Of all the ways of writing and of thinking about Europe covered in this study, David Jones's are most intimately and explicitly connected to one another. Owing largely to Jones's 1955 essay Art and Sacrament, the principle of sacramentalism, out of which all of Jones's poetry and, indeed, all of his creative art grows, has become a cornerstone of scholarship on Jones and his work. Jones's idea of Europe is summed up in the same words the European Union has chosen as its motto: United in Diversity. This chapter shows how Jones's religious ideas can be seen to interact with his idea of European identity. Keeping the islands adjacent, as well as the various deposits of Catholic culture in the landscape of In Parenthesis, are good, hard images for the concept of unity in diversity that Jones champions.
