Christians affirm that the Bible is God’s inspired and inerrant Word (2 Timothy 3:16), yet believers do not all interpret every aspect of Scripture the same way. In matters of doctrine, not everything holds the same weight. Some teachings are essential to the faith, others shape how we live or organize our churches, and still others are matters of individual study and conscience.
For the sake of clarity and unity, it is helpful to distinguish between Biblical Convictions, Personal Convictions, and Opinions. This threefold structure helps believers maintain both truth and grace, and to obey Paul’s call to speak “the truth in love” (Ephesians 4:15). The framework also protects the church from legalism, sectarianism, and unnecessary division.
Biblical Convictions (Essentials, First-Tier Doctrines)
Definition:
- Universally accepted truths among all true Christians
- Grounded directly in Scripture and essential to the gospel
- To deny these is to abandon biblical Christianity
Examples :
- The Trinity (Matthew 28:19; 2 Corinthians 13:14)
- Deity and Humanity of Christ (John 1:1,14; Colossians 2:9)
- Virgin Birth (Luke 1:35; Isaiah 7:14)
- Substitutionary Atonement (Isaiah 53:4-6; Romans 5:8)
- Bodily Resurrection of Christ (1 Corinthians 15:14-17)
- Salvation by grace through faith (Ephesians 2:8–9)
- Authority and Inerrancy of Scripture (2 Timothy 3:16; Psalm 19:7)
- Bodily Return of Christ (Acts 1:11; Revelation 22:12)
Biblical convictions are the bedrock of the Christian faith. These doctrines define what it means to be a Christian. Christians across all nations, denominations, and centuries have affirmed these truths. They are not up for negotiation or reinterpretation. To deny them is to affirm “another gospel,” which Paul strongly condemns (Galatians 1:6–9).
These doctrines form the foundation of Christian unity. Believers are called to “contend for the faith that was once for all delivered to the saints” (Jude 3). We must separate from those who reject these truths, whether cults, false teachers, or heretical movements.
Personal Convictions (Second-Tier Doctrines, Denominational Distinctives)
Definition:
- Doctrines held by conviction as biblical
- Often result in different denominations or local church practices
- Faithful Christians may disagree without breaking Christian fellowship
Examples:
- Mode and Subjects of Baptism (Credobaptism vs. Paedobaptism)
- Church Governance (Episcopal, Presbyterian, Congregational)
- Continuation vs. Cessation of Spiritual Gifts
- Role of Women in Ministry (Complementarian vs. Egalitarian)
- Eschatological Systems (Premillennial, Amillennial, Postmillennial)
- Sabbath/Lord’s Day Observance
- Communion Practices (frequency, fencing the table, real presence)
Personal convictions are doctrines that deeply shape how churches are organized, how believers worship, and how pastors teach. They are often the reason believers choose to fellowship in one denomination over another. While these convictions are drawn from Scripture, and often defended with deep study and theological precision, they are not gospel issues.
For example, a Presbyterian and a Baptist will disagree on whether infants should be baptized, but both affirm justification by faith alone and the authority of Scripture. They may worship in separate churches, but they do not condemn each other as unbelievers.
Romans 14 teaches that believers may differ in matters of conviction and still glorify God. Paul says, “Each one should be fully convinced in his own mind” (Romans 14:5), encouraging both confidence and charity.
Opinions (Third-Tier Doctrines, Individual Views)
Definition:
- Issues of individual interpretation or speculation
- Not central to salvation, worship, or church structure
- Believers within the same congregation may disagree freely
Examples:
- Age of the Earth (Young Earth vs. Old Earth)
- Identity of “sons of God” in Genesis 6
- Details of heavenly rewards
- Style of music in worship
- Specific interpretation of symbolic passages (e.g., Ezekiel’s Temple)
- Who wrote Hebrews
- Whether to celebrate holidays like Christmas or Easter
Opinions are matters of conscience, study, and sanctified speculation. They may be interesting and sometimes passionately discussed, but they should never divide believers. In fact, learning to disagree charitably in these areas can strengthen unity, sharpen doctrine, and model humility.
