Why does the church fail if Christ sanctifies?
Ephesians 5:25–27: If Christ sanctifies the church, how do we explain the church’s historical failures and corruption?

Understanding Ephesians 5:25–27

Ephesians 5:25–27 reads: “Husbands, love your wives, just as Christ loved the church and gave Himself up for her to sanctify her, cleansing her by the washing with water through the word, and to present her to Himself as a glorious church, without stain or wrinkle or any such blemish, but holy and blameless.”

These verses emphasize the sacrificial love of Christ toward the church, culminating in the promise of her being made “holy and blameless.” Yet history shows moments, even extended stretches, where corruption, abuses, and moral failings permeated various facets of the institutional church. The question arises: How do we reconcile Christ’s sanctifying work with such failures?


Definition of Sanctification

Sanctification refers to the process by which believers, and by extension the collective body of believers, are set apart and made ever more conformed to the character of Christ. While Scripture affirms that believers are already sanctified through Christ’s sacrifice (1 Corinthians 6:11), it also teaches ongoing sanctification, with the ultimate fulfillment anticipated in the future (Philippians 1:6). Ephesians 5:25–27 points to both a present reality—Christ has sanctified the church—and a future goal—she will one day be “without stain or wrinkle.”


Ideal vs. Reality

In Scripture, “the church” is often presented in two interrelated concepts:

1. The Universal (or Invisible) Church: The total body of true believers united in Christ through faith and empowered by the Holy Spirit.

2. The Visible Church: The institutional expression—local congregations, denominations, and all earthly forms through which Christians gather and worship.

While the universal church is, in Christ’s eyes, continuously being sanctified and ultimately will be presented perfect in Him, the visible church struggles with sin because it consists of fallible individuals (Romans 7:21–24). Historical corruption does not negate Christ’s promise; rather, it underscores humankind’s need for ongoing transformation.


Comparisons to Israel’s Failures

Throughout the Old Testament, God’s chosen people frequently fell into corruption and idolatry (Judges 2:10–12; 2 Kings 17:7–17). Yet God remained faithful, repeatedly calling them back to repentance. Similarly, the New Testament church has experienced periods of revival and growth—and times of serious moral, doctrinal, and practical decline. These cyclical patterns do not nullify God’s sanctifying work; they highlight His enduring mercy and ultimate plan to refine His people (Malachi 3:2–3).


Biblical and Historical Assurance

1. Scriptural Continuity: Despite failures, the church’s core testimony to Christ’s death and resurrection remains unbroken. New Testament manuscripts, such as p46 (dating to roughly AD 200), attest to early written preservation of Pauline letters, including Ephesians. The consistent message penned in these texts—God’s redemptive mission and Christ’s sanctifying power—has survived doctrinal controversies, schisms, and church corruption.

2. Christ’s Preservation of His Church: Jesus declared, “I will build My church, and the gates of Hades will not prevail against it” (Matthew 16:18). This promise indicates divine preservation despite human fault. Archaeological discoveries, such as ancient house churches in regions like Dura-Europos (3rd century AD), confirm an unbroken lineage of worshippers upholding apostolic teachings through persecution and upheaval.

3. Historical Examples of Reformation and Renewal: Corruption periodically reached critical points (e.g., in medieval Europe), yet each time, voices within the church and from outside the established hierarchy called believers back to Scripture. Movements of genuine repentance—whether from the early church fathers, medieval reformers, or contemporary revivals—inevitably arose, pointing to Christ’s active role in sanctifying His church over the centuries.


Progressive Sanctification in Human Beings

The reason corruption remains possible lies in the tension between the “already” and “not yet.” Believers are “already” redeemed but have not “yet” experienced the fullness of their glorification (Romans 8:23). Until the final consummation of all things, people remain prone to sin and even grave institutional failures. Nonetheless, Christ’s sanctification is at work, moving toward a completed process of purification when He returns (Revelation 19:7–9).


Human Agency and Moral Responsibility

God dignifies individuals by granting free will within His sovereign plan. Hence, human leadership in the visible church can be tempted by power, wealth, or social influence. Instances of immorality, abuses of authority, or doctrinal distortion arise when sinful hearts deviate from the explicit teachings of Scripture (Matthew 15:8–9). This, however, does not undermine the “washing with water through the word” that Christ bestows, for His sanctifying work continues through believers who align themselves with His truth.


The Role of Accountability

Scripture encourages correction and church discipline to address failings (Galatians 6:1; Matthew 18:15–17). Throughout history, faithful believers have responded to corruption by calling for repentance and reform, emphasizing the authority of God’s word. The ability to self-correct and refine is part of how the Spirit sanctifies the church over time.


Philosophical and Behavioral Insights

In behavioral science, a community’s members can falter when social conformity overrides moral convictions. But when believers collectively repent and return to biblical principles, societal benefit often follows. This cycle provides further evidence that moral alignment with Christ’s word yields observable transformation. Hence, while examples of corruption can be discouraging, they also highlight the ongoing necessity of personal and corporate sanctification.


Encouragement and Practical Implications

Rely on Scripture’s Authority: Continue to test teachings and practices by the Word of God. The Berean mindset (Acts 17:11) fosters biblical discernment that guards against corruption.

Pursue Personal Sanctification: Christians are called to “be holy in all you do” (1 Peter 1:15). Personal integrity and Christlike behavior contribute to maintaining the church’s purity.

Trust in Christ’s Ultimate Victory: As Ephesians 5:27 assures, Christ will present the church without blemish. Historical failings underscore why we need a Savior—not that the Savior’s work has failed.


Conclusion

The discrepancy between the church’s divine calling to holiness in Ephesians 5:25–27 and the failures documented in history testifies to humanity’s ongoing struggle with sin, not to any shortcoming in Christ’s sanctifying power. Christ’s sanctification is a present and future reality, culminating in the final redemption of His people. While human corruption is real and grievous, it does not invalidate God’s word or Christ’s promise. Rather, these failures illustrate the continued necessity of reformation, repentance, and returning to the sure foundation of Scripture. Through it all, the faithful Savior leads His people forward, shaping and purifying the church until she stands radiant and blameless in His presence.
