No purpose of action against religion can be imputed to any legislation, state or national, because this is a religious people. This is historically true. From the discovery of this continent to the present hour, there is a single voice making this affirmation. . . .There is no dissonance in these declarations. There is a universal language pervading them all, having one meaning; they affirm and reaffirm that this is a religious nation. These are not individual sayings, declarations of private persons: they are organic utterances; they speak the voice of the entire people. . . . These, and many other matters which might be noticed, add a volume of unofficial declarations to the mass of organic utterances that this is a Christian nation.
