What Are Doctrines?
Doctrines are the core teachings and beliefs of Christianity—the essential truths about God, Christ, salvation, and the Christian life that have been revealed through Scripture and developed throughout church history. The word "doctrine" simply means "teaching" or "instruction." In the New Testament, Paul writes in 2 Timothy 4:2 that we should "preach the word; be ready in season and out of season; reprove, rebuke, and exhort, with complete patience and teaching" (ESV). These teachings are not merely abstract ideas but living truths meant to transform our hearts and minds.
The foundation of all Christian doctrine is Jesus Christ Himself. In John 7:16-17, Jesus explains, "My teaching is not my own. It comes from the one who sent me. Anyone who chooses to do the will of God will find out whether my teaching comes from God or whether I am speaking on my own." This principle reminds us that sound doctrine always points us toward God's character and His redemptive purposes. Doctrines like the Trinity, the incarnation, justification by faith, and the resurrection are not theological puzzles but revelations that deepen our worship and devotion.
Key Doctrines in Scripture
Throughout Scripture, certain doctrines emerge as foundational to the Christian faith. The doctrine of grace—God's unmerited favor toward sinners—is central to the Gospel message. Paul writes in Ephesians 2:8-9, "For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast" (ESV). The doctrine of redemption through Christ's sacrifice is equally vital. Hebrews 9:28 declares, "Christ was sacrificed once to take away the sins of many people" (NIV).
Other essential doctrines include the authority and sufficiency of Scripture (2 Timothy 3:16-17), the nature of God as holy and just, the reality of sin and its consequences, and the promise of Christ's return. These doctrines work together to create a comprehensive understanding of God's plan for humanity. They answer life's deepest questions: Who is God? What is my purpose? How can I be reconciled to God? What does He expect of me?
Living Out Our Doctrine
Understanding doctrine is not an intellectual exercise alone—it must transform how we live. In Titus 1:9, Paul writes that leaders should be "holding firm to the trustworthy word as taught, so that he may be able to give instruction in sound doctrine and also to rebuke those who contradict it" (ESV). As believers, we are called to both hold fast to truth and live it out faithfully. When we grasp the doctrine of God's sovereignty, we learn to trust Him with our circumstances. When we embrace the doctrine of sanctification, we pursue holiness in our daily choices.
The Canadian evangelical church thrives when we ground our faith firmly in biblical doctrine. This doesn't mean being rigid or judgmental; rather, it means being rooted and built up in Christ (Colossians 2:7). Encourage your church community to study Scripture deeply, ask good questions, and let doctrine shape not just what you believe, but who you become.
All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the servant of God may be thoroughly equipped for every good work. — 2 Timothy 3:16-17 (NIV)
