LEXARITHMOS 526

Definition

According to the Liddell-Scott-Jones Lexicon, αἵρεσις initially means "the act of taking, grasping, seizing," but quickly acquires the sense of "choice, preference." This fundamental meaning of choice is key to understanding its subsequent evolution.

In the classical period, αἵρεσις refers to free will and the choice of a way of life or action. Plato, for instance, uses the term for the soul's choice before incarnation. In the Hellenistic period, its meaning shifts to describe a "school of thought" or "philosophical sect" (e.g., Stoics, Epicureans), denoting a group that has chosen a specific set of doctrines.

With the advent of Christianity, particularly in the New Testament, αἵρεσις is initially used to describe various "factions" or "schools" within Judaism (e.g., Pharisees, Sadducees). However, gradually, and especially among the Church Fathers, the term acquires the negative connotation of "heretical teaching" or "religious heresy," meaning a doctrine that deviates from orthodox belief, implying a choice that leads to separation from the community.

Etymology

αἵρεσις ← αἱρέω (root αἱρ-, meaning "to take, grasp, choose")
The word αἵρεσις derives from the verb αἱρέω, which possesses a broad semantic range including "to take, seize, grasp, capture" as well as "to choose, prefer." The suffix -σις indicates the action or result of the verb's action. The evolution of its meaning from the material act of taking to the abstract concept of choice and, eventually, to a school or doctrine, reflects the word's intellectual and social application.

Cognate words include the verb αἱρέω, the adjective αἱρετός ("choosable, preferable"), the noun προαίρεσις ("preference, moral choice"), and compounds such as διαίρεσις ("division, separation") and ἀναίρεσις ("destruction, abolition"). All these words retain the core meaning of taking, choosing, or separating.

Main Meanings

  1. Act of taking, seizing, capturing — The original, literal meaning of the verb αἱρέω, transferred to the noun as an action. (E.g., «αἵρεσις πόλεως» - capture of a city).
  2. Choice, preference, decision — The most common meaning in classical Greek, referring to free will and the selection between alternatives. (Plato, 'Republic' 617e).
  3. Way of life, profession, occupation — An extension of the concept of choice, referring to a chosen path or manner of living. (Xenophon, 'Cyropaedia' 1.2.2).
  4. Philosophical school, doctrine, sect — In the Hellenistic period, it refers to a group of people adhering to specific principles or teachings. (Diogenes Laertius, 'Lives of Philosophers').
  5. Religious faction, sect — In the New Testament, it is used for groups within Judaism (e.g., Pharisees, Sadducees) or early Christian groups. (Acts 5:17, 15:5).
  6. Division, dissension, schism — In the Apostle Paul, the word begins to acquire a negative connotation, implying discord and separation within the Christian community. (1 Corinthians 11:19).
  7. Heresy, heterodoxy — The final, dogmatic meaning among the Church Fathers, where αἵρεσις is a doctrine deviating from orthodox belief, leading to excommunication from the Church. (Ignatius of Antioch, Irenaeus).

Word Family

αἱρ- / αἱρε- (root of the verb αἱρέω, meaning "to take, choose")

The root αἱρ- / αἱρε- is exceptionally productive in ancient Greek, generating a large family of words centered around the concepts of taking, seizing, but primarily of choosing and preferring. From the literal act of "taking," it evolved into abstract concepts like "choice" and "decision," and later into social and religious distinctions such as "school" or "heresy." Each family member illuminates a different aspect of this fundamental human action: the act, the result, the quality, or the direction of choice.

In Ancient Texts

The progression of αἵρεσις from choice to heresy is reflected in significant texts of ancient literature and the New Testament.

