Prayers for National Life
19. For the President of the United States and all in Civil Authority
O Lord our Governor, whose glory is in all the world: We commend this nation to thy merciful care, that, being guided by thy Providence, we may dwell secure in thy peace. Grant to the President of the United States, the Governor of this State (or Commonwealth), and to all in authority, wisdom and strength to know and to do thy will. Fill them with the love of truth and righteousness, and make them ever mindful of their calling to serve this people in thy fear; through Jesus Christ our Lord, who liveth and reigneth with thee and the Holy Spirit, one God, world without end. Amen.
Prayers originally composed in traditional idiom have not been modernized; but, except in certain classical prayers which do not lend themselves to modernization, pronouns and verbs have been put in italics to assist in rendering them into contemporary speech.
