Biblical Concept: Communal Thanksgiving

There are at least 5 Psalms that can be classified as Psalms of communal thanksgiving.  These are: Psalms 75, 95, 100, 107, and 126.  The New Testament also encourages communal thanksgiving.  For example:

NAS Colossians 3:15 And let the peace of Christ rule in your hearts, to which indeed you were called in one body; and be thankful. 16 Let the word of Christ richly dwell within you, with all wisdom teaching and admonishing one another with psalms and hymns and spiritual songs, singing with thankfulness in your hearts to God.
The United States of America has a rich history of communal thanksgiving toward the God of the Bible.  William Bradford, governor of the Plymouth Colony, declared November 29th 1623 a day of communal thanksgiving:
now I, your magistrate, do proclaim that all ye Pilgrims, with your wives and ye little ones, do gather at ye meeting house . . . there to listen to ye pastor and render thanksgiving to ye Almighty God for all His blessings.*
The Continental Congress, on November 1st 1777,  in response to military victory at Saratoga, issued the First National Proclamation of Thanksgiving:
Forasmuch as it is the indispensable duty of all men to adore the
superintending Providence of Almighty God; to acknowledge with gratitude
their obligation to Him for benefits received and to implore such further
blessing as they stand in need of; and it having pleased Him in His abundant mercy not only to continue to us the innumerable bounties of His common smile upon us as in the prosecution of a just and necessary war for the defense and establishment of our unalienable rights and liberties...
President George Washington, on October 3rd 1789,  declared a National Day of Thanksgiving:
that we then may all unite unto him our sincere and humble thanks for His
kind care and protection of the people of this country previous to their
becoming a nation; for the signal and manifold mercies and the favorable
interpositions of His providence in the course and conclusion of the late war;
On October 3rd 1863, the Congress of the United States of America passed an Act of Congress, as proclaimed by President Abraham Lincoln, an annual National  Day of  Thanksgiving:
I do, therefore, invite my fellow citizens in every part of the United
set apart and observe the last Thursday of November next as a day of
Thanksgiving and Praise to our beneficent Father who dwelleth in the
heavens...[it is] announced in the Holy Scriptures and proven by all history,
that those nations are blessed whose God is the Lord...It has seemed to me fit and proper that God should be solemnly, reverently and gratefully
acknowledged, as with one heart and one voice, by the whole American
2 Timothy 2:1 says: “First of all, then, I urge that entreaties and prayers, petitions and  thanksgivings, be made on behalf of all men” (NAS).  Let us give thanks for the founders of our great nation, who had the vision to be men of communal thanksgiving.  Amen.
