In 1534, William Tyndale had published his translation.  For the first time in English, in a translation directly from the Greek, Tyndale writes in I Corinthians 3,

What is Paul?  What thing is Apollos?  Only ministers . . .  

In the margin, Tyndale then explains, “The apostles and prelates are servants to preach Christ unto which doctrine only ought all obedience to be given.”

When the hierarchical status is emphasized and doctrine is downplayed, we have problems.  The external unity becomes a farce.
