[T]he founding fathers didn’t create the ceremonies and slogans that come to mind when we consider whether this is a Christian nation. Our grandfathers did.And it links strongly to Eisenhower:
Back in the 1930s, business leaders found themselves on the defensive. Their public prestige had plummeted with the Great Crash; their private businesses were under attack by Franklin D. Roosevelt’s New Deal from above and labor from below. To regain the upper hand, corporate leaders fought back on all fronts. They waged a figurative war in statehouses and, occasionally, a literal one in the streets; their campaigns extended from courts of law to the court of public opinion. But nothing worked particularly well until they began an inspired public relations offensive that cast capitalism as the handmaiden of Christianity....
Accordingly, throughout the 1930s and ’40s, corporate leaders marketed a new ideology that combined elements of Christianity with an anti-federal libertarianism.
Uncoupling the language of “freedom under God” from its Christian libertarian roots, Eisenhower erected a bigger revival tent, welcoming Jews and Catholics alongside Protestants, and Democrats as well as Republicans. Rallying the country, he advanced a revolutionary array of new religious ceremonies and slogans.So rather than being white-bread and boring, it turns out that the 50s were quite radical.
The first week of February 1953 set the dizzying pace: On Sunday morning, he was baptized; that night, he broadcast an Oval Office address for the American Legion’s “Back to God” campaign; on Thursday, he appeared with Mr. Vereide at the inaugural National Prayer Breakfast; on Friday, he instituted the first opening prayers at a cabinet meeting.
The rest of Washington consecrated itself, too. The Pentagon, State Department and other executive agencies quickly instituted prayer services of their own. In 1954, Congress added “under God” to the previously secular Pledge of Allegiance. It placed a similar slogan, “In God We Trust,” on postage that year and voted the following year to add it to paper money; in 1956, it became the nation’s official motto.
During these years, Americans were told, time and time again, not just that the country should be a Christian nation, but that it always had been one. They soon came to think of the United States as “one nation under God.” They’ve believed it ever since.
And we're still paying for it.
