The Doctrine of Transubstantiation in Durand's Rationale

Abstract

In a recent article on the medieval dogma of transubstantiation, Gary Macy builds upon the works of Hans Jorissen and James F. McCue to question the validity of Jaroslav Pelikan's claim that “at the Fourth Lateran Council in 1215, the doctrine of the real presence of the body and blood of Christ in the Eucharist achieved its definitive formulation in the dogma of transubstantiation.” Macy demonstrates that through most of the thirteenth century, the majority of theologians did not, in fact, consider Lateran IV's decree the final word on eucharistic theology. The debate over precisely how the real presence of Christ occurred in the eucharist was far from closed.
