The apostle Paul addressed his fellow-laborers as synergos (pronounced "soon'-er-gös"), a Greek word he coined for the purpose —and from which we derive our English words, synergy and synergism.

synergism (siner jizem)n.
  1. the simultaneous action of separate agencies which, together, have greater total effect than the sum of their individual effects
  2. the combined or correlated action of different organs or parts of the body, as of muscles working together

1Peter 2:5

"...We teach everyone we can all that we know about Him, so that, if possible, we may bring every man up to his full maturity in Christ Jesus."
