Commontide
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.

Preface of Trinity Sunday
Who, with your co-eternal Son and Holy Spirit, are one God, one Lord, in Trinity of Persons and in Unity of Substance. For that which we believe of your glory, O Father, we believe the same of your Son, and of the Holy Spirit, without any difference or inequality.
