. Jesus’s death and resurrection cannot be separated from the way he has taught us to live. The Sermon on the Mount, how we are to serve one another as brothers and sisters, the forgiveness required by our willingness to expose the sin of the church, is salvation. The teaching and the teacher are one. The salvation that Jesus entrusts to his disciples is the gospel of Matthew.
The disciples are to remember that the mission on which Jesus sends them is not one on which they must go alone. He is the resurrected Lord who will always be with those entrusted to witness to him and his work. He was in the beginning, which means that he can promise to be at the end of the age. But the age that he will be present at the end of is the age inaugurated by his birth, ministry, death, and resurrection.May the grace of the Lord Jesus the Anointed [One], the love of God the Father, and the fellowship of the Holy Spirit remain with you all.
On that basis and that basis alone Christians are sent to the world with the message: “Repent, for the kingdom of heaven is present.”
