But Paul knew something of it: for he was caught up alive into the Third Heaven, and into Paradise.[463] Yet instead of satisfying our curiosity, he tells us that it would be impossible to do so, for that he heard unspeakable words which it is not lawful for a num to utter. We are thus positively forbidden to pry into the matter: but we are at least permitted to infer that what Paul saw was transcendently beautiful, full of such ravishing joy as we cannot now conceive. For, when he returned to earth, he was so elated by what he had experienced, so thoroughly unstrung for this lower life by his short taste of that which is to come, that he would have been incapacitated for further service in this world had not God brought him down to his former level by a painful affliction, a thorn in the flesh, a messenger of Satan sent to buffet him. It was, therefore, no Purgatory which Paul saw—he would not have needed a thorn in the flesh to keep him from elation after such a sight as that—but a Paradise of beauty and joy far beyond the comprehension of man.