As Paul instructs in Romans 14:19, “So then let us pursue what makes for peace and for mutual upbuilding.” Too often, Christians elevate opinions to the level of gospel, causing unnecessary offense and distraction from the mission of the Church.
Case Study: Eschatology and Doctrinal Weight
Eschatological Views:
- Amillennialism – Millennium is symbolic; Christ reigns now through the Church; final judgment at Christ’s return.
- Postmillennialism – Gospel will triumph through history; Christ returns after a golden age of righteousness.
- Historic Premillennialism – Christ returns before a literal 1000-year reign; resurrection and judgment follow.
- Dispensational Premillennialism – Christ returns in two stages (rapture and second coming); emphasis on Israel-Church distinction; literal 1000-year reign.
Eschatology, or the doctrine of last things, is a classic example of a personal conviction. Faithful Christians throughout church history have differed on how to interpret Revelation 20, the “millennium,” and the sequence of end-time events. All four systems affirm Christ’s future bodily return and final judgment—a biblical conviction—but interpret the details differently.
Trouble arises when believers elevate eschatology to the level of gospel essentials. Some adherents of Dispensational Premillennialism have treated belief in the pre-tribulation rapture as a litmus test for true Christianity. This is not only unwarranted by Scripture but causes confusion and division. Scripture repeatedly warns against overemphasis on speculative matters (Titus 3:9; 1 Timothy 1:4).
Conversely, full preterism, which teaches that all prophecy was fulfilled by AD 70—including Christ’s second coming and the final resurrection—is rightly regarded as heresy. This view contradicts 1 Corinthians 15, which teaches a future bodily resurrection, and Acts 1:11, which promises a visible return of Christ. Denial of these truths undermines the very hope of the gospel.
Why Some Elevate Lesser Doctrines Too Highly
Contributing Factors:
- Youth and Immaturity – Young believers may lack doctrinal categories and overemphasize what’s newly discovered.
- Reactionary Tendencies – Overcorrecting against error can lead to doctrinal extremism.
- Pride and Identity – Finding worth in being “right” can eclipse gospel humility.
- Lack of Discipleship – Without careful teaching, believers struggle to prioritize truth appropriately.
It is common for zealous but immature Christians to latch onto a newly learned doctrine—whether eschatology, Calvinism, or creationism—and treat it as the core of Christianity. While this often stems from genuine passion, it leads to division and misplaced priorities.
Paul’s warning in 1 Corinthians 8:1 rings true: “Knowledge puffs up, but love builds up.” Proper discipleship is key. Seasoned pastors and teachers must help believers distinguish between what is essential, what is important, and what is non-essential.
Can a Heretic Be a Born-Again Christian?
This is a weighty question. The word “heretic” is used in Scripture to describe someone who distorts or denies the gospel (Galatians 1:8; 2 Peter 2:1). But does every heretical belief prove someone is unsaved?
Scripture shows that believers can fall into serious error (James 5:19–20; Galatians 2:11–14). Peter denied Christ three times. Paul confronted Peter publicly for compromising the gospel in Galatians 2, but he did not say Peter was unregenerate.
Therefore, a born-again Christian may temporarily hold heretical views out of ignorance or deception, but if they are truly saved, God will discipline and correct them (Hebrews 12:6). Persistent refusal to repent, however, raises serious doubts about one’s regeneration (Titus 3:10–11).
Conclusion: Unity in the Essentials, Charity in the Non-Essentials
Biblical unity is built on truth rightly prioritized. The Church must stand firm on biblical convictions, extend grace amid personal convictions, and show charity regarding opinions. As the early Reformers taught, “In essentials, unity; in non-essentials, liberty; in all things, charity.”
Let us be a people marked by theological depth, doctrinal clarity, and loving fellowship—always anchored in the gospel and committed to truth with humility.
