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;
for you live and reign, one God, for ever and ever.
