The Theology of Holiness

In Short

This book serves as a systematic theological treatise on the nature and necessity of "entire sanctification." It argues that beyond the initial experience of salvation, there exists a second, definite work of grace that purifies the heart from the remnants of a sinful nature. By rooting his arguments in scripture and historical typology, the author presents a roadmap for living a life of perfect love. It remains a foundational text for those interested in the historical holiness movement and the theological development of the doctrine of Christian perfection.

The Story

The inquiry begins with a clear, uncompromising assertion: the Christian life is not intended to be a perpetual cycle of sinning and repenting. The author identifies the root of this frustration as "inbred sin"—a lingering, fallen nature that persists even after an individual has been born again. He frames the spiritual life as a journey with two distinct stages. The first stage is justification and regeneration, where the debt of sin is pardoned and a new, spiritual life is imparted to the soul. However, the author insists that this is only the beginning. He describes the second stage, "entire sanctification," as a crisis experience, just as definitive and instantaneous as the first, in which the believer is cleansed of this inward bias toward evil.

To establish this, the author traces the concept of holiness across the breadth of the Bible. He examines the lives of patriarchs like Noah and Abraham, interpreting their experiences as symbolic of the two-stage process of sanctification. He moves through the law, the prophets, and the types—such as the anointing oil used on the vessels of the Tabernacle—to demonstrate that God has always intended for His people to be "set apart." He then turns to the New Testament, analyzing the teachings of Jesus, Paul, Peter, John, and James to show that this doctrine is not a modern invention but the consistent testimony of the apostles.

The argument pivots on the distinction between consecration and sanctification. Consecration, he clarifies, is the human side of the equation—a complete, unreserved surrender of one’s faculties, time, and will to God. Sanctification, conversely, is the divine side—the actual cleansing work performed by the Holy Spirit. He emphasizes that one cannot sanctify oneself; one can only offer the "living sacrifice" that God then makes holy.

The author addresses common objections, such as the claim that "perfect love" is an impossible standard for humans. He counters that perfection in this context does not mean equality with God’s infinite nature, but rather a heart entirely aligned with His, driven by love, and free from motives contrary to His will. He concludes by affirming that this life of holiness is not the end of the journey, but the beginning of a life of perpetual growth. Once the heart is cleansed of the root of sin, the believer is finally free to grow in grace and love without the constant obstruction of an inward, sinful nature. The narrative closes with a personal testimony, inviting the reader to move beyond a life of spiritual struggle and enter into the "rest" of a sanctified heart.

How It Unfolds

The necessity of holiness The text opens by lamenting the indifference of many Christians toward sanctification. It argues that theology is a science of revealed truth, and that a systematic understanding of holiness is essential for the believer’s maturity.

Typology of the patriarchs The author uses the lives of Noah and Abraham to illustrate the two-stage process of grace. He interprets Abraham's departure from his home and eventual arrival in the promised land as a clear parallel to the transition from initial conversion to entire sanctification.

The mechanism of grace This section distinguishes between the "negative" aspect of sanctification—the removal of inbred sin—and the "positive" aspect of being filled with perfect love. The author argues that while purity cannot be increased once attained, the capacity for love grows eternally.

The role of the Trinity The argument deepens by showing how each person of the Godhead contributes to the believer’s holiness. The Father provides the plan, the Son’s blood provides the cleansing, and the Holy Spirit acts as the effective agent who baptizes the heart with fire.

The life of faith The book concludes by grounding the entire experience in the exercise of faith. It dismisses the idea that one must remain in a state of spiritual struggle, instead pointing the reader toward a definitive, present-tense victory in Christ.

The People

The book is less a narrative of characters than an examination of biblical figures as archetypes of spiritual experience. Abraham serves as the primary model of progress, moving through stages of separation until he reaches the "promised land" of sanctified life. Jacob is presented as a man of two distinct, defining experiences—Bethel and Peniel—each representing a deeper level of surrender. Jesus stands as the ultimate example of a life led by love, setting the standard for the believer to follow. The Apostles are treated as authoritative voices, with Paul and John being the most frequently cited for their teachings on the removal of the "carnal mind" and the perfection of love. Throughout, the author positions himself as a fellow traveler, a "chief of sinners" who has found the truth he writes about, standing alongside the reader as they both navigate the requirements of a holy God.

In Its Own Voice

"The negative side is the removal of inbred sin, and is, therefore, a matter of subtraction."

The author describes the cleansing process of sanctification as the removal of an existing, inward corruption.

"There will never be a time in earth nor in Heaven," says the late Dr. Upham, "when there may not be an increase of holy love."

Quoting an influence, the author emphasizes that while sin is removed, the soul's capacity to love God continues to expand infinitely.

"The blood of the Son of God is the ground of our sanctification, but it is the Holy Spirit who is the effective agent in destroying the depravity of our hearts."

This sentence encapsulates the author’s theological balance between the work of the cross and the work of the Spirit.

What It's Really About

At its core, this book is an argument against the idea that the Christian life must be a permanent state of moral struggle. It addresses the fundamental question of whether a believer can ever be truly free from the inner inclination to sin. The author’s argument is that the gospel provides not just a pardon for past mistakes, but a fundamental change of nature. It explores the tension between human responsibility—the act of complete surrender—and divine sovereignty, the act of God’s cleansing. The text is specifically concerned with the "two-stage" model of spiritual development, positioning the second blessing of holiness as the rightful inheritance of every believer rather than a rare, mystical achievement.

Why Read It Today

Readers interested in the history of the holiness movement or those currently wrestling with the frustrations of inconsistent spiritual life will find this book highly relevant. Its tone is earnest, urgent, and deeply theological, written with the confidence of a man who believes he has uncovered a "missing" piece of the modern believer’s experience. The writing is precise, though it reflects the late-19th-century academic style, which can feel dense to a contemporary reader accustomed to shorter, punchier prose.

The author’s frequent use of "glory!" as a punctuating exclamation may strike some as idiosyncratic or dated, yet it reveals the emotional depth of the holiness movement he represents. While the book is unapologetically dogmatic, its warmth and pastoral concern for the reader’s spiritual well-being are evident throughout. Readers should be aware that the book assumes a high degree of biblical literacy and a traditional theological framework. It is not a casual read, but for those seeking a rigorous, systematic defense of the doctrine of sanctification—and a challenge to live a life of "perfect love"—it remains a substantial and transformative resource. Its strength lies in its refusal to offer easy platitudes, instead demanding a total and perpetual commitment to the divine.
