It is a thing indeed that the angels do not have, or at least, that we do not share with the angels in the same way. It is brought on by the intimacy which we can have with the Saviour, all the more greater intimacy because of the incarnation which is prolonged in the Eucharist. The poor angels!
They do not have the Holy Communion, the Holy Angels themselves! Admittedly, those which remained faithful - they did not succumb to the temptation of jealousy - now have the happiness of seeing their Creator. That is enough to give them an inalterable joy. Consequently, they do not have any reason to be jealous of us. And it is well thus, because we could, nevertheless, provide them other occasions for which they could envy us. What do we thus have that they do not have?
The great St. Francis de Sales has given us an answer: "If jealousy could penetrate the kingdom of the eternal love, the angels would envy the sufferings of God for man and those of man for God"
Ah, truly! We, poor fellows, will never comprehend well to what degree we are blessed!
