A statement rejecting formal sectarian organizations and claims, this has been cited to a quotation in Picturesque America by William Cullen Bryant, p. 502, first published in 1872. However, while presented as characterizing the views Williams held, and thus fairly characterizable as about Williams, that book published nearly two centuries after his death does not provide further attribution of the quote to any work published by Williams in his lifetime.

Men's consciences ought in no sort to be violated, urged, or constrained.
Opinions offensive are of two sorts: some savoring of impiety, and some of incivility.
