ΤΕΛΕΙΩΣΙΣ (teleiwsis) — Lexarithmos 1560 · Etymology, Meanings

Definition

According to the Liddell-Scott-Jones Lexicon, teleiosis (ἡ) primarily means "completion, accomplishment, fulfillment" and "perfection, making perfect." The word derives from the verb teleioō, which in turn comes from the adjective teleios, meaning "complete, perfect, accomplished," itself stemming from the noun telos, "end, purpose, fulfillment." Its semantic journey is rich, covering a wide range of concepts from the simple completion of an action to spiritual and moral perfection.

In classical philosophy, teleiosis is closely linked to the concept of telos as the ultimate end or final cause (causa finalis) of a being or process. Aristotle, for instance, uses telos to describe entelecheia, the full realization of a thing's potential. Teleiosis, in this context, is the achievement of this entelecheia, the state in which something has reached its full and ideal form.

In religious and theological discourse, particularly in the Hellenistic period and the New Testament, teleiosis acquires deeper dimensions. In the mystery religions, it refers to the ritual initiation leading to "perfection" or complete knowledge. In the New Testament, and especially in the Epistle to the Hebrews, teleiosis is used to describe the spiritual perfection achieved through Christ, in contrast to the inability of the Mosaic Law and the Levitical priesthood to bring about true perfection. It signifies the state of complete salvation and moral integrity before God.

The word, therefore, does not merely denote the cessation of a process but rather a qualitative completion, the attainment of an ideal standard, or the fulfillment of a predetermined purpose. It is the culmination, the final state in which nothing is lacking, and everything is in harmony with its original design.

Etymology

τελείωσις ← τελειόω ← τέλειος ← τέλος (root TEL-/TELE-)

The root TEL-/TELE- is an Ancient Greek root belonging to the oldest stratum of the language, with the core meaning of "end," "purpose," or "completion." From this basic concept, various meanings developed concerning the achievement of a goal, the fulfillment of a function, or the state of completeness. Its etymological path is purely internal to Greek, with a clear evolution from the noun telos to its derivative verbs and adjectives.

Cognate words sharing the TEL-/TELE- root include the noun telos (end, purpose, tax), the verb teleō (to complete, perform, pay), the adjective teleios (complete, perfect, initiated), the verb teleioō (to make perfect, complete), the noun teletē (initiation, rite, mystery), and the adjective telesphoros (bringing to an end, accomplishing). Other derivatives are atelēs (incomplete, imperfect, untaxed), synteleō (to help accomplish), apotelesma (result, completion), and telōnēs (tax-collector). This word family illustrates the variety of applications of the core concept of completion and purpose.

Word Family

TEL-/TELE- (root of telos, meaning "end, purpose, completion")

The root TEL-/TELE- forms the core of an extensive family of words in Ancient Greek, all revolving around the concept of "end" as a conclusion, purpose, or completion. From this fundamental meaning, derivatives developed that describe the act of completion, the quality of being complete, the rituals that lead to it, as well as the financial aspects of fulfilling obligations. This root, of Ancient Greek origin, demonstrates the internal coherence of the Greek language in developing complex concepts from simple bases.

In Ancient Texts

As a central concept, teleiosis appears in significant texts that highlight the evolution of its meaning.

«εἰ οὖν τελείωσις διὰ τῆς Λευιτικῆς ἱερωσύνης ἦν, τίς ἔτι χρεία κατὰ τὴν τάξιν Μελχισεδέκ ἕτερον ἀνίστασθαι ἱερέα καὶ οὐ κατὰ τὴν τάξιν Ἀαρών λέγεσθαι;»

If therefore perfection was through the Levitical priesthood, what further need was there for another priest to arise according to the order of Melchizedek, and not to be designated according to the order of Aaron?

Apostle Paul, Epistle to the Hebrews 7:11

«τὸ γὰρ τέλος ἑκάστου ἡ τελείωσίς ἐστιν.»

For the end of each thing is its completion.

Aristotle, Politics 1252b34

«τῆς δὲ τελειώσεως οὐκ ἔστιν ὅρος, ἀλλ’ ἀεὶ προκόπτομεν.»

Of perfection there is no limit, but we are always progressing.

Gregory of Nyssa, On the Life of Moses PG 44, 377C
