Theology Abandoned: The Church’s Crisis Of Biblical Ignorance

A recent Barna poll has sent shockwaves through the Christian community, revealing that only 24% of theologically-identified born-again Christians believe in the Trinity. Even worse, among self-identifying Christians, that number drops to a mere 16%--a statistic that, while alarming, should not be surprising given the increasing biblical illiteracy in the Church. 

This core doctrine of the Christian faith, defining God as Father, Son, and Holy Spirit in one Being, is not a theological afterthought; it is foundational to our salvation, our worship, and our very understanding of who God is.

This staggering decline in doctrinal literacy raises urgent questions: How did we get here? And more importantly, how do we reverse this alarming trend?

The poll's findings are not an isolated phenomenon. Over the past two decades, numerous studies have documented the erosion of biblical knowledge among professing Christians. The American Bible Society's annual "State of the Bible" report consistently shows a decline in Bible engagement. Lifeway Research has reported that only 32% of Protestant churchgoers read their Bible daily.

We now live in an era where many churchgoers cannot articulate the Gospel, name the Ten Commandments, or explain fundamental doctrines like justification, sanctification, and the Trinity. The fruit of this ignorance is evident: a growing number of professing believers are embracing a watered-down, cultural Christianity that bears little resemblance to the faith "once for all delivered to the saints" (Jude 1:3).

A primary cause of this crisis is the Church's increasing neglect of sound teaching. Many modern churches, in their effort to attract large crowds and avoid controversy, have abandoned expository preaching and robust doctrinal instruction in favor of feel-good messages and self-help-style sermons. 

While encouragement and practical application have their place, they must never come at the expense of truth. The apostle Paul warned that a time would come when people "will not endure sound teaching, but having itching ears they will accumulate for themselves teachers to suit their own passions" (2 Timothy 4:3). That time is now.

Further, many pastors assume that their congregants already know core Christian teachings. But in a culture saturated with secularism, relativism, and competing worldviews, we must be intentional in forming disciples who know what they believe and why. It is not enough to assume that attendees will "pick up" doctrine through osmosis. The Church must deliberately and repeatedly teach foundational truths.

Adding to this crisis is the rise of secular thinkers and social media influencers, particularly on platforms such as TikTok and YouTube, who have become the primary "theologians" of our day. Many of these voices promote spirituality while rejecting the biblical Gospel, shaping the spiritual views of millions. While they may offer thought-provoking insights on personal growth, they lack theological grounding and often mix Christianity with New Age mysticism or self-centered ideology.

The danger is not merely that secular figures are filling a void left by the Church; it is that many Christians are turning to them as their primary source of worldview formation rather than to Scripture and sound biblical teaching. This is why we see a growing number of "spiritual but not religious" individuals who appreciate Jesus as a wise teacher but reject His divinity, the Holy Spirit's role, and the reality of the Trinity.

The road back to theological literacy and biblical faithfulness begins with the Church recommitting itself to teaching the whole counsel of God (Acts 20:27). We must:

Prioritize Expository Preaching - Pastors and teachers must systematically teach Scripture, ensuring that congregants understand the full narrative of the Bible, not just isolated verses or inspirational messages.

Emphasize Discipleship - Churches must foster deep, intentional discipleship, equipping believers to grow in their faith, understand doctrine, and live out biblical truth in everyday life.

Encourage Daily Scripture Engagement - Christians must be immersed in God's Word. Churches should provide resources, reading plans, and accountability structures to encourage regular Bible study.

Correct False Teaching Boldly - In an era of confusion, pastors and leaders must courageously confront and correct theological errors, ensuring that congregants are not led astray by secular philosophies or distorted gospels.

Model Deep Faith and Worship - The way we worship shapes what we believe. Churches must ensure that their worship services, prayers, and sacraments reflect deep reverence for the triune God rather than mere entertainment or emotional experience.

The decline of belief in the Trinity is a symptom of a larger crisis--a crisis of biblical illiteracy, shallow discipleship, and cultural conformity. But it is not too late. God is raising up a remnant that longs for truth, that desires to know Him deeply, and that will stand against the tide of theological compromise. The question before us is simple: Will we be counted among them?

It is time for the Church to wake up. The integrity of our witness, the faith of future generations, and the very soul of the Church depend on it.
