Brief

Chapter Summary

In the opening chapter of Reasons to Believe, Scott Hahn challenges the contemporary assumption that religious faith is a subjective, emotional “leap in the dark.” Drawing from his personal intellectual journey—specifically a college-era challenge regarding the biblical basis for infant baptism—Hahn illustrates that genuine faith is a reasonable and intellectually grounded response to objective truth.

Core Thesis Statement

Faith is not an irrational leap or a mere emotional experience; it is a reasonable, intellectually honest response to truth that harmonizes the heart and the mind.

Key Arguments

The Instability of Emotion: Feelings and “spiritual highs” are temporary and fluctuate; therefore, they constitute a weak foundation for a lifelong commitment to truth.
The Biblical Precedent for Infant Baptism: Using the continuity of God’s covenants, Hahn argues that just as infants were included in the Old Covenant through circumcision, they are included in the New Covenant through baptism.
The Harmony of Faith and Reason: Reason helps individuals investigate truth, while faith allows them to trust truths that reason points toward but cannot fully grasp alone.
The Knowability of Divine Mysteries: Although the mysteries of Christianity are unfathomable, they are not unknowable, as God has willed to disclose them through Scripture and creation.
The Intellectual Necessity of Dogma: When officially defined teachings are dismissed in favor of generalized emotion, religion eventually loses its force and collapses.
The Nature of True Apologetics: Effective defense of the faith requires deep preparation, prayer, and humility rather than “snappy answers.”
The Universality of Truth: Following St. Justin Martyr’s principle, Christians can engage with any philosophy or science because “whatever is true is ours.”
