The real presence of Christ in the Eucharist is a term used in Christian theology to express the doctrine that Jesus is really or substantially present in the Eucharist, not merely symbolically or metaphorically.
There are a number of different views in the understanding of the meaning of the term "reality" in this context between contemporary Christian confessions which accept it, including the Catholic Church, the Eastern Orthodox Church, Oriental Orthodoxy, the Church of the East, Lutheranism, Anglicanism and Methodism. These differences correspond to literal or figurative interpretations of Christ's Words of Institution, as well as questions related to the concept of realism in the context of the Platonic substance and accident. Efforts at mutual understanding of the range of beliefs by these Churches led in the 1980s to consultations on Baptism, Eucharist and Ministry through the World Council of Churches.
By contrast, the doctrine is rejected by Anabaptists.
Eucharistic theology as a branch of Christian theology developed during the medieval period; before that, during the early medieval period theological disputes had focussed mostly on questions of Christology.
An early debate on the question took place in the 9th century, after Charles the Bald had posed the question if the body and blood of Christ were to be a mystery of faith, or if they were truly present (in mysterio fiat an in veritate). Contrary positions were taken by Paschasius Radbertus and Ratramnus. Ratramnus held that the body of Christ was present spiritually (spiritualiter) but not physically (corporaliter), while Paschasius emphasized the true presence of the body of Christ. The dispute was resolved by Paschasius in a letter to Frudiger, in which he clarified his position to the effect that the true nature of the sacramental body of Christ is spiritual, so that the true presence of Christ's body is necessarily spiritual and not physical in nature, so that its presence in the Eucharist is real and symbolic at the same time.
