Reformed orthodoxy or Calvinist orthodoxy was an era in the history of Calvinism in the 16th to 18th centuries. Calvinist orthodoxy was paralleled by similar eras in Lutheranism and tridentine Roman Catholicism after the Counter-Reformation. Calvinist scholasticism or Reformed scholasticism was a theological method that gradually developed during the era of Calvinist Orthodoxy.
Theologians used the neo-Aristotelian form of presentation, already popular in academia, in their writings and lectures. They defined the Reformed faith and defended it against the polemics of opposing parties. While the Reformed often used "scholastic" as a term of derision for their Roman Catholic opponents and the content of their theology, most Reformed theologians during this period can properly be called scholastics with respect to the method of theology, though they also used other methods.[1] J. V. Fesko describes scholasticism in this sense as "a method of doing theology that sets out to achieve theological precision through the exegesis of Scripture, an examination of how doctrine has been historically defined throughout church history, and how doctrine is expounded in contemporary debate."[2]
