Solemnity of the Most Holy Trinity.

We acknowledge the Trinity, holy and perfect, to consist of the Father, the Son and the Holy Spirit. In this Trinity there is no intrusion of any alien element or of anything from outside, nor is the Trinity a blend of creative and created being. It is a wholly creative and energising reality, self-consistent and undivided in its active power, for the Father makes all things through the Word and in the Holy Spirit, and in this way the unity of the holy Trinity is preserved. Accordingly, in the Church, one God is preached, one God who is above all things and through all things and in all things. God is above all things as Father, for he is principle and source; he is through all things through the Word; and he is in all things in the Holy Spirit.  When we share in the Spirit, we possess the love of the Father, the grace of the Son and the fellowship of the Spirit himself.

God our Father,
you revealed the great mystery of your godhead to men
when you sent into the world
the Word who is Truth
and the Spirit who makes us holy.
Help us to believe in you and worship you,
as the true faith teaches:
three Persons, eternal in glory,
one God, infinite in majesty.
Through our Lord Jesus Christ, your Son,
who lives and reigns with you in the unity of the Holy Spirit,
one God, for ever and ever.
Amen.
