The connection between Christianity and the development of Western welfare states is long-standing, albeit somewhat neglected by scholarship. Recent work has suggested the formative influence on the formation of different welfare "regimes" through different Christian ideas of work, need, poverty, and the family, as well as differnt ecclesiologies. The chapter outlines these and proceeds to examine the philsophical connection between social welfare and religion, through the work of Raymond Plant. Plant argues that welfare policy invariably draws on inherently "contestable" social concepts, such as ‘need’, ‘want’, ‘right’, ‘justice’, ‘equality’, and ‘community’. To know what kind of good social policy is pursuing, it is essential to clarify what meaning and weight we accord to such concepts. But doing this demands we have a clear idea of the kind of creatures whose goods we are pursuing. In essence, social welfare theory of this kind rests on anthropological commitments. The chapter illustrates this by reference to Richard Titmuss, Margaret Thatcher, and Frank Field, and in so doing, underlines how this entire debate is open to theological perspectives.
