Trapeza is the ordinary Greek word for a table, built from four feet. But in the first century the word already carried an economic charge. The money-changers Yeshua overturned worked at trapezai (Matthew 21:12). The banker who should have paid interest in the parable is literally the trapeza (Luke 19:23). A table was where value changed hands, which makes it the exact right word for what the Jerusalem assembly built.

Acts 6 describes the daily diakonia of the trapeza, the table-service by which pooled resources were issued to widows according to need. When the Greek-speaking widows were shorted, the assembly did not preach at the problem. It appointed seven men over the tables, staffed from the aggrieved population, and the system kept running for centuries, long enough that the emperor Julian complained he could not compete with it. The trapeza is where the movement's theology became measurable: covenant loyalty you can audit, mercy with intake and issue and an escalation path. A community's real confession is written at its tables.
