Ingrown churches

Many of our churches are focused on one personality. One pastor occupies the pulpit on Sundays and Wednesdays. We hear one perspective. While I understand the need for unity of command and a pastor who jealously guards his pulpit, this can become a problem. Diptrophes would not allow others to speak in his church and the Apostle John rebuked him for it (3Jo 1:9-10). The early church was less closed and less ingrown. John was preventing the evolution of a cult by demanding cross-pollination. Our churches should not be focused on a personality, but on the truth. We should all be familiar enough with the Scriptures that we can critically evaluate each message and correct any false teaching (Act 17:11). This might help our churches become more outwardly focused and less defensive.
