Today, while pondering over the Transfiguration, we can sense man situation in Heaven. What interest us the most is to consider the spontaneous reaction of those "earthly partners" of that scene. Once again, is Simon Peter who takes the floor: "Master, it is good for us to be here" (Lk 9:33). It is wonderful to see that, only by looking at the body of Christ in a glorious mood, Peter feels fully happy: he does not miss anything else
"Let us put up three shelters, one for you, one for Moses and one for Elijah." Peter’s reaction shows the truest dynamism of love: he thinks no more of his own comfort; he wants to save that level of deep joy, by seeking the good of others (in this case, by interpreting it in a very human way: some shelters!). It is the clearest manifestation of true love: I am happy because I make you happy; I am happy by offering me to your happiness.
Besides, the fact that Simon intuitively recognizes Moses and Elijah is very revealing. Peter, logically, knew about them, but had never seen them (they had lived centuries earlier!) but, instead, he identifies them immediately (as if he had always known them). Here is a sample of the high degree of knowledge of man in Heaven: when looking at God "face to face", man will experience an unimaginable expansion of his knowledge (a much more profound participation in the Truth). Finally, «"divinization" in the other world will bring to the human spirit “such a range of experience of truth and love such as man would never have been able to attain in earthly life» (St. John Paul II).
Finally, Simon, when seeing Moses and Elijah, not only accepts them instantly, but also loves them immediately (he thinks of putting up a shelter for each one of them). St. Peter, Pope (the first one of the Church), but also a fisherman, expresses his love in a simple way; St. Teresa, nun, but Doctor (of the Church) expressed the logic of love in a profound way: «the contentment of pleasing the other exceeds my own contentment».
