Christ in the Eucharist
Many Christian churches holding to a doctrine of the Real Presence of Christ in the Eucharist (for example, Roman Catholics, Eastern Orthodox, Anglicans and Lutherans) require ordained clergy to officiate at the Eucharist, consecrating and distributing the elements to communicants.
In the view of these Churches, the presence of Christ in the Eucharist is of an order different from the presence of Christ in the other sacraments: in the other sacraments he is present by his power rather than by the reality of his body and blood, the basis of the expression “Real Presence”. Accordingly, they consider that those who hold that, in objective reality, the elements of the Eucharist remain unchanged believe not in the Real Presence of Christ in this particular sacrament, but in a presence that is merely personal to the communicant, whatever name (pneumatic, anamnetical, etc.) is used to describe it.
