Umm, you know that many Protestants perfectly well understand the significance of Christ's real presence in the Eucharist. It's upon other matters of faith which they disagree with the Catholic Church. But precisely because we disagree on some important matters we should seek administration of the Sacraments from someone ordained in our own faith, excepting only in instances of grave emergency. (imminent participation in mortal combat for a just cause is just such an emergency, in my opinion)
I agree with you - even between us, consubstantiation and transubstantiation are two entirely different things although similar in some respects.
I think some of the words in the answer provided by the pope are direct and others can be played with... and are played with by quite a few of the ordained who should know better.
Not sure what exactly I am trying to say here but it's something like, just like everything else, we have gotten to the point where 'no' is taken as a personal insult and an opportunity to be the victim of prejudice of some sort or other (sit on the back of the bus).
Now, in the case of imminent danger (war) there may be a soul who does believe in what the Catholic Church teaches and would have converted if he had more time. In that scenerio, of course he would want to receive the Body and Blood of Jesus Christ and confess his sins to an ordained Catholic priest.
