"The Puritans were excellent covenant theologians. They lived covenant theology, covenanting themselves, their families, their churches, and their nations to God. Yet they did not fall into the error of hyper-covenantalism, in which the covenant of grace becomes a substitute for personal conversion. They promoted a comprehensive worldview, a total Christian philosophy, a holistic approach of bringing the whole gospel to bear on all of life, striving to bring every action in conformity with Christ, so that believers would mature and grow in faith. The Puritans wrote on practical subjects such as how to pray, how to develop genuine piety, how to conduct family worship, and how to raise children for Christ. In short, they taught how to develop a 'rational, resolute, passionate piety [that is] conscientious without becoming obsessive, law-oriented without lapsing into legalism, and expressive of Christian liberty without any shameful lurches into license.' Doctrinally, Puritanism was a kind of vigorous Calvinism; experientially, it was warm and contagious; evangelistically, it was aggressive, yet tender; ecclesiastically, it was theocentric and worshipful; politically, it aimed to be scriptural, balanced, and bound by conscience before God in the relationships of king, Parliament, and subjects; culturally, it had lasting impact throughout succeeding generations and centuries until today." - Dr. Joel Beeke, "Why You Should Read the Puritans."
