The Protestants and Roman Catholics were divided on the role of Scripture in a believer’s life. In this massive work, Whitaker argues the Protestant position. He deals with the number of canonical books, the authority of Scripture, the perspicuity of Scripture, the proper interpretation of Scripture, and the perfection of Scripture.

Author  William Whitaker (1547-1595) (sometimes spelled "Whitacre") attended Trinity College and received his Doctorate of Divinity degree fro Oxford. A master debater on the role of Scripture in the church, these writings present the Biblical context of the doctrine of Sola Scriptura.
