Old Testament and New Testament Connections and Relationships

The terms "Old Testament" and "New Testament" refer to the two main divisions of the Christian Bible, reflecting a theological understanding of two distinct covenants established by God [1, 3]. The word "testament" itself is derived from the Greek diatheke, which is more accurately translated as "covenant" [3]. While the Latin Vulgate incorrectly rendered diatheke as testamentum, leading to the common English terms, the underlying concept is that of a divine agreement or covenant [3].

The Old Testament comprises a collection of sacred books regarded as inspired by God, which the New Testament consistently references as "Scripture" [4]. These ancient writings were preserved on materials like skins, rolled into scrolls, similar to modern synagogue rolls [6]. The New Testament frequently quotes from the Old Testament, though not always according to a uniform method, as the Old Testament was not originally divided into chapters and verses as it is today [5]. For instance, Luke refers to Exodus 3:6 as "Moses at the bush," indicating a section rather than a precise verse [5].

The relationship between the Old and New Testaments is primarily understood through the concept of a "new covenant" superseding an "old covenant" [1]. The prophet Jeremiah foretold a new covenant where God would write his instructions on the hearts of his people, contrasting it with the external and legal nature of the old covenant [14]. This new covenant emphasizes a personal, transformative relationship with God [14].

The New Testament presents itself as the "gospel of Jesus Christ," bringing glad tidings and fulfilling the promises of the Messiah [7]. It is considered "new" because it succeeds the "old broken covenant of works" and is dispensed in a clearer, more spiritual, and powerful manner [1]. The author of Hebrews explicitly states that by introducing a "new covenant," God has made the first one old, implying its eventual vanishing [2, 8]. This transition means that both covenants cannot exist simultaneously [8].

Key differences between the two covenants are highlighted in the New Testament:

Paul, in 2 Corinthians, contrasts the "letter" of the Old Testament law with the "spirit" of the New Testament, emphasizing that ministers of the new covenant are not merely ministers of the written word but of the Spirit [10]. The Old Testament also associates fire with the "day of the Lord," a theme that resonates in the New Testament's eschatological descriptions [13]. The death of Christ is central to the new covenant, enabling the "called" to receive the fulfillment of God's promises [9].

"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.)”

  3. Easton's Bible Dictionary “Easton's Bible Dictionary: Testament — Occurs twelve times in the New Testament (Heb. 9:15, etc.) as the rendering of the Gr. diatheke, which is twenty times rendered "covenant" in the Authorized Version, and always so in the Revised Version. 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.)”
  4. 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”

When the New Testament was written, the Old was not divided, as it now is, into chapters and verses, and hence such peculiarities as these: When Luke (20:37) refers to Ex. 3:6, he quotes from "Moses at the bush", i.e., the section containing the record of Moses at the bush. So also Mark (2:26) refers to 1 Sam. 21:1-6, in the words, "in the days of Abiathar;" and Paul (Rom. 11:2) refers to 1 Kings ch. 17-19, in the words, "in Elias", i.e., in the port”

It is the gospel of Jesus Christ the Son of God, Mar 1:1. 1. It is gospel; it is God's word, and is faithful and true; see Rev 19:9; Rev 21:5; Rev 22:6.

From the time of God's mention of a NEW covenant (since God's words are all realities) the first covenant might be regarded as ever dwindling away, until its complete abolition on the actual introduction of the Gospel. Both covenants cannot exist side by side.

  9. Hebrews (Presbyterian) “Jamieson, Fausset & Brown on Hebrews 9:15: for this cause--Because of the all-cleansing power of His blood, this fits Him to be Mediator (Heb 8:6, ensuring to both parties, God and us, the ratification) of the new covenant, which secures both forgiveness for the sins not covered by the former imperfect covenant or testament, and also an eternal inheritance to the called. by means of death--rather, as Greek, "death having taken place." At the moment that His death took place, the necessary effect is, "the called receive the (fulfilment of the) promise" (so Luk 24:49 uses "promise"; Heb 6:15; ”
  10. 2 Corinthians (Nonconformist/Puritan) “Matthew Henry on 2 Corinthians 3:6: Here the apostle makes a comparison between the Old Testament and the New, the law of Moses and the gospel of Jesus Christ, and values himself and his fellow-labourers by this, that they were able ministers of the New Testament, that God had made them so, Co2 3:6. This he does in answer to the accusations of false teachers, who magnify greatly the law of Moses. I. He distinguishes between the letter and the spirit even of the New Testament, Co2 3:6. As able ministers of the New Testament, they were ministers not merely of the letter, to read the written word”
  11. John (Presbyterian) “Jamieson, Fausset & Brown on John 1:17: For, &c.--The Law elicits the consciousness of sin and the need of redemption; it only typifies the reality. The Gospel, on the contrary, actually communicates reality and power from above (compare Rom 6:14). Hence Paul terms the Old Testament "shadow," while he calls the New Testament "substance" (Col 2:17) [OLSHAUSEN].”

Hebrews (Methodist/Wesleyan) “Adam Clarke on Hebrews 8:6: Now hath he obtained a more excellent ministry - His office of priesthood is more excellent than the Levitical, because the covenant is better, and established on better promises: the old covenant referred to earthly things; the new covenant, to heavenly. The old covenant had promises of secular good; the new covenant, of spiritual and eternal blessings.

  14. Jeremiah (Protestant academic) “Tyndale House on Jeremiah 31:32: 31:32-34 The key difference between the new covenant and the one God made with their ancestors is that the Lord would write his instructions deep within his people’s hearts (see Heb 10:16). The old covenant was external and legal, whereas the new covenant would be a vital, person-to-person relationship. The new covenant would emphasize the redeeming, transforming change of an individual’s spiritual nature.”
