Guest speaker Russ Peterson continues the network values series with 'collaborative,' tracing the word to the Latin for working together and finding the pattern in Acts, where the temple-observant Jerusalem church and the multicultural Antioch church strengthen each other in both directions — Barnabas sent north, famine relief sent back. The Jerusalem Council then models how collaboration survives disagreement: much debate, then silence and listening, and finally shared ground rules the Spirit worked out among them.
