One of them saw to it that an American Edition of the Holy Bible be printed from the Congressional Printing Press, and a copy of the original American Edition of the Holy Bible resides in the halls of Congress to this very day.
There also is, located next to the main entrance to the Senate, a small chapel where Congress members and their staff can enter to meditate, pray, and hold Bible study during their free time.
The chapel is not open to the public, but it's clearly distinguishable by it's stainglass window of of a portrait of George Washington genuflecting in prayer.
I'm stuck by the core Christianity the American founders showed on their public profession of Christianity. In Britain itself even today public expressions of religion are confined to a particular sect of Christianity (Presbyterianism for Scotland and Anglicanism for England, for instance). British people will feel uncomfortable if they see public ceremonies are interwoven with Baptist teachings, for instance.
In Britain and even New Zealand you feel it is like "Anglicanism above Christianity" while the opposite is true for the United States.
