The phrase good and necessary consequence was used more commonly several centuries ago to express the idea which we would place today under the general heading of logic; that is, to reason validly by logical deduction or better, deductive reasoning.

Even more particularly, it would be understood in terms of term logic, also known as traditional logic, or as many today would also consider it to be part of formal logic, which deals with the form (or logical form) of arguments as to which are valid or invalid.

In this context, we may better understand the word "good" in the phrase "good and necessary consequence" more technically as intending a "valid argument form".

One of the best recoqnised articulations of the authoritative use of good and necessary consequence to make deductions from Scripture can be readily found in probably the most famous of Protestant Confessions of faith, the Westminster Confession of Faith (1646), Chapter 1, sec. 6, as well as in many others, including the Heidelberg Catechism, the Belgic Confession, and the London Baptist Confession (1677/1689).
