So what did “the church” look like, in practical terms? What set apart the Jewish disciples of Jesus in Jerusalem to distinguish them from the rest of the Jewish people?  “The Lord was adding to their number day by day those who were being saved”. What made “their number” distinct enough from the rest of the people that they might be recognized as a social unit that could be joined? It wasn’t the venue. They assembled in the Temple. It wasn’t their unique spirit-filled worship services; the worship services were liturgical functions led by the Levitical class. The thing that set the earliest church apart from the rest of the Jewish people was their table. They hosted meals for an exclusive table fellowship. - DT Lancaster, The Sacred Fellowship Meal
