As we journey through our Christian walk, it’s essential to have a strong foundation in the core beliefs that define our faith. Christianity, though diverse in its expressions and denominations, shares a common set of fundamental truths that unite us as believers under one Lord, Jesus Christ.
These five basic beliefs serve as the pillars that shape our understanding of God, our identity as His children, and our response to His love and grace. Whether you’re a new believer seeking clarity on these invaluable teachings or a seasoned disciple looking for a refresher, this article will delve into the scripture (primarily drawing from the New King James Version, NKJV) and share profound insights on the tenets that lie at the very heart of Christianity.
So, grab your Bible, find a comfortable spot, and let’s explore the core beliefs that have bound Christians together for over two millennia!

I. Understanding the Core of Christianity: The 5 Basic Beliefs
It is crucial for every believer to understand and ground themselves in the 5 basic beliefs that form the core of Christianity. These fundamental doctrines distinguish our faith from other worldviews and religions. Although Christian practices may vary across denominations, all Christians unite in belief of these essential teachings:
- Belief in the Holy Trinity: God is one, yet exists in three persons – the Father, the Son (Jesus Christ), and the Holy Spirit (Matthew 28:19). This eternal relationship signifies that God is in perfect harmony, and the incarnation of Jesus Christ demonstrates that God is active in human history.
- Belief in Jesus Christ as the Son of God and Savior: Jesus is both fully divine and fully human, conceived by the Holy Spirit and born of the Virgin Mary (Luke 1:35). He lived a sinless life, died on the cross for the atonement of our sins, and physically rose from the dead three days later (1 Corinthians 15:3-4), ultimately conquering sin and death.
- Belief in Salvation by Grace through Faith: We are saved by God’s grace, through faith in Jesus Christ (Ephesians 2:8-9). This salvation is unmerited, meaning it is a gift from God that we can’t earn by our own efforts or good deeds (Titus 3:5). This belief emphasizes that our salvation is solely based on the work of Christ on the cross.
- Belief in the Authority of the Bible: The Bible, composed of the Old and New Testaments, is the inspired, infallible Word of God (2 Timothy 3:16). It is the ultimate authority for Christian faith and practice, providing guidance, wisdom, and instruction for living in accordance with God’s will (Psalm 119).
- Belief in the Second Coming of Christ: Jesus Christ will return in glory to judge the living and the dead (Acts 1:11; Revelation 19:11-16). This belief gives Christians hope for the future and a motivation to live lives marked by holiness, love, and justice.
As Christians, it is important to nurture a deeper understanding of these core beliefs and grow in our faith. Doing so enables us to have a strong foundation in God’s Word, allowing us to answer the questions and challenges that arise from non-believers and other religions. By embracing these basic doctrines, we can better reflect Christ in our lives and be ambassadors for the Gospel, sharing the transformative power of God’s grace with those around us. Remember, “the word of the Lord is pure; He is a shield to all who put their trust in Him” (Proverbs 30:5).
II. The Foundation of Christian Faith: An In-Depth Look at What Christians Believe
When we delve deeper into the foundation of Christian faith, there are multiple key beliefs and concepts that come to light, guiding our relationship with Christ and understanding of His teachings. Here, we will discuss a few essential elements of Christianity, such as the belief in one God, understanding the Trinity, the importance of Jesus Christ, and the significance of the Holy Scriptures.
First and foremost, Christians firmly believe in the existence of one true God, who is eternal and the creator of the universe (Deuteronomy 6:4, NKJV). This belief in monotheism is the core of Christianity, distinguishing it from other religions. Secondly, the concept of the Trinity holds that this one God exists in three persons: God the Father, God the Son (Jesus Christ), and God the Holy Spirit, all equal and united in purpose and essence (Matthew 28:19, NKJV).
Jesus Christ plays a crucial role in Christian beliefs as He is considered both fully God and fully man, and His life, death, and resurrection all serve as a testament to His divine mission, which ultimately brought reconciliation between humankind and God (John 1:14; 1 Corinthians 15:3-4, NKJV).
Finally, Christians regard the Holy Scriptures, also known as the Bible, as the inspired word of God, allowing believers to not only acquire knowledge and wisdom but to develop a deeper understanding of God’s will for their lives (2 Timothy 3:16-17, NKJV).
III. How These 5 Basic Beliefs Shape a Christian’s Life and Worldview
The following 5 basic beliefs are integral to shaping a Christian’s life and worldview. Firstly, the belief that God is sovereign means that Christians submit to His divine authority and plan (Proverbs 16:9). They trust that nothing happens without His knowledge and that He has a purpose for everything (Romans 8:28). This perspective encourages Christians to rely on God and seek His guidance in all decision-making.
Secondly, believing in the Trinity (Father, Son, and Holy Spirit) as one God, Christians maintain that the Father, the Son (Jesus Christ), and the Holy Spirit all actively work and communicate with them (2 Corinthians 13:14). This helps them experience a personal relationship with God and to better comprehend the different ways He reveals Himself.
Next, Christians hold firm to the conviction that salvation is by grace alone through faith in Jesus Christ (Ephesians 2:8-9). This belief reminds them that their efforts to please God or gain His favor are not what lead to eternal life. Instead, they place their faith in Jesus Christ, who took upon Himself the punishment for humanity’s sins.
Following this, Christians lean on the authority of the Bible as their primary source of direction and guidance. They believe that Scripture is inspired by God (2 Timothy 3:16) and is crucial for teaching, correcting, and equipping them for righteous living.
Lastly, the belief in the Great Commission (Matthew 28:19-20) encourages Christians to be witnesses by sharing the gospel and making disciples of all nations. This belief spurs them to invest in evangelism, missions, and ministry work as a reflection of their faith in Jesus Christ.
Conclusion
In conclusion, these five basic beliefs of Christianity – the deity of Christ, salvation by grace through faith, the resurrection, the Gospel, and the monotheistic aspect – form the very core of our faith. As Christians, it is crucial that we understand and firmly hold onto these beliefs as we navigate through our lives, drawing strength and guidance from them.
Let us be reminded of what Paul writes in Ephesians 2:8-9 (NKJV): “For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast.” As believers, we should rejoice in the knowledge that God loves us and has graciously provided the way to eternal life through Jesus Christ, our Lord, and Savior.
As we continue to walk in our faith, may we find encouragement in Hebrews 11:6 (NKJV): “But without faith, it is impossible to please Him, for he who comes to God must believe that He is and that He is a rewarder of those who diligently seek Him.” May we be inspired to delve deeper into the Scriptures, to be transformed by its wisdom, and to share the Gospel’s life-changing message with those around us.
As Christians, it is our privilege and responsibility to share these basic beliefs with others, reflecting the light of Christ in our lives, and inviting them to experience the joy and salvation found in following Jesus Christ. Let us remember the Great Commission in Matthew 28:19-20 (NKJV): “Go therefore and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all things that I have commanded you; and lo, I am with you always, even to the end of the age. Amen.”
Let us stand firm in our faith, anchored by these five basic beliefs, and share the love of Christ with a world that desperately needs it. May God bless you as you continue to grow in understanding, fellowship, and service for His kingdom.
