Puritans
Calvinism

Puritanism broadly refers to a diverse religious reform movement in Britain committed to the Continental Reformed tradition. While Puritans did not agree on all doctrinal points, most shared similar views on the nature of God, human sinfulness, and the relationship between God and mankind. They believed that all of their beliefs should be based on the Bible, which they considered to be divinely inspired.

The concept of covenant was extremely important to Puritans, and covenant theology was central to their beliefs. With roots in the writings of Reformed theologians John Calvin and Heinrich Bullinger, covenant theology was further developed by Puritan theologians Dudley Fenner, William Perkins, John Preston, Richard Sibbes, William Ames and, most fully by Ames's Dutch student, Johannes Cocceius. Covenant theology asserts that when God created Adam and Eve he promised them eternal life in return for perfect obedience; this promise was termed the covenant of works. After the fall of man, human nature was corrupted by original sin and unable to fulfill the covenant of works, since each person inevitably violated God's law as expressed in the Ten Commandments. As sinners, every person deserved damnation.

Puritans shared with other Calvinists a belief in double predestination, that some people (the elect) were destined by God to receive grace and salvation while others were destined for Hell. No one, however, could merit salvation. According to covenant theology, Christ's sacrifice on the cross made possible the covenant of grace, by which those selected by God could be saved. Puritans believed in unconditional election and irresistible grace —God's grace was given freely without condition to the elect and could not be refused.
