One of the subtleties of Shakespeare’s As You Like It is the existence of layers of sexual ambiguity implied in its original performance: a boy-actor played the part of a young woman disguised as a young man who at one point is pretending to be a girl. I was put in mind of these layers of meaning when I read The Eucharist: sacrament of unity (ESU), the Church of England’s highly courteous and careful response to the British and Irish bishops’ 1998 teaching document on eucharistic doctrine and sharing entitled One Bread One Body (OBOB). There is of course one vitally important difference: whereas the play’s layers form the stages in a dialectic, i.e. an interactive process, of ambiguity, the theological document offers a dialectic of clarification, which provides a model of what is involved in ecumenical reception.
