Is worship the most important thing?

I came across this quote recently:

Is worship the most important thing our congregations do? I would say no at this point. Maybe that view will some day change, but the importance of congregations is bringing people together in relationship. Worship can be a mechanism of that function, and it is a fundamental element to the community. The greek terms for church life seem applicable, church is about leitourgia (worship), but also diakonia(service), koinonia(community), kerygma(proclamation), and didache(teaching). All of them are fundamental and none supercede the others.
