Origin & History
The verb ἔθω (ethō) has deep roots in classical Greek literature, appearing in the works of Homer, Herodotus, and Thucydides to describe established customs and habitual practices. In Plato’s Republic, the term connects habits to the formation of character (ἦθος), suggesting that repeated actions shape one’s moral constitution. This understanding influenced Greek philosophical thought about virtue formation through habitual practice.
In the Septuagint (LXX), ἔθω appears primarily in contexts describing religious customs and ritual observances. For instance, in 2 Maccabees 4:11, it describes the abandonment of established Jewish customs (τὰ νόμιμα καταλύων, τὰς παρανόμους ἐθισμοὺς ἐκαίνιζεν). By the Hellenistic period, the concept had become central to discussions about cultural identity, particularly for Jews navigating the tensions between ancestral traditions and Greco-Roman influences.

Biblical Usage
In the New Testament, ἔθω appears most prominently in its perfect participle form εἰωθώς (eiōthōs) or as part of the phrase κατὰ τὸ εἰωθός (kata to eiōthos), meaning “according to custom.” Its first appearance in Matthew 27:15 relates to Pilate’s customary practice of releasing a prisoner during the feast, revealing how even Roman governors accommodated local religious customs. This usage highlights the binding force of tradition in ancient jurisprudence.
The term carries significant weight in Luke’s Gospel, where it emphasizes how Yeshua and the early disciples honored Jewish customs while introducing the new covenant. This tension between continuity and transformation forms a key theological motif in Luke-Acts, showing how the Messiah fulfilled rather than abolished established Jewish practices.
- “Now at the feast the governor was accustomed [εἰώθει] to release for the crowd any one prisoner whom they wanted.” Matthew 27:15
- “And He came to Nazareth, where He had been brought up; and as was His custom [κατὰ τὸ εἰωθὸς], He entered the synagogue on the Sabbath, and stood up to read.” Luke 4:16
- “And according to Paul’s custom [κατὰ δὲ τὸ εἰωθὸς], he went to them, and for three Sabbaths reasoned with them from the Scriptures.” Acts 17:2
Cultural Insights
In the ancient Mediterranean world, customs (ἔθη) were not merely preferences but carried the force of law. This concept is captured in the Latin phrase “consuetudo pro lege servatur” (custom is observed as law). For first-century Jews, adherence to ancestral customs was a matter of identity preservation under Roman rule. When Pilate released a prisoner “according to custom” (Matthew 27:15), he was acknowledging the power of established practice in maintaining social stability.
The Jewish custom of synagogue attendance on Sabbath, referenced in Luke 4:16, had developed during the Babylonian exile when Temple worship was impossible. By the first century, this custom had become so ingrained that synagogues functioned as centers of Jewish life throughout the Diaspora. When Luke notes that Yeshua entered the synagogue “according to His custom,” he emphasizes the Messiah’s commitment to communal Jewish practice, even as He redefined its meaning through His teaching and ministry.
Theological Significance
The biblical usage of ἔθω reveals the delicate balance between honoring established customs and embracing divine transformation. Yeshua consistently demonstrated respect for Jewish traditions—attending synagogue “according to His custom” (Luke 4:16)—while also challenging practices that had become empty formalism. This pattern reveals Yahweh’s heart for authentic worship that transcends mere habit while respecting the communal expressions of faith that bind believers together.
Paul’s missionary strategy similarly reflected this balance. Acts describes how he reasoned in the synagogues “according to his custom” (Acts 17:2), showing respect for Jewish institutions while proclaiming the revolutionary message of the Messiah. This approach reveals the divine wisdom of contextualizing the gospel within existing cultural frameworks while inviting transformation from within. The theological tension between continuity and change, tradition and revelation, forms a central theme in God’s redemptive work throughout Scripture.
Personal Application
Understanding ἔθω challenges believers to examine their own customs and habits of faith. What practices have we maintained out of genuine conviction, and which have become mere routine? Yeshua’s example invites us to honor traditions that connect us to the community of faith while ensuring that our customs express authentic devotion rather than empty formalism.
Consider developing intentional spiritual customs that shape your character over time. Just as ἔθω is linguistically connected to ἦθος (character), your regular practices form your spiritual identity. Whether it’s Sabbath observance, prayer at fixed times, or regular Scripture reading, these customs can create a rhythm of remembrance that keeps God’s presence at the center of your life. The key is allowing these practices to remain Spirit-filled rather than becoming mechanical obligations.

Did you Know?
- Did you know that the Greek concept of ἔθω (becoming accustomed) was so central to ancient ethical philosophy that Aristotle based his theory of virtue on it? He argued that virtue is formed through habitual practice—we become just by performing just actions repeatedly until they become second nature. This philosophical understanding likely informed how early Jewish believers integrated new Messianic practices with traditional observances.
- Did you know that Pilate’s custom of releasing a prisoner during Passover (Matthew 27:15) is not attested in Roman historical records outside the Gospels? This suggests it may have been a localized practice specific to Judea, developed to maintain peace during the festival when Jerusalem’s population swelled with pilgrims and nationalist sentiments ran high. Such accommodations to local customs were common in Roman provincial administration.
- Did you know that the modern English word “ethics” derives from the Greek ἦθος (ēthos), closely related to ἔθω? This linguistic connection reveals how ancient Greek thought linked habitual practices (ἔθω) to the formation of moral character (ἦθος)—a concept that profoundly influenced both Jewish and Christian understandings of spiritual formation. When Paul urges believers to “put on the new self” in Ephesians 4:24, he’s drawing on this same understanding that new habits form new character.
Remember This
Custom without conviction becomes empty ritual, but tradition infused with truth creates powerful rhythms of remembrance that shape both individual character and community identity in the image of the Messiah.
