A priority for Protestants was to replace the Roman Catholic teaching that the Mass was a sacrifice to God ("the very same sacrifice as that of the cross") with the Protestant teaching that it was a service of thanksgiving and spiritual communion with Christ. Cranmer's intention was to suppress notions of sacrifice and transubstantiation in the Mass. To stress this, there was no elevation of the consecrated bread and wine, and eucharistic adoration was prohibited. The elevation had been the central moment of the medieval Mass, attached as it was to the idea of real presence. Cranmer's eucharistic theology was close to the Calvinist spiritual presence view and can be described as Receptionism and Virtualism: i.e. Christ is really present but by the power of the Holy Spirit. The words of administration in the 1549 rite were deliberately ambiguous; they could be understood as identifying the bread with the body of Christ or (following Cranmer's theology) as a prayer that the communicant might spiritually receive the body of Christ by faith.
