had been lost within contemporary Roman Catholicism in the internationalism of centralised papal authority. Within the coming universal church that Maurice foresaw, national churches would each maintain the six signs of Catholicity: baptism, Eucharist, the creeds, Scripture, an episcopal ministry, and a fixed liturgy (which could take a variety of forms in accordance with divinely ordained distinctions in national characteristics). Not surprisingly, this vision of a becoming universal church as a congregation of autonomous national churches proved highly congenial in Anglican circles; and Maurice's six signs were adapted to form the Chicago-Lambeth Quadrilateral of 1888. In the latter decades of the 20th century, Maurice's theory, and the various strands of Anglican thought that derived from it, have been criticised by Stephen Sykes, who argues that the terms Protestant and Catholic as used in these approaches are synthetic constructs denoting ecclesiastic identities unacceptable to those to whom the labels are applied. Hence, the Catholic Church does not regard itself as a party or strand within the universal church – but rather identifies itself as the universal church. Moreover, Sykes criticises the proposition, implicit in theories of via media, that there is no distinctive body of Anglican doctrines, other than those of the universal church; accusing this of being an excuse not to undertake systematic doctrine at all. Contrariwise, Sykes notes a high degree of commonality in Anglican liturgical forms and in the doctrinal understandings expressed within those liturgies. He proposes that Anglican identity might rather be found within a shared consistent pattern of prescriptive liturgies, established and maintained through canon law, and embodying both a historic deposit of formal statements of doctrine, and also framing the regular reading and proclamation of scripture. Sykes nevertheless agrees with those heirs of Maurice who emphasise the incompleteness of Anglicanism as a positive feature, and quotes with qualified approval the words of Michael Ramsey: Doctrine "Catholic and reformed" The distinction between Reformed and Catholic, and the coherence of the two, is a matter of debate within the Anglican Communion. The Oxford Movement of the mid-19th century revived and extended doctrinal, liturgical, and pastoral practices similar to those of Roman Catholicism. This extends beyond the ceremony of high church services to even more theologically significant territory, such as sacramental theology (see Anglican sacraments). While Anglo-Catholic practices, particularly liturgical ones, have become more common within the tradition over the last century, there are also places where practices
