Where are these "Missionary/Evangelist teams" in a Scripture that talks only of Bishops, Presbyters (Priests - look up the derivation), and Deacons?
Paul/Barnabas/Silas/John Mark ?
How could this not be a comprehensive picture of Christ? Are you claiming their preaching was lacking?
I think that their preaching was entirely adequate.
Do you think the average first century christian's picture of Christ was as comprehensive as that which is available to us today through the completed canon of scripture ?
The average first century Christian could talk to (or at least hear from) an actual witness to Christ's life and resurrection. Ponder that for a moment.
