The Works of William Chillingworth Containing His Book, Entitl'd "The Religion of Protestants a Safe Way to Salvation"

The Religion of Protestants a Safe Way to Salvation was originally published in 1638, written by the English churchman William Chillingworth. It emerged during a period of intense theological turbulence in 17th-century England, serving as a landmark defense of rationalism and the idea that the Bible, rather than church tradition or ecclesiastical authority, should be the ultimate foundation of Christian faith. The work was famously composed in response to the Jesuit Edward Knott, who had challenged the logic of Chillingworth's conversion to Anglicanism.

The design of collected editions of Chillingworth's works often emphasized the scholarly gravity of the text, typically featuring austere, folio-sized bindings intended for private libraries or theological colleges. These volumes were widely respected by contemporaries for their methodical, polemical clarity, and they remained standard reference works for Anglican divinity for over a century. The focus was consistently on typographic legibility and the formal structure of the arguments, reflecting the intellectual rigor that established Chillingworth as a key precursor to the Enlightenment emphasis on individual conscience.
