Definition and Significance of the New Testament

The term "New Testament" refers to the second major division of the Christian Bible, comprising 27 books that primarily narrate the life and teachings of Jesus Christ, the establishment of the early Christian church, and apostolic instruction [5]. The name itself derives from the Greek word diatheke, which is translated as both "testament" and "covenant" [3, 4]. While the King James Version frequently renders diatheke as "testament," the Revised Version consistently translates it as "covenant" [4]. This distinction is significant because the "New Testament" is understood as the "New Covenant," contrasting with the "old covenant of works" which it supersedes [1].

This concept of a new covenant is rooted in biblical passages such as Luke 22:20, where Jesus speaks of "this cup is the new covenant in my blood" [1]. The Epistle to the Hebrews further emphasizes this, stating, "In that he saith a new Testament, he hath abrogate the olde: nowe that which is disanulled and waxed olde, is ready to vanish away" (Hebrews 8:13, Geneva 1599) [13]. Matthew Henry, a Nonconformist commentator, explains that the gospel is considered the "new and last will and testament of Christ," highlighting the necessity of Christ's blood to validate and make this testament effective [15]. He also notes that while solemn transactions between God and humanity are sometimes called a covenant, here it is a testament [15]. John Gill, a Baptist commentator, elaborates that the covenant of grace functions as a testament or will for God's people, established by Christ's death [19].

The New Testament, as a collection of sacred writings, is considered by Christians to be divinely inspired and an infallible record of God's revealed will [2]. It is seen as the "gospel of Jesus Christ the Son of God," bringing "glad tidings" [14]. The Old Testament prophets foretold the coming of Christ, and the New Testament fulfills these prophecies, providing a "more strong and convincing" proof of the truth of the gospel [16]. The apostle Paul, in 2 Corinthians 3:6, contrasts the Old Testament (the law of Moses) with the New Testament (the gospel of Jesus Christ), emphasizing that ministers of the New Testament are ministers "not merely of the letter" but of the spirit [18].

The New Testament contains accounts of various individuals who lived during its historical period, such as Festus, Alphaeus, Crescens, Jambres, Hymenaeus, and Theudas [7, 8, 9, 10, 11, 12]. While it lays down general principles for good government, it does not provide a specific code of laws for the punishment of offenders, focusing instead on the eternal distinction between right and wrong [6]. The overarching theme is the covenant of grace, which is described as "ever fresh, flourishing, and excellent," and dispensed "in a more clear, spiritual, extensive, and powerful manner than of old" under the gospel [1]. The New Testament, therefore, represents the culmination of God's redemptive plan, offering forgiveness for sins and an eternal inheritance through Christ's sacrifice [17].

  1. Easton's Bible Dictionary “Easton's Bible Dictionary: New Testament — (Luke 22:20), rather "New Covenant," in contrast to the old covenant of works, which is superseded. "The covenant of grace is called new; it succeeds to the old broken covenant of works. It is ever fresh, flourishing, and excellent; and under the gospel it is dispensed in a more clear, spiritual, extensive, and powerful manner than of old" (Brown of Haddington). Hence is derived the name given to the latter portion of the Bible. (See [438]TESTAMENT.)”

Easton's Bible Dictionary “Easton's Bible Dictionary: Scripture — Invariably in the New Testament denotes that definite collection of sacred books, regarded as given by inspiration of God, which we usually call the Old Testament (2 Tim. 3:15, 16; John 20:9; Gal. 3:22; 2 Pet. 1:20). It was God's purpose thus to perpetuate his revealed will. From time to time he raised up men to commit to writing in an infallible record the revelation he gave. The "Scripture," or collection of sacred writings, was thus enlarged from time to time as God saw necessary. We have now a completed "Scripture," consisting of the Old and New Testa”

The Vulgate translates incorrectly by testamentum, whence the names "Old" and "New Testament," by which we now designate the two sections into which the Bible is divided. (See [629]BIBLE.)”

Easton's Bible Dictionary “Easton's Bible Dictionary: Punishment — The New Testament lays down the general principles of good government, but contains no code of laws for the punishment of offenders. Punishment proceeds on the principle that there is an eternal distinction between right and wrong, and that this distinction must be maintained for its own sake. It is not primarily intended for the reformation of criminals, nor for the purpose of deterring others from sin. These results may be gained, but crime in itself demands punishment.
