“He remained what he was; he took up what he was not…to make possible the kind of remedy that fitted our human need.”
On the feast day of our Lady of Mount Carmel (July 15), one of the main themes in the second reading of the Office of Readings of the Liturgy of the Hours focuses on the reality of the Second Person of the Holy Trinity assuming a human nature so that while remaining fully divine, He is also fully human in nature. Pope Saint Leo the Great writes, “He remained what he was; he took up what he was not. He wanted to join the very nature of a servant to that nature in which he is equal to God the Father. He wanted to unite both natures in an alliance so wonderful that the glory of the greater would not annihilate the lesser, nor the taking up of the lower diminish the greatness of the higher. What belongs to each nature is preserved intact and meets the other in one person: lowliness is taken up by greatness, weakness by power, mortality by eternity. To pay the debt of our human condition, a nature incapable of suffering is united to a nature capable of suffering, and true God and true man are forged into the unity that is the Lord. This was done to make possible the kind of remedy that fitted our human need: one and the same mediator between God and men able to die because of one nature, able to rise again because of the other.”1 This person is the Word.
And why? Pope Saint Leo the Great gives us the answer as he writes: “this kind of birth was fitting for Christ, the power and the wisdom of God: a birth in which he was one with us in our human nature but far above us in his divinity. If he were not true God, he would not be able to bring us healing, if he were not true man, he would not be able to give us an example.”2 It is through His sacred humanity that the Lord provides the way to be united to Him and to be taken up with Him to the Father.
This “remedy” is the divine life that begins in us through Baptism. Among the gifts of the Sacrament of Baptism, we receive the indwelling of the Holy Trinity and sanctifying grace, the seeds of eternal life. We are baptized into Christ, and, as members of His Body, we are united to Him and able to offer worship to the Father.
From a sermon of Saint Leo the Great, pope
Mary conceived in her soul before she conceived in her body
A royal virgin of the house of David is chosen. She is to bear a holy child, one who is both God and man. She is to conceive him in her soul before she conceives him in her body. In the face of so unheard of an event she is to know no fear through ignorance of the divine plan; the angel tells her what is to be accomplished in her by the Holy Spirit. She believes that there will be no loss of virginity, she who is soon to be the mother of God. Why should she lose heart at this new form of conceiving when she has been promised that it will be effected through the power of the Most High? She believes, and her faith is confirmed by the witness of a previous wonder: against all expectation Elizabeth is made fruitful. God has enabled a barren woman to be with child; he must be believed when he makes the same promise to a virgin.
The Son of God who was in the beginning with God, through whom all things were made, without whom nothing was made, became man to free him from eternal death. He stooped down to take up our lowliness without loss to his own glory. He remained what he was; he took up what he was not. He wanted to join the very nature of a servant to that nature in which he is equal to God the Father. He wanted to unite both natures in an alliance so wonderful that the glory of the greater would not annihilate the lesser, nor the taking up of the lower diminish the greatness of the higher.
What belongs to each nature is preserved intact and meets the other in one person: lowliness is taken up by greatness, weakness by power, mortality by eternity. To pay the debt of our human condition, a nature incapable of suffering is united to a nature capable of suffering, and true God and true man are forged into the unity that is the Lord. This was done to make possible the kind of remedy that fitted our human need: one and the same mediator between God and men able to die because of one nature, able to rise again because of the other. It was fitting, therefore, that the birth which brings salvation brought no corruption to virginal integrity; the bringing forth of Truth was at the same time the safeguarding of virginity.
Dearly beloved, this kind of birth was fitting for Christ, the power and the wisdom of God: a birth in which he was one with us in our human nature but far above us in his divinity. If he were not true God, he would not be able to bring us healing, if he were not true man, he would not be able to give us an example.
And so at the birth of our Lord, the angels sing in joy: Glory to God in the highest, and they proclaim peace to his people on earth as they see the heavenly Jerusalem being built from all the nations of the world. If the angels on high are so exultant at this marvelous work of God’s goodness, what joy should it not bring to the lowly hearts of men?
