Today's meditation: an ever new mystery

The Word of God was generated according to the flesh once and for all. Now, for his kindness to man, he ardently desires to be born according to the spirit in those who want him and becomes a child who grows with the growth of their virtues. It manifests itself to the extent it knows who receives it. It does not restrict the immense view of its greatness out of envy and jealousy, but wise, almost measuring it, the ability of those who wish to see it. Thus the Word of God, while manifesting itself in the measure of those who participate in it, nevertheless remains always inscrutable to all, given the height of the mystery. For this reason, the Apostle of God, knowingly considering the extent of the mystery, says: "Jesus Christ is the same yesterday, today and always!" (Heb 13,8), meaning in this way that the mystery is always new and never grows old from the understanding of any human mind.
Christ God is born and becomes man, taking a body endowed with an intelligent soul, he, who had allowed things to come out of nowhere. From the east a star that shines in broad daylight guides the Magi to the place where the Word took flesh, to prove mystically that the Word contained in the law and the prophets surpasses all knowledge of the senses and leads people to the supreme light of knowledge.
In fact the word of the law and the prophets, like a star, rightly understood, leads to recognize the Incarnate Word those who by virtue of grace have been called according to the divine approval.
God becomes perfect man, by not changing anything that is proper to human nature, taken away, we mean sin, which, moreover, does not belong to it. He becomes man to provoke the hellish dragon greedy and impatient to devour his prey, that is, the humanity of Christ. Christ actually feeds his flesh on him. But that flesh was to be transformed into poison for the devil. The flesh totally destroyed the monster with the power of the divinity that was hidden in it. For human nature, however, it would have been the remedy, because it would have brought it back to original grace with the strength of the divinity present in it.
Just as the dragon, having instilled his poison in the tree of science, had ruined mankind, making him taste it, so the same, presuming to devour the flesh of the Lord, was ruined and ousted by the power of the divinity that was in it.
But the great mystery of the divine incarnation still remains a mystery. Indeed how can the Word, which with its person is essentially in the flesh, be at the same time as a person and essentially all in the Father? So how can the Word himself, totally God by nature, become totally man by nature? And this without abdicating at all neither to the divine nature, for which it is God, nor to ours, for which he became man?
Only faith comes to these mysteries, which is the substance and basis of those things which surpass all understanding of the human mind.
