What is Christianity and what do Christians believe?

1. Summary of the Question

The question, “What is Christianity and what do Christians believe?” addresses the core of the Christian faith, exploring its foundational beliefs and practices. Christianity is a monotheistic religion centered on the life, teachings, death, and resurrection of Jesus Christ. Christians believe in the Bible as the inspired Word of God and hold that salvation is found through faith in Jesus Christ alone. This answer will explore what Christianity is, its historical and biblical foundations, and the core beliefs that define Christian doctrine.

2. Context and Background

To understand Christianity and what Christians believe, it’s essential to examine its historical, cultural, and literary context. Christianity began in the first century AD in the Roman province of Judea. It emerged from Judaism, with its foundational scriptures being the Hebrew Bible (Old Testament) and the teachings of Jesus and His apostles recorded in the New Testament.

The early Christians were Jews who believed Jesus of Nazareth was the promised Messiah (Christ) foretold in the Hebrew Scriptures. They believed that Jesus’ life, death, and resurrection fulfilled the Old Testament prophecies and inaugurated a new covenant between God and humanity. Christianity quickly spread throughout the Roman Empire and beyond, despite persecution, because of its transformative message of grace, forgiveness, and eternal life through faith in Jesus Christ.

3. Biblical Foundation (NASB 2020)

Several key scriptures in the NASB 2020 translation provide a biblical foundation for understanding Christianity and its core beliefs:

• John 3:16 (NASB 2020): “For God so loved the world, that He gave His only Son, so that everyone who believes in Him will not perish, but have eternal life.”
  This verse summarizes the heart of the Christian message: God’s love for humanity is demonstrated in sending His Son, Jesus Christ, to offer salvation through faith.
• Romans 10:9-10 (NASB 2020): “That if you confess with your mouth Jesus as Lord, and believe in your heart that God raised Him from the dead, you will be saved; for with the heart a person believes, resulting in righteousness, and with the mouth he confesses, resulting in salvation.”
  Salvation in Christianity is based on confessing Jesus as Lord and believing in His resurrection, affirming the centrality of faith in Jesus for salvation.
• Ephesians 2:8-9 (NASB 2020): “For by grace you have been saved through faith; and this is not of yourselves, it is the gift of God; not a result of works, so that no one may boast.”
  Christianity teaches that salvation is a gift of grace from God, not something earned by human efforts or good works.
• 1 Corinthians 15:3-4 (NASB 2020): “For I delivered to you as of first importance what I also received, that Christ died for our sins according to the Scriptures, and that He was buried, and that He was raised on the third day according to the Scriptures.”
  This passage highlights the core of Christian belief: the death, burial, and resurrection of Jesus Christ as the foundation of the Gospel message.
• 2 Timothy 3:16-17 (NASB 2020): “All Scripture is inspired by God and beneficial for teaching, for rebuke, for correction, for training in righteousness; so that the man or woman of God may be fully capable, equipped for every good work.”
  Christians believe that the Bible is the inspired Word of God, serving as the ultimate authority for faith and practice.
• Matthew 22:37-40 (NASB 2020): “And He said to him, ‘You shall love the Lord your God with all your heart, and with all your soul, and with all your mind.’ This is the great and foremost commandment. The second is like it, ‘You shall love your neighbor as yourself.’ Upon these two commandments hang the whole Law and the Prophets.”
  Jesus summarizes the ethical and moral teachings of Christianity, emphasizing love for God and others as the greatest commandments.

These verses collectively affirm the core tenets of Christianity: belief in Jesus Christ as the Son of God and Savior, the centrality of His death and resurrection, salvation by grace through faith, the authority of Scripture, and the call to love God and others.

4. Addressing Other Perspectives

There are various interpretations and perspectives on Christianity and its beliefs:

1. Secular or Cultural Views: Some see Christianity merely as a moral or ethical system without acknowledging its spiritual and theological claims. However, Christianity is not just a philosophy or set of moral teachings but a faith centered on the person and work of Jesus Christ and His redemptive mission.
2. Other Religious Perspectives: Religions like Islam, Hinduism, and Buddhism have different understandings of God, salvation, and the afterlife. Christianity uniquely teaches salvation through faith in Jesus Christ alone, distinguishing it from works-based or multiple-path approaches.
3. Liberal or Progressive Christianity: Some modern interpretations of Christianity may emphasize social justice, inclusion, and moral teachings while downplaying the need for personal faith in Jesus Christ and the authority of Scripture. While these perspectives seek to make Christianity more relevant, they often diverge from traditional biblical teachings.

The biblical perspective presents Christianity as a unique faith based on the revelation of God through Jesus Christ and His Word, calling for a personal relationship with God and transformation through His grace.

5. Clarifying Misunderstandings

A common misconception is that Christianity is about earning one’s way to Heaven through good works or moral living. However, the Bible clearly teaches that salvation is by grace through faith in Jesus Christ, not by works (Ephesians 2:8-9). Good works are the result of salvation, not the means to achieve it (James 2:17-18).

Another misunderstanding is that Christianity is exclusive and intolerant. While Christianity does teach that Jesus is the only way to God (John 14:6), it also emphasizes God’s love for all people and the invitation for everyone to come to faith in Jesus (John 3:16).

6. Practical Application and Relevance

Understanding Christianity and its core beliefs has significant implications for daily living:

• Living in Relationship with God: Christianity teaches that through faith in Jesus Christ, believers enter into a personal relationship with God. This relationship is nurtured through prayer, reading the Bible, and worship, leading to spiritual growth and transformation (John 15:5).
• Loving God and Others: Christians are called to love God wholeheartedly and to love others as themselves, reflecting Jesus’ teachings in their lives (Matthew 22:37-40). This involves acts of kindness, compassion, justice, and service.
• Sharing the Gospel: Christians are called to share the message of salvation with others, inviting them to experience the hope, forgiveness, and new life found in Jesus Christ (Matthew 28:19-20).

Practical reflections for Christians include:

• Grow in Faith and Understanding: Regularly study the Bible to deepen your understanding of Christian beliefs and grow in your relationship with God.
• Live Out Your Faith: Demonstrate the love of Christ in your daily interactions, serving others and living with integrity and grace.
• Engage in Community: Be part of a local church or Christian community that encourages growth, accountability, and mission.

7. Encouragement and Conclusion

Christianity is a faith centered on Jesus Christ, His death and resurrection, and the message of salvation by grace through faith. Christians believe in the authority of the Bible as God’s Word and strive to live out the teachings of Jesus by loving God and others. This faith is not about following a set of rules or earning favor with God but about entering into a life-transforming relationship with Him through Jesus. Believers are encouraged to grow in their faith, live out their beliefs in love and truth, and share the hope of the Gospel with a world in need. As we align ourselves with God’s will, loving what He loves and rejecting what He hates, we embody the heart of Christianity and reflect God’s grace and truth to those around us.
