By the first century, synagogues existed in Jewish communities in Judea, Galilee, and throughout the wider Mediterranean world. The Sabbath provided a natural time for people to gather because ordinary work had ceased.
Synagogue gatherings were not identical everywhere, and later synagogue liturgies should not simply be transferred backward into the period of Jesus. Scripture reading and teaching, however, are well attested.
The synagogue developed before the first century and became an important Jewish communal institution. Its functions could include assembly, instruction, communal affairs, prayer, and Scripture.
The Sabbath became especially associated with communal Torah study.
Residents of a village or town with a synagogue could gather there on the Sabbath. The gathering provided contact with neighbors and an opportunity to hear Scripture in a culture where many people did not personally own biblical scrolls.
First-century synagogue structures and inscriptions provide material evidence for Jewish communal assembly. Their architecture demonstrates that gathering and communal activity were important functions.
Ancient Jewish writings, inscriptions, and the New Testament associate synagogues with Sabbath assembly and instruction. Later sources describe more developed synagogue worship.
The synagogue is not established by the Torah in the same way as the Jerusalem Temple. Its development provided local communities with a setting for Scripture, instruction, prayer, and assembly.
Luke 4:16-21 describes Jesus entering the synagogue in Nazareth on the Sabbath and reading from Isaiah. Mark 1:21 and other passages likewise place Jesus teaching in synagogues on the Sabbath.
Synagogues existed in the first century, and Sabbath gatherings involving Scripture and teaching are well attested.
The precise order of worship and prayers probably varied, and later standardized synagogue liturgies cannot simply be assumed for every first-century congregation.
The synagogue provides the setting for several important Gospel episodes and helps explain how ordinary Jewish people encountered Scripture and religious teaching.
