The 16 Fundamental Truths are the essential biblical doctrines that provide a firm foundation for the Assemblies of God and millions of Spirit-filled believers worldwide. These truths anchor our faith in Scripture, clarifying our understanding of God, salvation, the Holy Spirit, and the hope we have in Jesus Christ’s return.
If you are new to Christian doctrine, this guide offers a simple starting point for understanding core biblical truths and growing a stronger faith in Jesus. We will walk through what these truths mean, why they matter, and how they can shape your daily life as you follow Christ through resources at www.boundlessonlinechurch.org.
Understanding the Foundation: Why Doctrine Matters
For many, the word "doctrine" can sound intimidating or overly academic. However, at its heart, doctrine simply means "teaching." When we study the 16 Fundamental Truths, we aren't just memorizing a list of rules; we are exploring the heart of God as revealed in His Word. These truths act as a compass, keeping us steady when life feels chaotic and ensuring our faith is built on the rock of Scripture rather than the shifting sands of culture.
Boundless Online Church is committed to helping you navigate these truths with clarity and grace. Whether you are a new believer or have been following Christ for decades, returning to these fundamentals brings fresh strength to your soul. If you’re looking for a community to grow with, we invite you to join our Bible Study Club, where we dig deeper into these topics every week.
The Four Cardinal Doctrines
While all sixteen truths are vital, the Assemblies of God highlights four as "Cardinal Doctrines." These are the pillars of our ministry and the primary focus of our teaching. They represent the core experience of a Spirit-filled life.
1. Salvation Through Jesus Christ
Salvation is the cornerstone of everything we believe. We believe that humanity was created good but fell into sin, separating us from God. Salvation is the gift of God’s grace, received through repentance and faith in the Lord Jesus Christ. It is through His shed blood on the cross that we are forgiven and restored to a right relationship with our Creator. If you are searching for peace and a fresh start, we invite you to submit a prayer request and let us walk with you as you discover the life-changing power of Jesus.
2. The Baptism in the Holy Spirit
Following salvation, we believe in a distinct experience called the baptism in the Holy Spirit. This is not for a "special" class of Christians; it is a promise for every believer. This experience provides power for life and service, enduing us with spiritual gifts for the work of the ministry. It is a beautiful empowerment that helps us witness for Christ with boldness and love.

3. Divine Healing
We believe that God still performs miracles today. Divine healing is an integral part of the Gospel, deliverance from sickness is provided for in the atonement and is the privilege of all believers. We believe in the power of the prayer of faith to bring restoration to the broken body, mind, and spirit. You can find many stories of God's faithfulness on our Prayer and Hope blog.
4. The Blessed Hope (The Second Coming)
Our faith is not just for this life; it is anchored in the future. The "Blessed Hope" is the imminent return of Jesus Christ to gather His Church. This truth gives us courage in difficult times, knowing that the struggles of this world are temporary and that we will one day be with the Lord forever.
Exploring the Full 16 Fundamental Truths
Beyond the cardinal doctrines, the remaining truths provide a comprehensive map for Christian living and church health. Let’s look at them grouped by their focus.
The Authority of God and His Word
1. The Scriptures Inspired: The Bible is the inspired Word of God, the infallible rule of faith and conduct. It is our ultimate authority.
2. The One True God: God has revealed Himself as the eternally self-existent "I AM," and has further revealed Himself as embodying the principles of relationship and association as Father, Son, and Holy Spirit.
3. The Deity of the Lord Jesus Christ: Jesus is the eternal Son of God. We affirm His virgin birth, sinless life, miracles, substitutionary work on the cross, bodily resurrection, and exaltation to the right hand of God.
The Human Condition and Restoration
4. The Fall of Man: Man was created upright and good, but by voluntary transgression, fell and thereby incurred not only physical death but also spiritual death, which is separation from God.
9. Sanctification: This is an act of separation from that which is evil, and of dedication unto God. It is a lifelong process of growing more like Jesus.

The Life of the Church
6. The Ordinances of the Church: We practice water baptism by immersion as a public declaration of our faith, and Holy Communion as a remembrance of Christ’s suffering and death.
10. The Church and Its Mission: The Church is the Body of Christ, with a divine mission to evangelize the world, worship God, and build a body of saints being perfected in the image of His Son.
11. The Ministry: A divinely called and scripturally ordained ministry has been provided by our Lord for the purpose of leading the Church in its mission.
The Evidence of the Spirit
8. The Initial Physical Evidence of the Baptism in the Holy Spirit: We believe the initial physical sign of the baptism in the Holy Spirit is "speaking in other tongues," as experienced on the Day of Pentecost in the book of Acts.
The End of the Age
14. The Millennial Reign of Christ: The second coming of Christ includes the rapture of the saints, followed by the visible return of Christ with His saints to reign on earth for one thousand years.
15. The Final Judgment: There will be a final judgment in which the wicked dead will be raised and judged according to their works.
16. The New Heavens and the New Earth: "We, according to His promise, look for new heavens and a new earth wherein dwelleth righteousness."

How to Apply These Truths to Your Life
Studying these truths is only the beginning. The real transformation happens when you take these biblical principles and apply them to your daily routines. For example, knowing that "The Scriptures are Inspired" (Truth #1) should lead us to prioritize daily Bible reading. Understanding "Divine Healing" (Truth #12) encourages us to pray with confidence when we or our loved ones are ill.
If you feel overwhelmed by the depth of these doctrines, start small. Focus on one truth each week. Read the associated Scriptures, talk about it in your small group, and ask the Holy Spirit to reveal how that truth impacts your current circumstances. Our Prayer Wall is a great place to see these truths in action, as our community prays for salvation, healing, and strength based on these very promises.
A Pastoral Prayer for Your Journey
Heavenly Father, we thank You for the clarity and strength found in Your Word. We pray for every person reading this guide, that the 16 Fundamental Truths would become more than just words on a page, but a living reality in their hearts. Grant them wisdom as they study, comfort as they seek Your Spirit, and an unshakable hope in the return of Your Son, Jesus Christ. May their faith be deepened and their lives be transformed by Your grace. In Jesus' name, Amen.
