The Roman Catholic view of transubstantiation is the sacramental view that the elements of the Lord’s Supper are miraculously transformed into the literal body and blood of Christ by the priest’s consecration which is sacerdotalism. At the moment the priest says, “This is my body” the element becomes the literal body of Christ according to Catholicism. For centuries, the RCC did not allow lay people to drink from the cup, for fear that the blood of Christ would be spilled but Vatican II (1962-1965) changed this (Grudem, Systematic Theology, page 991).
