A church: sharing what we have in common
I was all into chiasms when I was studying (part time) in a seminary. I would always try to see if there were chiastic structures in the bible passages I studied. A chiasm is the figure of speech in which two or more clauses are related to each other through a reversal of structures in order to make a larger point; that is, the clauses display inverted parallelism.
So when today's sermon by Matthew Bellville began with a look into the chiastic structure Acts 2:41-47, I was quite enthused. The passage is about the early believers forming a community, a church. And with the chiastic structure, the focus of the passage is in v.44.
Acts 2:41-47 NLT
 Those who believed what Peter said
were baptized and added to the church
that day-about 3,000 in all.
 All the believers devoted
themselves to the apostles'
teaching, and to fellowship, and
to sharing in meals (including the
Lord's Supper), and to prayer.
 A deep sense of awe came over
them all, and the apostles
performed many miraculous signs
 And all the believers met
together in one place and
shared everything they had.
 They sold their property and
possessions and shared the money
with those in need.
 They worshiped together at the
Temple each day, met in homes for
the Lord's Supper, and shared their
meals with great joy and generosity-
 all the while praising God and
enjoying the goodwill of all the people.
And each day the Lord added to their
fellowship those who were being saved.
The speaker highlighted that there the original Greek in v.44 do not have the word "everything" in it and the more literal translation of "all in common" implies that they shared what they have in common, beyond the materialistic things. They shared what is common in their one faith, one Lord, one Ruler, one future, one hope, one law keeper.
πάντες δὲ οἱ πιστεύσαντες ἐπὶ
all moreover having believed (were) together
τὸ αὐτὸ εἶχον ἅπαντα κοινά.
the same having all in common.
And what they had been doing and what we should be doing in church and out of church are the four devotions we have in common as listed in v.42:
1. Apostolic teaching
3. Sharing of meals
4. Prayer, in hope and in confession
And with this, it lessens the emphasis we usually pay to v.45, where according to the NIV Study Bible, it is "not communalism or communism since this giving is voluntary (5:4) and since people still retain personal possessions like homes (12:12; 17:5) and property (4:37). A better analogy is that the church views itself as a family, and healthy families take care of their own."
I like the what it says of the church, "a family, and healthy families take care of their own."
