Love First Love: One / Ephesians 4:1-6
The Inseparable Link Between Doctrine and Conduct
The architecture of Paul’s Epistle to the Ephesians presents a deliberate theological blueprint. The first three chapters contain no explicit moral imperatives; rather, they present an expansive exposition of God’s eternal redemptive plan in Christ Jesus. In this opening movement, the Apostle delineates the unsearchable riches of grace bestowed upon the church: eternal election, adoption, redemption through Christ’s blood, spiritual regeneration, and the reconciliation of estranged humanity into one new body. Doctrinal truth forms the immovable foundation upon which Christian identity rests.
A marked transition occurs at the outset of the fourth chapter. Moving from indicative declarations of what God has accomplished to imperative commands regarding how the redeemed ought to live, the text introduces dozens of ethical exhortations. This shift from belief to behavior, however, must never be misconstrued as a transition from grace to works-righteousness. Western individualistic tendencies frequently bifurcate the Christian life, treating the gospel as merely an initiatory rescue while reducing subsequent sanctification to autonomous moral effort. Paul fiercely resisted this error in his letter to the Galatians, rejecting the notion that what was begun by the Spirit could be perfected through human self-reliance.
Galatians 3:3 (NASB)
Are you so foolish? Having begun by the Spirit, are you now being perfected by the flesh?
The gospel that saves is the very gospel that sustains. Christian ethics do not exist to purchase divine favor; rather, they serve as the natural, Spirit-empowered outflow of a reality already accomplished. The call to Christian conduct is fundamentally an invitation to live out the truth of who the believer has already become in Jesus Christ.
Walking Worthy of the Divine Calling
Paul initiates the practical section of the epistle by appealing directly to his readers while imprisoned for the gospel.
Ephesians 4:1 (NASB)
Therefore I, the prisoner of the Lord, implore you to walk in a manner worthy of the calling with which you have been called,
The Greek term translated as “worthy” (axios) conveys the image of a balance scale. It denotes that which is equal in weight, corresponding directly to an established standard, much like an axle maintaining the alignment and equilibrium of a vehicle. To walk in a manner worthy of one’s calling is not an attempt to earn that calling, but an obligation to ensure that outward behavior accurately corresponds to the weight of the gospel received.
When a profound disconnect exists between theological profession and daily conduct, the witness of the gospel becomes severely distorted. Believers are called to bear the name of Christ before an watching world. In His High Priestly Prayer, Jesus interceded not only for His immediate disciples but for all future generations of believers, praying specifically that their manifest unity would substantiate the truth of His divine mission.
John 17:20-21 (NASB)
’I do not ask on behalf of these alone, but for those also who believe in Me through their word; that they may all be one; even as You, Father, [are] in Me and I in You, that they also may be in Us, so that the world may believe that You sent Me.
Before Paul addresses the application of the gospel in speech, personal worship, marriage, parenting, societal structures, or spiritual warfare, he identifies the primary arena wherein the gospel must first be demonstrated: the corporate life and mutual communion of the church.
Preserving What Christ Has Established
The initial imperative governing Christian relationships directs believers toward the preservation of spiritual unity.
Ephesians 4:3 (NASB)
being diligent to preserve the unity of the Spirit in the bond of peace.
Significantly, the Apostle does not instruct believers to manufacture, invent, or negotiate unity. Scripture nowhere commands the church to produce oneness from its own ingenuity, because Christ has already created it. Through His cross, the dividing wall of hostility between disparate peoples has been dismantled, abolishing the enmity that formerly separated humanity from God and from one another. The solemn responsibility assigned to the church is not the creation of unity, but its vigilant defense and preservation against all forces of division.
Furthermore, biblical unity must never be confused with uniformity. Uniformity demands external sameness, pressuring diverse individuals into identical cultural expressions, personal preferences, or superficial molds. Biblical unity, by contrast, thrives amid redeemed diversity. While subsequent passages celebrate the variety of spiritual gifts and individual backgrounds within the body, Paul first establishes the non-negotiable doctrinal foundation upon which all true fellowship stands.
The Seven Pillars of Christian Oneness
To anchor the church against fragmentation, Paul presents a sevenfold confession of oneness, structured around the Triune God.
Ephesians 4:4-6 (NASB)
[There is] one body and one Spirit, just as also you were called in one hope of your calling; one Lord, one faith, one baptism, one God and Father of all who is over all and through all and in all.
