I fear for the life of Pope Benedict.
It is scripturally based doctrine that the risen Christ is present body, blood, soul, and Divinity in the Holy Eucharist. You simply cannot theologically and coherently believe in one and not the other. The Resurrection and the Eucharist are twin concepts. To deny the true presence of Christ in the Eucharist, is to deny the truth of his Resurrection. To deny the truth of the Resurrection is to be a heretic.
Despite all the exegetical treatises on the truth of the Resurrection, it is all reduced to complete pablum if one at the same denies the true presence of the risen Christ in the Eucharist.
It is flatly against Catholic teaching of two millennia that those who do not share this central belief be administered Holy Communion. This would be drinking judgment unto itself. Unforgivable.
