The Incarnation is a mystery of the faith. A mystery is a truth that had to have been revealed by God, and whose depths we will never completely comprehend in this life. However, we cannot dismiss a mystery as incomprehensible, and go on our merry way, not giving it another thought. It is through contemplation of the mysteries that we come to know Christ. Therefore, it is the job of each and every mature Christian to contemplate each of the mysteries of the faith. In fact, Holy Mother Church won’t let us get away with not doing it. Which is why she gives us Advent and Christmas so that we will dwell in the mystery of the Incarnation.
When we first set out to contemplate the Incarnation, we begin to see it’s absurdity, it’s irony, the scandal that it causes in our minds and hearts. God becoming man, taking on a human nature in the womb of Mary, is an amazing event. If it doesn’t strike us as an awesome gift, then we are not seeing clearly God’s magnificence and our own insignificance.
Fulton Sheen expressed this paradox of the God-man in his book called Life of Christ:
No worldly mind would ever have suspected ---
THAT HE WHO COULD MAKE THE SUN WARM THE EARTH
Would one day have need of an ox and an ass to warm Him with their breath...
THAT HE, FROM WHOSE HANDS CAME PLANETS AND WORLDS,
Would one day have tiny arms that were not long enough to touch the huge heads of the cattle…
THAT THE ETERNAL WORD
Would be dumb;
Would be wrapped in swaddling clothes;
Would lie in a manger.