These seven declarations form the theological core of the Christian faith. Three of these affirmations explicitly reflect the Trinitarian nature of the Godhead: one Spirit who regenerates and empowers the church, one Lord Jesus Christ who accomplished redemption, and one God and Father who reigns sovereignly over all creation.
Because there is only one true and living God, true spiritual fellowship cannot exist across pluralistic assertions that syncretize divergent worldviews. The Christian faith is defined by a singular object of trust: the exclusive sufficiency of Jesus Christ as the only mediator between God and humanity.
John 14:6 (NASB)
Jesus said to him, ’I am the way, and the truth, and the life; no one comes to the Father but through Me.
Flowing from this singular faith are one body, one baptism, and one shared hope. The “one baptism” denotes the internal, spiritual immersion of the believer into the body of Christ by the Holy Spirit at the moment of conversion, which is visibly signified through water baptism. This rite identifies the believer with the death, burial, and resurrection of Jesus Christ.
Romans 6:3-4 (NASB)
Or do you not know that all of us who have been baptized into Christ Jesus have been baptized into His death? Therefore we have been buried with Him through baptism into death, so that as Christ was raised from the dead through the glory of the Father, so we too might walk in newness of life.
Every believer across geographical boundaries, generational divides, and local assemblies belongs to this single body, bound together by the same eschatological hope: the glorious return of Christ and eternal communion with God. This shared reality establishes a comprehensive unity that is simultaneously theological, relational, and missional.
The Four Virtues of Corporate Preservation
Maintaining the structural integrity of this divine unity amidst human weakness requires practical, everyday virtues. Paul outlines four specific dispositions necessary for safeguarding the peace of the body.
Ephesians 4:2 (NASB)
with all humility and gentleness, with patience, showing tolerance for one another in love,
The first virtue is humility (tapeinophrosyne), which literally signifies lowliness of mind. In classical Greco-Roman culture, humility was deemed a shameful vice, associated with weakness and subjugation. The gospel inverted this societal standard. Christ embodied ultimate humility by willingly setting aside His divine privileges to take on the form of a servant and submit to the death of the cross.
Philippians 2:5-8 (NASB)
Have this attitude in yourselves which was also in Christ Jesus, who, although He existed in the form of God, did not regard equality with God a thing to be grasped, but emptied Himself, taking the form of a bond-servant, [and] being made in the likeness of men. Being found in appearance as a man, He humbled Himself by becoming obedient to the point of death, even death on a cross.
Humility requires believers to abandon self-exaltation, setting aside pride of status, intellect, or background to prioritize the spiritual well-being of others.
The second virtue, gentleness or meekness (praotes), was likewise despised in antiquity. Far from denoting feebleness, biblical meekness refers to immense power brought under deliberate restraint, exemplified by a powerful steed brought under the control of a bridle. It is the capacity to endure mistreatment without vindictive retaliation, reflecting the posture of Christ when He refused to revile those who crucified Him.
The third virtue is patience (makrothumia), literally translated as “long-suffering.” It represents the enduring willingness to bear with the flaws, spiritual immaturity, and slow sanctification of fellow believers. Because all Christians are works in progress, the body must exercise steadfast forbearance rather than premature abandonment or harsh condemnation.
Finally, this long-suffering is operationalized through “bearing with one another in love” (anechomai). This posture goes beyond passive endurance; it entails actively shouldering the burdens of others within the bonds of self-giving love. While secular culture often redefines tolerance as indifferent affirmation of autonomy, biblical forbearance involves stepping into the messiness of community to gently, truth-filledly direct souls toward the transforming power of Christ.
The Witness of the One Body
When local assemblies embody these virtues, theological tribalism and petty rivalries give way to a compelling display of gospel reconciliation. The church ceases to view itself as an isolated entity and instead rejoices in the broader work of God across kingdom-minded congregations. In a fractured and hostile world, the preservation of supernatural unity stands as an undeniable testimony to the validity of the Christian message.
This corporate reality finds its most profound visible expression in the celebration of the Lord’s Supper. In the bread and the cup, the church looks backward in remembrance of Christ’s broken body and shed blood, looks forward in anticipation of the eternal heavenly banquet, and looks around at the gathered body of redeemed sinners. In that shared participation, individual identities merge into a single corporate witness, testifying that there is indeed one body, one Spirit, and one Lord over all.
