Comparing the Testaments

As we explore the Old and New Testaments, we’ll examine key areas such as their foundational elements, laws, historical settings, prophecies, portrayals of the Messiah, and their literary structures.

The insights will deepen our understanding of the Bible as a unified yet diverse compilation of scriptures.

Foundational Differences

The Old Testament, forming the Hebrew Bible, is the scriptural groundwork for understanding the history of Israel and God’s initial covenant with humanity, starting from creation in Genesis.

By contrast, the New Testament captures the life of Jesus, early Christianity, and articulates the New Covenant.

Covenants and Laws

With the Old Covenant, the focus is on law, ritual, and moral directives, primarily directed at the Hebrews.

The New Testament introduces a New Covenant, emphasizing grace and truth through Jesus Christ, fulfilling and transforming the Old Testament law.

Historical Context

The historical context of the Old Testament spans from the creation to post-exilic Israel, recorded over centuries in Hebrew.

The New Testament documents a narrower historical frame, in Greek, where the narrative unfolds within the first century and reflects the spread of Christianity beyond Israel to Gentile communities.

Prophets and Prophecies

Prophets in the Old Testament deliver God’s messages, often warning of judgment but also foreshadowing the coming of the Messiah.

In the New Testament, prophecies find their fulfillment in the life and works of Jesus, as He is revealed to be the prophesied Messiah in Scriptures.

Messiah in Scriptures

The Old Testament anticipation of the Messiah evolves across various books, with prophecies outlining His role in God’s plan.

The New Testament presents Jesus as the anticipated Messiah, substantiating claims through Old Testament references and prophecies.

Literary Structures and Genres

Both testaments comprise diverse literary genres: the Old Testament contains law codes, narratives, wisdom literature, and prophecy while the New Testament includes Gospels, epistles, and apocalyptic literature.

Notably, the vocabulary and style reflect differences in language, culture, and time.

Frequently Asked Questions

This section explores common inquiries about the differences and nuances between the Old Testament and the New Testament, addressing topics such as God’s portrayal, structure and content of the books, the biblical canon, presentations of love, intertestamental references, and sacrificial practices.

What is the difference in the portrayal of God between the Old and New Testaments?

In the Old Testament, God is often portrayed as the creator and enforcer of the law, emphasizing His justice and might.

One finds Him delivering the Ten Commandments to Moses on Mount Sinai.

On the other hand, the New Testament focuses on God’s grace and forgiveness, primarily through the person of Jesus Christ, who embodies God’s love for humanity.

For example, in the book of John, Jesus is described as the word made flesh, revealing God’s love and truth in human form.

How do the books of the Old Testament compare to those of the New Testament in terms of structure and content?

The Old Testament books include various genres such as law codes, history, poetry, and prophecy, spread across a longer time frame and written in Hebrew.

They lay the foundational history and covenantal relationship between God and Israel.

In contrast, the New Testament books, written in Greek, are comprised mainly of the Gospels, Acts, Epistles, and Revelation, focusing on Jesus’ life, teachings, and the early church.

They tend to have a more consistent central message concerning Christ’s salvific work.

Can you explain the concept of ‘canon’ in relation to the books of the Bible?

The term ‘canon’ refers to the collection of books that are accepted as authentically inspired scripture by a religious community.

The Old Testament canon varies among different Christian traditions, with Jews and Protestants recognizing 39 books, while Catholic and Orthodox churches include additional texts known as the Deuterocanonical books.

The New Testament canon consists of 27 books universally recognized among Christian denominations.

How is the concept of love presented differently in the Old Testament as compared to the New Testament?

While the Old Testament emphasizes God’s steadfast love and loyalty to Israel through covenants and laws, such as His promise to Abraham in Genesis, the New Testament encapsulates love in the person of Jesus.

Here, love is exemplified by sacrifice and service, with the ultimate example being Jesus’ sacrifice on the cross, as portrayed in the Gospels and explained in detail in letters like First John, where it says that “God is love” and that this love was made manifest through Jesus.

In what ways does the New Testament reference or build upon the teachings of the Old Testament?

The New Testament writers often reference Old Testament prophecies and teachings to explain and validate Jesus’ ministry.

They saw Jesus as fulfilling messianic prophecies, like those in Isaiah, and the moral and ethical teachings of the Old Testament are reiterated and expanded upon, particularly in Jesus’ Sermon on the Mount, which reflects the spirit of the commandments.

What are the distinctions between sacrificial practices in the Old Testament and the New Testament?

In the Old Testament, sacrificial systems involved regular offerings of animals, grains, and incense, serving various purposes like atonement for sin.

This is thoroughly outlined in Levitical law.

Conversely, the New Testament presents Jesus’ death as the ultimate and final sacrifice, fulfilling the need for atonement as detailed in the book of Hebrews.

This establishes a new covenant between God and believers, with faith in Jesus’ sacrifice being central to redemption.
