In a beautiful essay on the Eucharist, written in 1916 during the First World War, Teilhard de Chardin gives us the fruit of a meditation made in front of the Blessed Sacrament. Entitled "The Monstrance," the essay describes how, while kneeling in prayer, a person (probably the author himself) suddenly had the sensation that the Host began "to expand and grow bigger". The white Host soon enveloped not only the one in prayer but all reality as it continued to grow. Soon "through the mysterious expansion of the Host the whole world had become incandescent, had itself become like a single giant Host... It had penetrated, through the channels of matter, into the inmost depths of all hearts and had dilated them to breaking point, only in order to take back into itself the substance of their affections and passions. (Hymn of the Universe)

It is truly a magnificent picture, revealing in graphic form the power of the Eucharistic Lord to reach out and embrace and transform all things. It is, moreover, a perception of a great truth and one that corrects the unreflecting accusation made at times by those who have little experience of the true nature of Eucharistic adoration. For it has frequently been said that the Eucharist has been given to us as our food, not (at least not primarily) to be adored, and that adoration in a silent church or before a monstrance is a devotion that flows from a "static" view of the Eucharist, one, that is, that emphasizes the Lord's Presence as opposed to his action of self-giving or sacrificial self-surrender, etc... What Teilhard's reflection indicates is that the very Presence of Christ is always dynamic, is indeed the very font of endless, though invisible, activity. Lifted up, he draws all things to himself (cf. Jn 12:32).
