I’m enjoying reading an article by Nicholas Taylor in the Scottish Episcopal Institute Journal. I particularly enjoyed his reconstruction of how house churches eventually became congregations that were not just members from one family and the associated slaves or servants, and also of how the local house churches leaders eventually gave birth—early on—to having one house church elder with oversight over other congregations, which is to say a bishop:
It is clear that congregations were, or rapidly became, more than simply the household at worship. As well as itinerant Christian missionaries and other travellers who might temporarily attach themselves to a Christian congregation, and avail themselves of the hospitality of the householders, cities attracted disparate and displaced individuals who, for whatever reason, had temporarily or permanently lost their roots in the household to which they had belonged. If these were converted, they might have attached themselves to an existing church and household, or perhaps have formed a church of their own, apart from the patronage system of household and city. Churches may also have been formed of more than one household, particularly when a person of wealth and status was able to provide a degree of protection and access to Christian teaching not available to a poorer household.
It is precisely at the point at which a church moves beyond the parameters of the household that the emergence of distinctive, defined, and titled forms of hierarchy and ministry should be sought. The most powerful householder in a city or town, who would almost certainly have hosted gatherings of the church, either in his own home or in a public building rented for the purpose, would at this point have emerged as bishop.
