Abstract: Secular humanists in the United Kingdom regularly think about, talk about, and act in relation to religion, especially Christianity. In this article, I address the relationships between secular humanism and Christianity by drawing on fieldwork with a local humanist group affiliated with the British Humanist Association. In line with many moderns, as indeed with many kinds of Christians, these secular humanists often want to sever ties with the past—in this case, with what they understand to be Christianity’s religious elements. At the same time, they want to preserve those aspects of Christianity they understand to be human, not religious. These engagements with and articulations of Christianity can be helpful not only for understanding contemporary secular-humanist formations but also some of the debates that have framed the anthropology of Christianity over the past decade.
