Introduction

Understanding Greek words is crucial in biblical studies as they often carry nuanced meanings that provide deeper insights into the scriptures. The Greek word ἐφάπαξ (ephapax, Strong’s G2178) is particularly significant due to its use in the New Testament to convey the concept of something happening “once for all” or “in a single occurrence.” This word is essential for interpreting key theological concepts, such as the unique and singular nature of Christ’s sacrifice. Its study also reveals the richness of Greek expressions in both ancient texts and Christian doctrinal development.

Key Information

• The Greek Word: ἐφάπαξ (ephapax) [e-FA-paks]
• Etymology: Derived from the preposition ἐπί (epi, meaning “upon” or “on”) and ἅπαξ (hapax, meaning “once” or “a single time”), together forming the concept of “once for all” or “once and never again.”
• Part of Speech: Adverb.
• The F.O.G Word Choice: Coming Soon.

Primary Meanings

• Once for all: Indicates an action that is completed in a single occurrence, without the need for repetition.
• One time only: Emphasizes the singularity of an event.

Similar Words: ἅπαξ (hapax) [HA-paks], which also means “once” or “one time,” but without the compounded emphasis provided by the prefix ἐπί. The difference between ἅπαξ and ἐφάπαξ is that the latter conveys a stronger sense of finality and completeness in the action, implying that it covers all needs or requirements.

Further Insights: The word ἐφάπαξ is an adverb, which means it modifies verbs to specify the manner, time, or frequency of an action. In this case, it stresses the uniqueness and sufficiency of a single occurrence. Unlike verbs or nouns that have declensions or conjugations, adverbs like ἐφάπαξ remain unchanged in form.
