The leader ship of the Church of the late first century and the early second century had to confront the issues associated with an expanding organization. Similar to the problems of growing business. As it enlarges and spreads across the Greco-Roman world, the bishops and leaders of the Church, which is in itself a new term, have to try to control problems arising in all of the different communities. They do so by establishing leaders in each parish that try to enforce the rules and life style of Christianity. The communal followings stay in contact with the larger Church by exchange of letters too.
In the excerpt of the Didache that we read, it seems that one of the larger problems that the Church is facing is the attempts of people to take advantages of communities by imitating prophets. People come into the village, pretend to be inspired by God, do false preaching, and then ask for money or other goods in return. To conflict this problem, the Church sent out letter to its followers trying to give advice in order to tell a false prophet from true prophet, and how to treat each accordingly. One example was that if the prophet asks for money upon leaving, he probably was just a thief. The problem with this type of recognition was that you could only discern a phony from a real prophet after you opened up your house or village to them, and treated them well. They basically already got what they wanted. In order to confront this, I believe the Church may have needed to place more bishops or deacons in proportion to the growing number of followers in order to help maintain order as the Church grew and became more organized over the centuries.
