It’s actually amazing on how many times the United States of America has a National Proclamation by the President for National Prayer. Memoria Day is one of those days.
Here is a Prayer for Peace (edited) that I found from Bishop Gregory of the American Carpatho-Russian Orthodox Church:
A Prayer for Peace
Lord Jesus Christ, our God, You said to Your disciples, “Peace I leave with you; my peace I give to you; not as the world gives do I give to you.”
We come before You in humility and ask that Your peace which surpasses all understanding will descend upon all people around the world, especially those currently in conflict and at war.
Increase understanding and forgiveness between nations. Awaken the longing for a peaceful life in all those who are filled with hatred for their neighbor. Extinguish every dispute and banish all temptations to disagreement. Grant wisdom to civil authorities. Free those held captive, protect those in danger, and comfort those who are suffering and displaced. Implant in all of us reverence for You, and confirm us in love for one another.
Make us worthy to join with the angels in chanting: “Glory to God in the highest, and on earth peace, goodwill towards men.” For You are the King of Peace and the Savior of our souls and to You we give glory together with Your eternal Father and Your most holy, gracious and life-giving Spirit, now and ever and forever. Amen.
and the Official Proclamation from the President of the United States, Donald Trump.
In honor and recognition of all of our fallen service members, the Congress, by a joint resolution approved May 11, 1950, as amended (36 U.S.C. 116), has requested the President issue a proclamation calling on the people of the United States to observe each Memorial Day as a day of prayer for permanent peace and designating a period on that day when the people of the United States might unite in prayer. The Congress, by Public Law 106-579, has also designated 3:00 p.m. local time on that day as a time for all Americans to observe, in their own way, the National Moment of Remembrance.
NOW, THEREFORE, I, DONALD J. TRUMP, President of the United States of America, do hereby proclaim Memorial Day, May 29, 2017, as a day of prayer for permanent peace, and I designate the hour beginning in each locality at 11:00 a.m. of that day as a time when people might unite in prayer. I urge the press, radio, television, and all other information media to cooperate in this observance.
I further ask all Americans to observe the National Moment of Remembrance beginning at 3:00 p.m. local time on Memorial Day.
Join me in prayer for permanent peace today.
Love in Christ!
