John F. Kennedy

Let us therefore proclaim our gratitude to Providence for manifold blessings--let us be humbly thankful for inherited ideals--and let us resolve to share those blessings and those ideals with our fellow human beings throughout the world.
On that day, let us gather in sanctuaries dedicated to worship and in homes blessed by family affection to express our gratitude for the glorious gifts of God; and let us earnestly and humbly pray that He will continue to guide and sustain us in the great unfinished tasks of achieving peace, justice, and understanding among all men and nations and of ending misery and suffering wherever they exist
