• ἐθίζεις (present active indicative, 2nd person singular) – you accustom

Origin & History

The verb ἐθίζω has deep roots in classical Greek, dating back to at least the 5th century BCE. Aristotle frequently employed this term in his ethical writings, particularly in the Nicomachean Ethics, where he emphasized the importance of habituation (ἐθισμός, ethismos) in the formation of virtue. For Aristotle, ethical character was primarily developed through the repeated practice of virtuous actions until they became second nature.

In the Septuagint (LXX), derivatives of ἐθίζω appear in contexts related to established religious customs and traditional practices. For example, in 2 Maccabees 14:30, the term is used to describe the “accustomed” ways in which affairs were conducted. However, the exact form ἐθίζω appears infrequently in the LXX, suggesting its specialized use in particular contexts.

By the time of the New Testament, the word had taken on specific connotations related to Jewish religious customs and practices. This is particularly evident in Luke’s Gospel, where the word appears in connection with the observance of Torah commandments and Temple rituals. The early church fathers, including Clement of Alexandria in his Paedagogus, would later use this term when discussing the formation of Christian habits and disciplines.

Biblical Usage

The most significant occurrence of ἐθίζω in the New Testament is found in Luke 2:27, where it appears in the perfect passive participle form (τὸ εἰθισμένον). This verse describes Yeshua’s parents bringing Him to the Temple “according to the custom of the Law” (κατὰ τὸ εἰθισμένον τοῦ νόμου). This usage highlights the faithful observance of Torah commandments by Joseph and Mary, specifically regarding the presentation of the firstborn son and the purification ritual after childbirth as prescribed in Exodus 13:2,12 and Leviticus 12:1-8.

While the specific verb form ἐθίζω appears only once in the New Testament, its cognates and related forms (particularly ἔθος, ethos) appear multiple times, especially in Luke-Acts. These occurrences demonstrate the importance of established religious practices in the life of the early Jewish-Christian community. They also highlight the tension between maintaining traditional customs and embracing the new covenant inaugurated by the Messiah.

• “And when the days of their purification according to the law of Moses were completed, they brought Him up to Jerusalem to present Him to the Lord (as it is written in the law of the Lord, ‘Every male who opens the womb shall be called holy to the Lord’), and to offer a sacrifice according to what is said [κατὰ τὸ εἰθισμένον] in the law of the Lord.” Luke 2:27

Cultural Insights

In first-century Jewish culture, the concept of habitual practice (ἐθίζω) was intricately connected to the broader framework of Torah observance. Jewish religious life was structured around regular practices and customs that reinforced one’s identity as part of the covenant community. The presentation of the firstborn at the Temple, as described in Luke 2:27, was not merely a one-time ritual but part of a comprehensive pattern of faithfulness that shaped Jewish identity.

The Hebrew concept most closely related to ἐθίζω is מִנְהָג (minhag), referring to a custom or traditional practice. While halakha (Jewish law derived from Torah) prescribed the mandatory aspects of religious observance, minhagim (customs) developed organically within communities and families as expressions of devotion. These customs, though not explicitly commanded in Torah, carried significant weight in shaping religious identity and practice. Yeshua Himself observed many such customs while also challenging those that had become empty rituals divorced from their spiritual meaning, as seen in His critique of certain Pharisaic practices in Matthew 15:1-9.

Theological Significance

The concept of habitual practice (ἐθίζω) in Scripture points to the profound biblical truth that faith is not merely intellectual assent but embodied practice. God’s design for human flourishing includes the formation of godly habits that align our lives with His character and commands. The repeated practice of righteousness, as guided by Torah and ultimately fulfilled in the Messiah, shapes our character to reflect the image of God more faithfully.

This understanding challenges the false dichotomy between “law” and “grace” that has sometimes characterized Christian theology. Joseph and Mary’s faithful observance of the Torah’s requirements, as described through the use of ἐθίζω in Luke 2:27, was not legalism but loving obedience. Their habitual practice flowed from a deep relationship with יהוה (Yahweh) and prepared the way for their unique role in raising the Messiah. In the same way, our spiritual disciplines and habits are not meant to earn God’s favor but to position us to receive the grace He freely gives.

The ultimate example of perfect habit formation is Yeshua Himself, who habitually practiced communion with the Father through prayer, Scripture meditation, and faithful observance of the commandments. His perfect habits became the foundation for His perfect obedience, even to death on a cross. Through Him, we receive not only forgiveness for our failures but also the power of the Holy Spirit to form new, godly habits that reflect His character.

Personal Application

Understanding ἐθίζω invites us to examine our own spiritual habits and practices. What customs and disciplines are shaping our character? Are we intentionally forming habits that draw us closer to God and make us more like Yeshua? Just as Mary and Joseph faithfully practiced the customs of Torah, we too are called to develop consistent spiritual rhythms that nurture our relationship with God.

Begin by identifying one spiritual practice—whether prayer, Scripture reading, worship, service, or Sabbath rest—that you can commit to with greater consistency. Remember that habit formation requires both grace and effort. Ask the Holy Spirit to empower your practice while committing to the daily discipline required. Over time, what begins as deliberate effort will become second nature, a habitual expression of your love for God that shapes your character to be more like the Messiah’s.

Did You Know?

• In ancient Greek athletic training, the concept of ἐθίζω was central to the development of athletic excellence. Trainers would have their athletes repeat movements and exercises until they became second nature, believing that the body had to be “habituated” to perform at its highest level. This concept parallels Paul’s athletic metaphors for spiritual training in passages like 1 Corinthians 9:24-27.
• Modern neuroscience has validated the ancient wisdom behind ἐθίζω by demonstrating how repeated actions create neural pathways in the brain that make those actions increasingly automatic. This phenomenon, known as neuroplasticity, shows that our brains physically change through habitual practice, creating a biological basis for character formation. This scientific insight aligns perfectly with the biblical emphasis on the transformative power of spiritual disciplines and godly habits.
• The Jewish concept of hiddur mitzvah (beautifying the commandment), which developed from Torah practices, embodies the spirit of ἐθίζω by encouraging not just minimal compliance with God’s commandments but their enthusiastic and beautiful fulfillment. This principle teaches that habitual obedience should be an expression of joy and creativity rather than mere obligation, transforming duties into delights through consistent practice.

Remember This

ἐθίζω reminds us that faith is not merely what we believe but what we practice until it becomes who we are—our daily habits are silently shaping our eternal character.
