Almighty and everlasting God, who hast given unto us thy 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: We beseech thee that thou wouldest keep us stedfast in this faith, and evermore defend us from all adversities, who livest and reignest, one God, world without end. Amen.
