ἐκπλήρωσις

completion, fulfillment

Definition

The noun ἐκπλήρωσις (ekplērōsis) denotes the act of bringing something to its full and intended conclusion, emphasizing a thorough or complete fulfillment. In its sole New Testament occurrence in Acts 21:26, it refers to the 'completion' of the days of a Nazirite vow's purification ritual, indicating the final, formal act that satisfies the vow's requirements. While closely related to the more common πλήρωσις (plērōsis, G4138), which also means 'fulfillment,' ἐκπλήρωσις can carry a stronger sense of bringing a process to its ultimate end or final stage. This concept of definitive completion can be applied theologically to God's promises and purposes reaching their appointed terminus.

Biblical Usage

ἐκπλήρωσις is used only once in the New Testament, in Acts 21:26. Here, it describes the specific action Paul undertook to 'complete' the days of a Nazirite vow for four men, a ritual act of purification in the Jerusalem temple. The context is one of ceremonial law and ritual observance, showing the word's application to the formal conclusion of a prescribed religious period or obligation. Its singular usage limits observable patterns, but it fits within Luke's detailed narrative of Jewish customs in Acts.

Etymology

Derived from the preposition ἐκ (ek), meaning 'out of' or 'from,' combined with the noun πλήρωσις (plērōsis, G4138), meaning 'a filling' or 'fulfillment.' The compound form intensifies the root idea, suggesting a fulfillment that is brought 'out to its end' or a completion that is fully accomplished. It is a cognate of the verb πληρόω (plēroō, G4137), 'to fill' or 'fulfill,' which is used extensively in the New Testament for fulfilling scripture, time, or law.

Semantic Range

Though used only once, ἐκπλήρωσις contributes to the rich biblical theme of fulfillment, particularly regarding God's covenants and the culmination of His plans. Understanding this Greek term highlights the definitive nature of certain fulfillments, such as the completion of the Old Testament ceremonial law in Christ (e.g., Matthew 5:17). It enriches reading by underscoring that God's purposes are not merely partially met but are brought to their appointed and perfect conclusion, a concept central to the narrative of redemption.

In its cultural context in Acts 21:26, ἐκπλήρωσις is tied directly to the Jewish Nazirite vow (Numbers 6:1-21). Completing such a vow involved specific sacrifices and rituals at the temple, marking a public, ceremonial end to a period of dedicated separation. The word's usage reflects a formal, religious, and communal understanding of 'completion,' differing from a modern, often private or abstract, sense of finishing a task.

πλήρωσις (plērōsis, G4138) — A more general term for fulfillment or filling, without the compounded emphasis on finality. τελείωσις (teleiōsis, G5050) — Focuses on bringing to perfection or maturity, often in a moral or spiritual sense. συντέλεια (synteleia, G4930) — Emphasizes a joint completion or consummation, often of an age.
