And who is thus to dogmatize religious opinions for our citizens? Whose foot is to be the measure to which ours are all to be cut or stretched?
Is a priest to be our inquisitor, or shall a layman, simple as ourselves, set up his reason as the rule for what we are to read, and what we must believe?
It is an insult to our citizens to question whether they are rational beings or not, and blasphemy against religion to suppose it cannot stand the test of truth and reason.
Letter to N. G. Dufief, Philadelphia bookseller (1814) who had been prosecuted for selling the book Sur la Création du Monde, un Systême d'Organisation Primitive by M. de Becourt, which Jefferson himself had purchased.
