In 1972 the URC came into being and two denominational traditions collided. There are problems today that are caused not by the positions regarding wider traditions, these were both traditions dominated by the Reformed Tradition, but by the fact that the two traditions did not bother to find out how the other tradition worked, the Presbyterian assumed that with these sort of half toned Congregationalists they would find it easy to dominate, the Congregationalists assumed that they would continue doing things as they always did with a few adjustments for Presbyterians as they had done before. The Presbyterians assumed there was a meeting two dissenting traditions of which theirs was superior because it was articulated. The Congregationalists just assumed the way they did things was the way it was to be done noy because it was Congregational but because that was how it was.
The mistake was made in thinking that within English Congretationalism there was a named tradition that in some way is comparable to the Presbyterian tradition of the Presbyterian Church of England. This Presbyterian tradition is that of a clear dissenting tradition that stands against the mainstream. It says “We do this BECAUSE we are PRESBYTERIAN”. It is clear and defined. English Congregationalism on the whole found no need for such a tradition. Indeed may have found problems with having it. Rather with respect to tradition it relates as a dominant discourse, the tradition has no name (or rarely is named) but is referenced by how “We do it”.
I suspect that this has several roots. Firstly the obvious one, the tradition is not a single strand but a loosely woven rope of many strands that are not always compatible. It is true that the Reformed strand is the core one but there are plenty of other bits. It has to be seen as an grouping that specialises in bringing the disparate together. What is more with the Independent part, for most congregations “the tradition” is primarily the tradition of that congregation and only secondarily draws on the wider experience of other congregations and the wider church. When you talk about the wider context few members have any interest. Thus there is a need to have a way of talking and holding things together without setting people’s backs up. Names tend to carry baggage with them, so it is convenient if their is no name for anyone to object to.
Secondly in England there was an indicator name change I suspect at the end of the nineteenth Century. Before that all Congregational churches tended to be called Independent and Congregational used only after then. Traditions are conservative by nature, I suspect that there is a strong streek of people who still think of themselves as going to the Independent Chapel despite this. To add to this the change seems to coincide with the NonConformist Ascendancy in Late Victorian times. There were places in England where Congregationalism was the dominant tradition, so naturally it took the dominant form.
The result is that former English Congregationalists are not concious of their Congregational heritage but they are secure in it, assuming it is the way things ought to be done by any rational person. They have not had a name and feel no need for a name. For them the question was how the Presbyterians will alter the way we do things. It is a tradition based around absorbing not fracturing.
The former Presbyterians, as do former Congregational Church of Scotland, (I have not idea what former Churches of Christ do) find that what happens is that instead of their nice named dissenting tradition, they are faced with a nameless mesh of ideas that somehow resists their attempts to say what it should be like. What is worse it uses the first person plural “We” of itself so your choice is to join it or dissent from belonging. This is not tradition as they know it, yet it assumes the dominant position.
