If the Church were to change its rules on shared Eucharistic Communion it would “go against Revelation and the Magisterium”, leading Christians to “commit blasphemy and sacrilege,” an Italian theologian has warned.

Drawing on the Church’s teaching based on Sacred Scripture and Tradition, Msgr. Nicola Bux, a former consulter to the Congregation for the Doctrine of the Faith, stressed that non-Catholic Christians must have undertaken baptism and confirmation in the Catholic Church, and repented of grave sin through sacramental confession, in order to be able to receive Jesus in the Eucharist.

Msgr. Bux was responding to the Register about concerns that elements of the current pontificate might be sympathetic of a form of “open Communion” proposed by the German Protestant theologian, Jürgen Moltmann.

The concerns have arisen primarily due to the Holy Father’s own comments on Holy Communion and Lutherans, his apparent support for some remarried divorcees to receive Holy Communion, and how others have used his frequently repeated maximabout the Eucharist: that it is “not a prize for the perfect, but a powerful medicine and nourishment for the weak.”

The debate specifically over intercommunion with Christian denominations follows recent remarks by Cardinal Walter Kasper who, in a Dec. 10 interview with Avvenire, said he hopes Pope Francis’ next declaration will open the way for intercommunion with other denominations “in special cases.”  

The German theologian said shared Eucharistic communion is just a matter of time, and that the Pope’s recent participation in the Reformation commemoration in Lund has given “a new thrust” to the “ecumenical process.”

Pope Francis has often expressed his admiration for Cardinal Kasper’s theology whose thinking has significantly influenced — and continues to influence — the priorities of this pontificate, particularly on the Eucharist. 

For Moltmann, Holy Communion is “the Lord's supper, not something organized by a church or a denomination”. He believes the Church “owes its life to the Lord and its fellowship to his supper, not the other way around” and so its invitation “goes out to all whom he is sent to invite.”
