Amendment I (Religion)
Document 16
James Madison to William Bradford
24 Jan. 1774Papers 1:106I want again to breathe your free Air. I expect it will mend my Constitution & confirm my principles. I have indeed as good an Atmosphere at home as the Climate will allow: but have nothing to brag of as to the State and Liberty of my Country. Poverty and Luxury prevail among all sorts: Pride ignorance and Knavery among the Priesthood and Vice and Wickedness among the Laity. This is bad enough But It is not the worst I have to tell you. That diabolical Hell conceived principle of persecution rages among some and to their eternal Infamy the Clergy can furnish their Quota of Imps for such business. This vexes me the most of any thing whatever. There are at this [time?] in the adjacent County not less than 5 or 6 well meaning men in close [Gaol] for publishing their religious Sentiments which in the main are very orthodox. I have neither patience to hear talk or think of any thing relative to this matter, for I have squabbled and scolded abused and ridiculed so long about it, [to so lit]tle purpose that I am without common patience. So I [leave you] to pity me and pray for Liberty of Conscience [to revive among us.]
