The puritans

Were English Reformers of the sixteenth and seventeenth centuries. They were frustrated by the slow progress of the Reformation in the Anglican Church. They left a legacy of theological writing that is unsurpassed in church history. Their doctrine tended to be Calvinistic and Presbyterian, and their finest writings were both polemic and devotional treatments of theology.
