“An Exchange of Gifts”: Benedict XVI’s Eucharistic Ecclesiology as an Approach to Ecumenism

Christian unity, or the “ecumenical movement,” is one of Joseph Ratzinger’s (turn Benedict XVI) most apparent apostolates during his Pontificate. His thought on the matter is a development of the theologies developed in the Second Vatican Council’s Lumen Gentium and John Paul II’s Ut Unum Sint, borrowing the words “exchange of gifts,” which affirms elements of sanctification present in churches “separated” from Rome. This work will expand on how Benedict XVI’s teachings about the Eucharist as the Sacrament of Unity gained merit in the Church’s ecumenical movement. This theology can be described as a “Eucharistic Ecclesiology,” and it has earlier codification made formal through the thought of Henri de Lubac. It will be done firstly through an exposition of de Lubac’s commentary in Mystici Corporis, which confirms the origins of Eucharistic Ecclesiology through Patristic and Pauline theology. Next is a look at Pope Benedict XVI’s interjection of this theology into his ecumenical thought with a particular emphasis on the essentialities of the ontological reality of the Church, the shared Christian traditions, and “spiritual ecumenism.” In the final discussions, we shall include a quick run through his Pontificate’s ecumenical initiatives where the teachings about Eucharistic Ecclesiology are dispersed in various circumstances.
