The New Testament speaks often of Jesus and the Apostles visiting various synagogues, but the synagogue is not mentioned in the Old Testament. Isn't that strange that a major facet of Jewish life in the New Testament doesn't get any (clear) mention in the Old Testament? This got me thinking about the origins and meaning of the Synagogue.
The various encyclopedias that I've come across say the synagogue originated around the time of the Babylonian Exile (600BC). Thus, while the term "synagogue" (and "church") literally means a gathering or assembly, the term synagogue referring to a "house of worship" (as we now think of it) didn't come around until 800 years after the Israelites left Egypt (1400BC). The Catholic Encyclopedia says on Synagogue:
It was probably during the Babylonian captivity that the synagogue became a national feature of Hebrew worship. Afar from their Temple, the exiled Jews gathered into local meeting-houses for public worship. Sacrifice was denied them; prayer in common was not. The longer their exile from the national altar of sacrifice, the greater became their need of houses of prayer; this need was met by an ever-increasing number of synagogues, scattered throughout the land of exile. From Babylonia this national system of synagogue worship was brought to Jerusalem. That the synagogue dates many generations earlier than Apostolic times, is clear from the authority of St. James: "For Moses [the Torah] has been proclaimed in every city since ancient times and is read in the synagogues on every Sabbath" (Acts 15:21).
The Mosaic Law foresaw the Israelites worshiping through a Sacrificial Priesthood, which after arriving in the Promise Land became centered in Jerusalem at the Temple (Jn 4:19-21; Jn 12:20; Acts 8:27; 24:11; Rev 11:1). Sacrifices are a prominent theme from the earliest pages of Genesis, and sacrificing to God was a central theme in letting the Israelites go free from Egypt (Ex 8:25-29 - 1400BC). Even coming back from the Babylonian Exile (530BC) had prioritized getting the Temple back up and running as soon as possible, and the Feast of the Dedication (Hanukkah) was about re-consecrating the Temple just 150 years prior to Jesus. So to just stop sacrificing is not really optional, and in fact it is a serious deformation of the Israelite religion to not have sacrifices going on (e.g. the book of Leviticus is dedicated to priestly sacrifices). Since the synagogue system was never about sacrifices this would strongly suggest it is not an actual (nor approved) replacement of sorts for the Temple sacrifices. The fact that during the ministry of Jesus the Temple sacrifices were going on at the same time as synagogue attendance even more strongly indicates they are not the same in the (ancient) Jewish mind (John 18:20; Acts 24:12). This realization, namely the the Synagogue is clearly distinct from the Temple, has serious ramifications for how we as Catholics (and Orthodox) view both the Jews and Protestants.
