a prayer for our country

This was in Magnificat on our Independence Day, but it's just as good for any day -

We pray you, O God of might, wisdom, and justice,

 through whom authority is administered,

 laws are enacted, and judgment decreed,

 assist with your Holy Spirit of counsel and fortitude

 the President of these United States,

 that his administration may be conducted in righteousness,

 and be eminently useful to your people,

 over whom he presides;

 by encouraging due respect for virtue and religion;

by a faithful execution of the laws in justice and mercy;

and by restraining vice and immorality.

Let the light of your divine wisdom direct

the deliberations of Congress,

and shine forth in all the proceedings and laws

framed for our rule and government,

so that they may tend to the preservation of peace,

the promotion of national happiness,

the increase of industry, sobriety, and useful knowledge;

and may perpetuate to us the blessing of equal liberty.

We pray for the governor of this state,

for the members of the assembly,

for all judges, magistrates, and other officers

who are appointed to guard our political welfare, 

that they may be enabled, by your powerful protection,

to discharge the duties of their respective stations with honesty and ability.

We recommend likewise, to your unbounded mercy,

all our fellow citizens throughout the United States,

that we may be blessed in the knowledge

and sanctified in the observance of your most holy law;

that we may be preserved in union,

and in that peace which the world cannot give;

and after enjoying the blessings of this life,

be admitted to those which are eternal.

Grant this, we beseech you, O Lord of mercy,

through Jesus Christ, our Lord and Savior. Amen.

-   Archbishop John Carroll, the first bishop of the United States
