Flip, THis is how I always understood it.
w04 3/1 p. 11 par. 15 A “Slave” Who Is Both Faithful and Discreet
15 The fundamental spiritual food given in the first century proceeded directly from the pens of the apostles and other disciples who were taking the lead. The letters they wrote—especially those found among the 27 inspired books that make up the Christian Greek Scriptures—were circulated among the congregations and without doubt provided the basis for teaching by the local elders. In this way, representatives of the slave faithfully distributed rich spiritual food to sincere Christians. The first-century slave class proved faithful to its commission.*** w75 1/15 pp. 46-47 How Are Christians Spiritually Fed? ***
Someone may ask, ‘How can the "slave," who is composed of the "domestics," feed the "domestics"? That would amount to the "slave" feeding itself.' This might be illustrated by a family that moves to a farm. One of their first needs is provision for food. Does the father provide all the food and put it into the mouths of the rest? No. Each family member performs a different task. One may do the plowing. Others may work to dig a well. Some engage in planting. Some take care of the cattle and the dairy. Of course, all may help in certain features of the work. Likely all would engage in the harvest. Then, the women would do canning for future feeding. They would cook and serve the food to the family. Now, no one individual could have provided so well. But with family effort, all are well fed. As a family they are one body, just as the "faithful and discreet slave." But as individuals they are workers in producing and serving food, as "domestics" in a household. A similar illustration given by the apostle Paul at 1 Corinthians 12:12-27 is that of a physical human body and its members.
This is how I remember it Flip. There were different aspects of the FDS. Not all were info providers, only those who served as "apostles" and not the grunts in the field. The idea of all FDS members writing the society with "New Light" was an urban myth as far as I knew, (A STRONG ONE THOUGH). What WT said they all provided information to be sorted out and published? I never read that. Not meaning to be obstinante or prove I'm right, I'm just showing why I never had that understanding. Of course I could have misunderstood.
That was a subject that always bothered me. Why didn't they all have a part? This is the answer I found while studying it years ago. Peace out, Flipper respecter. W.Once
