"The light of the Menorah reminds us that the sacredness of a nation is in its spirit and that preserving that spirit is an eternal struggle against the conquerors of land and the tyrants of souls."
Americans of early generations were taught about the "necessity of preserving that spirit" in their homes and schools. For instance, early generations (prior to "progressive" changes to textbooks) might have been familiar with the following reasons for annual "celebration" of their spirit of freedom:
John Adams, on July 2, 1776, after the long struggle for independence, and when the Continental Congress had adopted the Declaration of Independence, wrote to wife, Abigail:The second day of July, 1776, will be the most memorable epocha in the history of America. I am apt to believe it will be celebrated by succeeding generations as the great anniversary festival. It ought to be commemorated as the day of deliverance, by solemn acts of devotion to God Almighty. It ought to be solemnized with pomp and parade, with shows, games, sports, guns, bells, bonfires, and illuminations, from one end of this continent to the other, from this time forward forevermore.
You will think me transported with enthusiasm, but I am not. I am well aware of the toil and blood and treasure that it will cost us to maintain this Declaration and support and defend these states. Yet, through all the gloom, I can see the rays of ravishing light and glory. I can see that the end is more than worth all the means. And that posterity will triumph in that day’s transaction, even although we should rue it, which I trust in God we shall not…
It may be the will of Heaven that America will suffer calamities still more wasting, and distress yet more dreadful. If this is to be the case, it will have this good effect at least. It will inspire us with many virtues which we have not, and correct many errors, follies and vices which threaten to disturb, dishonor and destroy us. The furnace of affliction produces refinement, in States as well as individuals...But I must submit all my hopes and fears to an overruling Providence, in which, unfashionable as the faith may be, I firmly believe. - John Adams, Letter to Abigal Adams, July 2, 1776)
Or, they might remember the great "celebration" in New York City in April, 1839, on the 50th Anniversary under their Constitution, where John Quincy Adams was invited to deliver the "Jubilee Address," outlining the ideas of that Declaration of Independence and how they became the foundation of their Constitution.
John Quincy Adams concluded that Address with these words:
"Fellow-citizens, the ark of your covenant is the Declaration of independence. Your Mount Ebal, is the confederacy of separate state sovereignties, and your Mount Gerizim is the Constitution of the United States. In that scene of tremendous and awful solemnity, narrated in the Holy Scriptures, there is not a curse pronounced against the people, upon Mount Ebal, not a blessing promised them upon Mount Gerizim, which your posterity may not suffer or enjoy, from your and their adherence to, or departure from, the principles of the Declaration of Independence, practically interwoven in the Constitution of the United States. Lay up these principles, then, in your hearts, and in your souls - bind them for signs upon your hands, that they may be as frontlets between your eyes - teach them to your children, speaking of them when sitting in your houses, when walking by the way, when lying down and when rising up - write them upon the doorplates of your houses, and upon your gates - cling to them as to the issues of life - adhere to them as to the cords of your eternal salvation. So may your children's children at the next return of this day of jubilee, after a full century of experience under your national Constitution, celebrate it again in the full enjoyment of all the blessings recognized by you in the commemoration of this day, and of all the blessings promised to the children of Israel upon Mount Gerizim, as the reward of obedience to the law of God." - John Quincy Adams, "Jubilee," April 1839
This proves what Obama said, that Islam was woven into the fabric of America from the very beginning. /S
