...I would suggest that such practices as the designation of "In God We Trust" as our national motto, or the references to God contained in the Pledge of Allegiance to the flag can best be understood, in Dean Rostow's apt phrase, as a form a "ceremonial deism," protected from Establishment Clause scrutiny chiefly because they have lost through rote repetition any significant religious content.

There are no ''de minimis'' violations of the Constitution – no constitutional harms so slight that the courts are obliged to ignore them. Given the values that the Establishment Clause was meant to serve, however, I believe that government can, in a discrete category of cases, acknowledge or refer to the divine without offending the Constitution. This category of "ceremonial deism" most clearly encompasses such things as the national motto ("In God We Trust"), religious references in traditional patriotic songs such as "The Star-Spangled Banner", and the words with which the Marshal of this Court opens each of its sessions ("God save the United States and this honorable Court"). These references are not minor trespasses upon the Establishment Clause to which I turn a blind eye. Instead, their history, character, and context prevent them from being constitutional violations at all. [''emphasis added, citations omitted'']
