The declaration of independence and the constitution, including state constitutions, are secular documents, but in their psychological impact one might regard them as sacred text to which an authority adheres, thou shalt not change scripture, you can only interpret it. This is because, in my opinion, they have been inextricably linked with a definition of independence and self reliance that makes up the core of American subjectivity, how they define themselves. Reformers battle against a perception of committing heresy.