«τὴν αἵρεσιν τοῦ βίου»
the choice of life
Plato, Republic 617e
«ἀνέστη δέ τις Φαρισαῖος ἐν τῷ συνεδρίῳ, ὀνόματι Γαμαλιήλ, νομοδιδάσκαλος τίμιος παντὶ τῷ λαῷ, καὶ ἐκέλευσεν ἔξω βραχὺ τοὺς ἀνθρώπους ποιῆσαι, καὶ εἶπεν πρὸς αὐτούς· Ἄνδρες Ἰσραηλῖται, προσέχετε ἑαυτοῖς ἐπὶ τοῖς ἀνθρώποις τούτοις τί μέλλετε πράσσειν. πρὸ γὰρ τούτων τῶν ἡμερῶν ἀνέστη Θευδᾶς, λέγων εἶναί τινα ἑαυτόν, ᾧ προσεκλίθη ἀνδρῶν ἀριθμὸς ὡσεὶ τετρακοσίων· ὃς ἀνῃρέθη, καὶ πάντες ὅσοι ἐπείθοντο αὐτῷ διελύθησαν καὶ ἐγένοντο εἰς οὐδέν. μετὰ τοῦτον ἀνέστη Ἰούδας ὁ Γαλιλαῖος ἐν ταῖς ἡμέραις τῆς ἀπογραφῆς καὶ ἀπέστησεν λαὸν ὀπίσω αὐτοῦ· κἀκεῖνος ἀπώλετο, καὶ πάντες ὅσοι ἐπείθοντο αὐτῷ διεσκορπίσθησαν. καὶ τὰ νῦν λέγω ὑμῖν, ἀπόστητε ἀπὸ τῶν ἀνθρώπων τούτων καὶ ἀφετε αὐτούς· ὅτι ἐὰν ᾖ ἐξ ἀνθρώπων ἡ βουλὴ αὕτη ἢ τὸ ἔργον τοῦτο, καταλυθήσεται· ἐὰν δὲ ἐκ Θεοῦ ᾖ, οὐ δυνήσεσθε καταλῦσαι αὐτούς· μήποτε καὶ θεομάχοι εὑρεθῆτε. ἐπείσθησαν δὲ αὐτῷ, καὶ προσκαλεσάμενοι τοὺς ἀποστόλους δείραντες παρήγγειλαν μὴ λαλεῖν ἐπὶ τῷ ὀνόματι τοῦ Ἰησοῦ καὶ ἀπέλυσαν αὐτούς.»
Then a Pharisee named Gamaliel, a teacher of the law held in honor by all the people, stood up in the Council and ordered the men to be put outside for a little while. Then he said to them, “Men of Israel, consider carefully what you intend to do to these men. For some time ago Theudas appeared, claiming to be somebody, and about four hundred men rallied to him. He was killed, and all his followers were dispersed and came to nothing. After him, Judas the Galilean appeared in the days of the census and led a revolt. He too was killed, and all his followers were scattered. Therefore, in the present case I advise you: Leave these men alone and let them go. For if their purpose or activity is of human origin, it will fail. But if it is from God, you will not be able to stop these men; you will only find yourselves fighting against God.” His speech persuaded them. They called the apostles in and had them flogged. Then they ordered them not to speak in the name of Jesus and let them go.
Acts of the Apostles 5:34-40
«δεῖ γὰρ καὶ αἱρέσεις ἐν ὑμῖν εἶναι, ἵνα οἱ δόκιμοι φανεροὶ γένωνται ἐν ὑμῖν.»
For there must be factions among you, so that those who are approved may become evident among you.
Apostle Paul, 1 Corinthians 11:19

Isopsephic Words (526)

Words from the Liddell-Scott-Jones lexicon with the same lexarithmos (526) but different roots, offering interesting comparisons.

γέννησις
«γέννησις» (526) symbolizes origin and creation, whereas αἵρεσις, though initially choice, can lead to separation and departure from original unity. One is a beginning, the other can be the beginning of an end to unity.
μαντεῖον
The «μαντεῖον» (526), the place where divine decisions are received, contrasts with human «αἵρεσις» (choice). While the oracle offers guidance, heresy is a human choice that can deviate from divine will.
ἱέρισσα
The «ἱέρισσα» (526) is the sacred minister serving the divine, while αἵρεσις, in its negative sense, represents deviation from the sacred order. Both relate to the religious sphere, but with opposing connotations.
ὁμοιογενής
«ὁμοιογενής» (526) means 'of the same kind, homogeneous,' implying unity and similarity. This stands in direct contrast to αἵρεσις, which, especially in its Christian usage, denotes separation and heterodoxy.
ἐφηβία
«ἐφηβία» (526), the period of youth and formation, can be linked to αἵρεσις as the time when young people make their first significant life choices, including philosophical or religious beliefs.
ἡδυλογία
«ἡδυλογία» (526), sweet speech or flattery, can be a means by which heresies are spread, as heretics often use persuasive and pleasing words to attract followers, as Paul warns.
