Puritanism from within...

This post is for those of you who have access to Early English Books Online (EEBO). Reading The Culture of English Puritanism (Durston and Eales, eds.) reminded me of a few resources for defining/describing puritanism. These three sources were written from within the puritan 'camp' during the seventeenth century. If you have access to EEBO, they may be worth a read.

The Plea of the Innocent (1602) by Josias Nichols
Nichols was a puritan minister in Kent during the reign of Elizabeth.

A Discourse Concerning Puritans (1641) by Henry Parker
This is useful (as Durston and Eales point out) because Parker identifies four streams that puritans themselves recognized within Puritanism.

The Character of an Old English Puritane or Non-Conformist (1646) by John Geree
Geree provides a glimpse of how puritans viewed themselves during the
tumultuous Civil War period.
