A Reformed Catholic
William Perkins wrote A Reformed Catholike in 1597 as a direct response to Roman Catholic accusations that Protestant theology was merely innovative heresy lacking historical precedent. Writing during the height of confessional tensions in Elizabethan England, Perkins sought to demonstrate that Reformed doctrine represented not a departure from catholic Christianity but its faithful recovery. The work emerged from his pastoral concern that ordinary English believers needed clear theological grounding to resist Catholic polemical attacks on Protestant legitimacy.
Perkins constructs his argument by systematically showing how Reformed positions on justification, Scripture, sacraments, and church authority align with the teaching of the early church fathers and ecumenical councils. He distinguishes between the "Catholike Church" as the universal body of true believers across history and the "Church of Rome" as a particular institution that had departed from apostolic faith. Through careful patristic citation and theological reasoning, Perkins argues that Protestants are the true catholics because they maintain fidelity to the gospel as taught by Christ, the apostles, and the early church. He demonstrates how Roman additions like papal supremacy, transubstantiation, and justification by works represent innovations that contradict both Scripture and historic Christian consensus.
The treatise became one of the most influential works of Elizabethan apologetics, shaping how English Reformed theologians understood their relationship to church history. Perkins provided a theological framework that allowed Protestants to claim historical legitimacy without rejecting the insights of pre-Reformation Christianity. His method of engaging patristic sources while maintaining commitment to Scripture's supreme authority influenced generations of Reformed scholars.
