Almighty and everlasting God,
you have given us your servants grace,
by the confession of a true faith,
to acknowledge the glory of the eternal Trinity
and in the power of the divine majesty to worship the Unity:
keep us steadfast in this faith,
that we may evermore be defended from all adversities;
through Jesus Christ your Son our Lord,
who is alive and  reigns with you,
in the unity of the Holy Spirit,
one God, now and for ever.
