The twelve (or Twelve) are still together at this point, so we are dealing a very early episode here.

Not long before, Jesus had washed the feet of these men, a task normally reserved for slaves (called servants in most translations). He ate dinner with them that same night, sharing bread and wine with them. Some of His last words were to Peter, the leader of the Twelve, "Feed my sheep."

Now, so soon, the twelve are not to be bothered with providing simple justice to widows and orphans. They either don't see the injustice being committed under their governance or they don't consider it an injustice to short the non-Jews in their numbers.

Now, caring for widows and orphans is not just a new rule that Jesus initiated, it is a central tenet of Judaism. They are not just not following their risen Lord, they are not following the Law and the Prophets.

Now at this point, we are not dealing with a CHURCH, but with a small movement. By appointing others to deal with this problem so early, the twelve sent a message. The leaders are, to some extent, exempt from the need to actually practice what they preach.

Of course, these twelve men will go forth to preach the Word and will die for it. Still, it is striking that they abandon service / submission as the core of their faith and start on the road of hierarchy.

BTW, I am a member of a very high church parish, but even I can see the disconnect here.
