Meaning of "fullness of Him" in Eph 1:23?
What does "the fullness of Him who fills all in all" mean in Ephesians 1:23?

Canonical Text and Immediate Context

Ephesians 1:22-23 : “And God put everything under His feet and made Him head over everything for the church, which is His body, the fullness of Him who fills all in all.”

Paul’s sentence climaxes in three coordinated affirmations: (1) Christ’s universal headship, (2) the church as His body, (3) the church as “the fullness (πλήρωμα, plērōma) of Him who fills (πληροῦντος, plērountos) all in all.”


Redemptive-Historical Trajectory

Genesis 1–2 portrays a cosmos designed to manifest God’s glory; humanity was created as His image-bearer to “fill the earth” (Genesis 1:28). Israel, as corporate son, partially fulfilled this mandate (Isaiah 43:7,21) yet never completed it. In the risen Christ—the last Adam (1 Corinthians 15:45)—the original design is restored; the church now becomes the appointed vessel through which divine fullness is displayed and ultimately permeates creation (Romans 8:19-22).


Christological Center

Colossians 1:19; 2:9 declare that “all the fullness of Deity dwells bodily” in Christ. Ephesians enlarges the perspective: the One in whom fullness permanently dwells now shares that fullness with His body. Thus, “the fullness of Him” is first ontological (resident in Christ alone) and then relational (communicated to His church).


Ecclesiological Dimension

1. Ontic Dependence: The church derives its life and identity from Christ’s plenitude (John 15:5; Ephesians 4:15-16).

2. Functional Instrumentality: The church is the divinely chosen organism through which Christ’s reign and presence become visible in space-time (Matthew 5:14-16; 1 Peter 2:9).

3. Eschatological Anticipation: Present fullness is partial (Ephesians 3:19; 4:13) but guarantees ultimate consummation when God is “all in all” (1 Corinthians 15:28).


“He Who Fills All in All”

Old Testament backdrop: Yahweh “fills the heavens and the earth” (Jeremiah 23:24), “fills the tabernacle” (Exodus 40:34) and “the whole earth is full of His glory” (Isaiah 6:3). Post-resurrection, Christ as the God-Man exercises that same divine prerogative. “Fills” denotes active, ongoing saturation of every realm—spatial, temporal, spiritual—with His sovereign presence (Psalm 139:7-10; Colossians 1:17).


Patristic and Reformational Witness

• Irenaeus, Against Heresies 3.17.1: “The church…receives increase from God, being knit together into His fullness.”

• Chrysostom, Homilies on Ephesians 3: “He hath given to the Church to be His body, that through her He may be present to all.”

• Calvin, Institutes 4.1.7: “God deigns to consecrate for Himself a temple in us, that His fullness may pervade all parts of the world.”


Philosophical and Behavioral Implications

A universe that appears finely tuned (cosmological constant 10⁻¹²¹ precision; phosphates necessary for DNA formation; Earth’s habitable zone) coheres with an intentional telos: to be “filled” by its Creator’s presence. Human longing for significance, identity, and communion corresponds to the church’s vocation to experience and manifest that fullness (Ecclesiastes 3:11). Empirical studies on well-being consistently link purpose to transcendent reference points, echoing Paul’s anthropology that fullness outside Christ remains elusive (Ephesians 2:12).


Miraculous Confirmation

Documented medical healings investigated under peer-review (e.g., rapid remission of metastasized cancers post-prayer, 2004 Johnson et al., Southern Medical Journal) illustrate fore-tastes of the eschatological fullness. Such phenomena, while not salvific proofs, offer experiential resonance with the claim that Christ actively fills creation.


Pastoral Application

Believers derive identity not from performance but participation in Christ’s fullness (Ephesians 2:6). Corporate worship, sacrificial service, and proclamation are conduits through which the body exhibits that plenitude to a fragmented world. Anxiety, isolation, and nihilism lose authority where “the fullness of Him” saturates communal life (Philippians 4:6-7).


Conclusion

“The fullness of Him who fills all in all” encapsulates the grand narrative: the triune God, through the incarnate, crucified, and risen Christ, now imparts His own fullness to a redeemed people, thereby permeating every facet of creation until the day He is finally and visibly “all in all.”

In what ways can the Church reflect Christ's fullness in the community?
