William Perkins’s A Reformed Catholic answers a question that still divides the church today: what does it actually mean to be “Catholic” in the truest sense? Writing at the height of the Reformation, Perkins argues that the Reformers did not abandon catholic Christianity but recovered it by returning to Scripture, the gospel, and the faith of the early church.
