Historical context of the New Testament

The Greco-Roman world in the time of Jesus and the apostles

The New Testament emerged in a world dominated by the Roman empire, with deep influences from the culture GreekThis context was decisive for the expansion of Christianity:

• He Koine Greek language It was the common language of the empire, which facilitated the spread of the gospels and epistles.

• He Roman road system allowed the apostles to travel and communicate quickly between cities.

• There was a partial religious tolerance, which initially allowed Christians to gather as a Jewish sect before they were persecuted.

• Cities were centers of intellectual life, commerce and religion, where new ideas could spread strongly.

Jesus was born and preached in this complex historical context, and his first followers They used existing structures to bring the gospel to every corner of the known world.

Cultural, religious and political influences

Three pillars directly influenced the New Testament era:

• Greek culture: offered philosophy, literature and logic that influenced the thinking and language of the biblical writers.

• The Jewish religion: It was the root of the Christian faith. The New Testament adopts the knowledge of the Old Testament and practices such as the Mosaic law, the temple, and sacrifices.

• Roman political rule: He imposed taxes, maintained order with military force, and demanded loyalty to the emperor, which caused tensions with Christians, who proclaimed Jesus as Lord.

This intersection of cultures produced an environment where The proclamation of a crucified and risen Savior generated impact, confrontation and conversion.

The transition from Judaism to early Christianity

Christianity did not emerge as a new, isolated religion, but as the fulfillment of the promises of Judaism. However, over time it developed its own identity:

• The first Christians were Jews who recognized Jesus as the Messiah.

• They met in synagogues and followed Jewish customs, although reinterpreted in the light of Christ (Acts 2:46).

• The inclusion of Gentiles (non-Jews) without the need for circumcision or Mosaic law was key (Acts 15), generating tension with traditionalist Jews.

• Little by little, the church was consolidated as an independent body, with its own theology, practices, leadership and missionary vision.

This transition was progressive, painful and deeply theological, marking the emergence of a global faith centered on the figure of Christ.

Formation and transmission of the New Testament

When and how were the books of the New Testament written?

The books of the New Testament were written between the years 45 and 100 AD, by apostles and direct witnesses of the events narrated.

• The Gospels They were written between the years 60 and 90 AD, based on oral traditions and eyewitness accounts.

• The epistles of Paul They are the oldest (some written around 50 AD), addressed to specific churches.

• Apocalypse It was probably the last book, written by the apostle John on the island of Patmos.

The authors wrote in response to specific needs: correct errors, strengthen faith, preserve teachings and bear witness to the risen Christ.

The process of copying and preserving manuscripts

Since there was no printing press, the New Testament texts were copied by hand by Christian scribes.

Characteristics of this process:

• The first copies were made in papyrus, a brittle material, and later in parchment, more durable.

• They were distributed in churches, where they they read aloud and were kept as sacred treasures (Colossians 4:16).

• Despite minor copying errors, the high number of manuscripts (more than 5,800 Greek) allows reconstruct the original text with great precision.

• Fragments of the New Testament have been found less than 100 years after its writing, which is exceptional in ancient literature.

This collective effort shows that The early church recognized from the beginning the inspirational and authoritative value of these writings.

The New Testament canon: Who decided which books to include?

He canon It is the set of books recognized as inspired by God. The formation of the New Testament canon was a process guided by the Holy Spirit through the Christian community.

Criteria used:

• Apostolic authorship or direct connection with an apostle (Matthew, Paul, Peter, John).

• Doctrinal conformity with the message of Christ.

• Liturgical and continuous use in churches since the early centuries.

• Confirmation by the Holy Spirit in the hearts of believers.

Important milestones:

• By the end of the 2nd century, there was already a consensus on most books.

• He Muratorian Canon (2nd century) and the Councils of Hippo (393) and Carthage (397) confirmed the 27 books that we know today.

It was not an arbitrary decision, but a recognition of what the church already lived and used as the Word of God.

Key differences between the Old and New Testaments

The Old Covenant vs. the New Covenant

The Old Testament presents the covenant between God and the people of Israel, based on obedience to the law given to Moses. The New Testament introduces a new pact, established by Jesus Christ, open to all humanity.

Fundamental differences:

• He ancient pact required obedience to external commandments and ceremonial rites.

• He new pact, promised in Jeremiah 31:31-34, offers a inner relationship with God, based on faith in Christ.

• In the new covenant, God He writes his law on hearts and offers complete forgiveness through Jesus' sacrifice.

This change represents a spiritual revolution, moving from a system based on merit to one based on grace.

The Mosaic Law and the Grace of Christ

The Mosaic Law (Torah) regulated all aspects of Israel's life: moral, civil, and ceremonial. It was holy and just, but also pointed out the human impossibility of fulfilling it perfectly.

With the coming of Christ:

• The law is fully fulfilled in Him (Matthew 5:17).

• Salvation no longer depends on complying with regulations, but of the undeserved grace (Romans 6:14).

• Obedience arises not by legal obligation, but as a fruit of a relationship with God through the Holy Spirit (Galatians 5:18).

Grace does not cancel out holiness, but empowers the believer to live according to God's will.

Ritual sacrifices vs. the ultimate sacrifice of Jesus

In the Old Testament, animal sacrifices were temporary symbols which covered sin, but could not completely take it away (Hebrews 10:1-4).

With Jesus:

• It is offered himself as a perfect sacrifice, once and for all (Hebrews 10:10-14).

• His blood not only covers, but cleans completely sin.

• The Temple and the Levitical Priesthood are replaced for his eternal work as Heavenly High Priest.

This marks a transition from the symbol to the ultimate spiritual reality, accessible to all believers.

The New Testament and the unity of the Bible

How it connects to Old Testament prophecies

The New Testament does not break with the Old, but continues it and fulfills it. Jesus and the apostles constantly quote the Hebrew Scriptures as prophetic authority.

Examples of compliance:

• Virgin birth of Jesus (Isaiah 7:14; Matthew 1:22-23).

• Ministry in Galilee (Isaiah 9:1-2; Matthew 4:13-16).

• Crucifixion and suffering of the Messiah (Psalm 22; Isaiah 53; Acts 8:32-35).

• Resurrection (Psalm 16:10; Acts 2:25-31).

These connections show that The Bible is one redemptive story, which finds its culmination in Christ.

The continuity of the divine plan of redemption

From Genesis to Revelation, the Bible reveals a coherent plan of salvation, designed by God from eternity.

Elements of the plan:

• The promise to Abraham: a blessing for all nations (Genesis 12:3).

• The Law and the Prophets: preparation for the Messiah.

• Jesus: fulfillment, mediator of the new covenant and restorer of all things.

• The church: bearer of the gospel until Christ's return.

• Apocalypse: final consummation with a new heaven and a new earth.

Nothing in biblical history is accidental: Everything points to God's redemptive work through Christ.

The figure of Christ as the fulfillment of the promises

Jesus does not only appear in the New Testament: It is present in shadow and promise from the beginning.

Christ fulfills:

• The role of prophet as God's final spokesman (Deuteronomy 18:15; Hebrews 1:1-2).

• The role of priest as mediator between God and men (Psalm 110:4; Hebrews 5:5-10).

• The role of king as heir to the throne of David (2 Samuel 7:12-14; Luke 1:32-33).

• The promises of the covenant made to Abraham, Moses and David.

In Jesus they converge all the hopes of Israel and all the need for redemption of humanityHe is the common thread that unites the entire Bible.
