Hi friends. One other aspect of synagogue life was the role of the young people. They could publicly read from the scriptures at age 12. Imagine what a confidence builder that occasion would have been! As God's living truth was proclaimed and the older ones said their "amens".
Remember, the "not failing to assemble" is immediately followed by "but encourage one another". Those who participated were blessed. As were those who listened.
Some have painted the early Christians as illiterates... But Timothy from a child had known the scriptures. And history teaches us that the Jews were highly literate.
Some also have attacked the traditional church as being non-participatory. There is merit in such criticism and reform is needed. But in fairness, most churches have what is called Sunday School where virtually everyone is welcome to contribute and the vast majority of teachers love it when they do. As most "preachers" are delighted when there is a special song sung or a testimony given. (I can only speak here from my own experience which is indeed limited. There are no doubt certain pastors who are jealous of their microphone and their pulpit.)
The meetings described in 1 Corinthians were not completely open to everyone on every occasion. "Let two or three prophets or tongue-speakers...".
In the early days of Christianity there were obviously no newspapers, radio, TV, internet or telephones. Most lived in small apartments. The synagogue met their social needs in many ways which we cannot imagine. So yes Dan, it is interesting that the word synagogue encompasses the idea of hospitality.
