In his little work, Eucharistic Participation: The Reconfiguration of Time and Space, Dutch-Canadian theologian Hans Boersma presents two essays that address the relationship between the Eucharist and time and space. In doing so, Boersma argues for a participatory understanding of the Eucharist as opposed to non-participatory views. That is, Boersma affirms that Christians genuinely participate in divine realities when eating the bread and wine (read: body and blood) in the Eucharist.
In his first chapter, Boersma argues for a sacramental understanding of time and sacrifice wherein past, present, and future are not understood to be utterly linear and disjunctive moments, but rather overlapping layers of temporal reality that are able to be brought up into the eternal life of God. Boersma utilizes the binding of Isaac, the crucifixion of Christ, and the Eucharist as the primary example for how three events are able to be genuinely connected in such a way that when Christians partake in the Eucharist, they are participating in the sacrifice of the cross. Since the Eucharist is bound to the cross of Christ, it is essentially sacrificial in meaning. It is important to note that this sacrificial meaning is not in disjunction with or in addition to the sacrifice of the cross; rather, the sacrificial meaning of the Eucharist and the participation believers have with that sacrificial meaning is part and parcel of the ultimate sacrifice in the cross of Christ.
The second chapter focuses on the spatial dimension of the Eucharist by asking how the materials of the bread and wine actually transform into the body and blood of Christ. Boersma appeals to Gregory of Nyssa’s understanding of this process, which is significant for largely two reasons: 1) Gregory focuses less on the transformation of the materials and more on the transformation of the believers who partake in the meal; 2) Gregory never actually outlines an explanation for how the elements transform, they simply due by virtue of Jesus’s promise and the invocation of the Holy Spirit. The latter point is especially important for Boersma who argues that the technical arguments concerning the nature of the transformation of the elements (e.g., transubstantiation, consubstantiation, etc.) are ultimately rationalistic attempts to explain an ultimately mysterious reality. Despite this claim, Boersma does think transubstantiation is a dangerous proposal, and all non-participatory views are unsatisfactory.
In sum, Boersma argues for a participatory understanding of the Eucharist wherein believers genuinely participate in and have union with the risen and ascended Christ by the power of the Holy Spirit. This Eucharistic participation is vital to the very essence and life of the church, which is the body and bride of Christ.
Criticisms are light due to the introductory nature of the book; it is only 72 pages long, and so its content is meant for those who are just learning these concepts. Nonetheless, there are two main issues with Boersma’s treatment. 1) the appeal to the Great Tradition is always problematic for several reasons we won’t get into here, but Boersma does so in a few places in this work. 2) Boersma’s understanding of participation is obviously influenced by Neoplatonic metaphysics, which when used by Boersma in this context can have a dangerous tendency to neglect the historical aspect of God’s creation and providence. Boersma, however, does seem to provide means for a genuine historical trajectory in the meaning of Christ’s sacrifice by appealing to the Holy Spirit, but Boersma does not provide enough elaboration on this point to provide explicit defense of the development of signs in redemptive history. To state the criticism concisely: an overly Platonic metaphysic as the foundation for how signs participate in the signified cannot account for the historical development of signs, which the latter is often accounted for by means of invoking typology. The ultimate danger for Boersma’s proposal is an eternal crucifixion in which all earthly, historical signs participate in with no redemptive historical trajectory.
In the end, a participatory understanding of the Eucharist is good and valuable, but Boersma’s proposal contains elements that may not be as valuable as others. In short, his conclusion is laudable, but the means by which he gets there may need to be revisited.
