The question of sacrifice in the Eucharist has been called by the Ways of Worship Commission of Faith and Order a ‘live issue’, that is to say a question over which agreement is not right out of sight though considerable and even vehement controversy continues. At Lund, the section considering Ways of Worship reported that they had held a lively and rewarding discussion on the subject, and had been surprised by the degree of agreement revealed; on the other hand it must be admitted that neither the discussion nor the resulting agreement are very apparent from the relevant chapter of the Conference report. This article is an attempt to examine the present state of the question against a background of ecumenical discussion, and to suggest ways of conceiving the Eucharistic Sacrifice which might be more widely acceptable than those commonly put forward by ‘catholics’ in the past. Its sources, besides a necessarily incomplete study of some of the more influential modern contributions to the discussion, consist mainly in discussions amongst younger theologians and theological students in the ecumenical movement. Whilst this group is not so learned as its elders, and its discussions are seldom recorded in print, its contribution can be a valuable one, because it is most sensitive to the issues which are now live ones, and also because it frequently seems to clear away misunderstandings more effectively and reach greater agreement than more senior groups.
