In depth

From the study of Hebrews 10:25

Range of meaning

Custom, habit, usual practice; also an established religious or legal custom (Luke 1:9; Acts 6:14; 25:16).

Against the English

KJV 'the manner of some', BSB 'as some have made a habit', WEB 'the custom of some'. All fine. 'Habit' is the most natural modern equivalent.

Used elsewhere in the period

Luke 22:39, Jesus went to the Mount of Olives 'as was his custom'; John 19:40, 'as is the burial custom of the Jews'. It describes a settled, repeated pattern.

From the study of Acts 6:14

Range of meaning

Custom, habit, usage. In Hellenistic Jewish and Lukan usage it also means the established ancestral laws and practices of a people, their constitution as a way of life.

Against the English

'Customs' to a modern ear sounds like folkways, traditions that could change without much loss. Here it means the practices commanded in the Torah that made Israel Israel.

How it drifted

Modern English separates 'law' from 'custom' (a custom is unwritten and optional). Ancient people saw ancestral custom as binding and sacred, especially when it went back to a divine lawgiver.

Used elsewhere in the period

Luke-Acts uses it repeatedly for the Mosaic way of life: 'circumcised according to the custom of Moses' (Acts 15:1), 'not to walk according to the customs' (21:21), 'the customs of the fathers' (28:17), 'customs and controversies of the Jews' (26:3). Josephus speaks of the Jews' ancestral customs (ta patria ethē) as the laws they would die rather than break. 2 Maccabees 11:24–25 and 4 Maccabees 18:5 use similar language for the ancestral law under Seleucid pressure.

From the study of Acts 15:1

Range of meaning

A habit, a usage or established custom. Of a people, it meant their ancestral practices, the inherited way of life that defined them, often with the force of law. Luke uses it more than any other New Testament writer for Jewish practice: the priestly custom (Luke 1:9), the feast custom (Luke 2:42), 'the customs Moses handed down to us' (Acts 6:14), 'not to walk according to the customs' (21:21), 'the customs of our fathers' (28:17).

Against the English

Modern 'custom' suggests tradition or etiquette, something you can drop without real loss. The KJV's 'manner of Moses' sounds even lighter. In Greek, 'the customs' of a people meant its ancestral laws and its identity.

How it drifted

Over time, English 'custom' narrowed toward social habit as distinct from law. Greek made no such sharp divide: a nation's ancestral customs were its constitution.

Used elsewhere in the period

Josephus often speaks of 'the ancestral customs' (τὰ πάτρια ἔθη) of the Jews as their laws, for example Antiquities 20.100 on Tiberius Alexander, who 'did not remain in the ancestral customs'. Greek historians use ἔθη for the binding customs of nations. The Vulgate translates it morem ('the custom').
