A Prayer for Our Nation

Our Lady of the Immaculate Conception, Patroness of our Nation,
today we humbly turn to you for your intercession and guidance as a Nation.
Dear Mother may your example guide us today, that we as a Nation may
through the grace of God the Father experience healing, unity, and peace.
May our Nation always be a beacon of hope, liberty, justice, and peace
to the world.
