Anti-Catholicism is part of the dynamics of Northern Ireland's conflict and
is critical to the self-defining identity of certain Protestants. However,
anti-Catholicism is as much a sociological process as a theological disput
e about doctrine. It was given a Scriptural underpinning in the history of
Protestant-Catholic relations in Ireland, and wider British-Irish relations
, in order to reinforce social divisions between the religious communities
and to offer a deterministic belief system to justify them. This article ex
amines the socio-economic and political processes that have led to theology
being used in social closure and stratification. It describes the various
forms of contemporary anti-Catholicism, and highlights two further sociolog
ical features of the process, the common-sense reasoning process which repr
oduces it and how, in its language, it operates as a 'discursive formation'
.
