This seventh volume includes three treatises that strike a helpful balance of emphases on theology, history, and practice.

A Reformed Catholic exists as a systematic, theological presentation of Perkins’s Reformed soteriology in contrast with the Church of Rome.

Perkins’s Problem of the Forged Catholicism is an exercise in historical theology, proving from the primary source documents of church history that the Roman Catholicism articulated at Trent is not supported by the first twelve hundred years of the church’s witness.

A Warning Against Idolatry handles worship practices–including liturgies, ceremonies, customs, and rites–concluding that all the externals of worship must be regulated by Scripture in the strictest sense.

Taken as a whole, Perkins’s polemical work against the Church of Rome draws a clear dividing line between Roman Catholicism and the Reformed tradition.
