-First, they devoted themselves to the teaching of the apostles
The apostles are witnesses passing along the things which they have seen and heard. It is entirely possible that the apostles had common set of instruction which they regularly passed along to new converts. If this is the case, then there was a basic body of tradition within months of the death of Jesus which could be called the “teaching of the apostles.”
-Second, they devoted themselves to fellowship (κοινωνία). Since this word has the connotation of sharing common,
I would suggest that many of those who needed assistance were Diaspora pilgrims who accepted the message of Jesus and remained in Jerusalem rather than to return home after Pentecost.
-Third, they devoted themselves to “breaking of bread.” While this phrase can be used of sharing a meal together, it is likely that Luke is describing the community as celebrating some form of communion. Jesus breaking bread as two disciples realized who he was. I think that Jesus’ practice of common meals was the foundation for this practice they all ate and drank together as one group.
-Fourth, they devoted themselves to prayers. Since the Greek is plural this is plausibly a reference to daily prayers in the Temple. It would not be unusual for Jewish men to go to the Temple several times a day to pray, so the community continues to worship at the Temple regularly. This likely put them into contact with other observant Jews who would then be introduced to Jesus as Messiah.
