The eternal Father had already determined to save man, who was lost through sin, and free him from eternal death. But because he wished that, at the same time, his divine justice should not be defrauded of a full and due satisfaction, he did not spare the life of his own Son, already made man in order to redeem man; but he required that he should pay, to its most rigorous extent, the penalty merited by men: “He that spared not even his own Son,” says the apostle, “but delivered him up for us all.”[1235] He sent him therefore on the earth to become man, destined for him a mother, and chose the Virgin Mary; but as he did not wish his divine Word to become her Son before she accepted him by her express consent, so he did not wish that Jesus should sacrifice his life for the salvation of men without the concurrence of the consent of Mary, that together with the sacrifice of the life of the Son, the heart of the mother might be sacrificed also. St. Thomas teaches, that the relation of mother gives an especial right over her children; hence Jesus, being innocent in himself and not deserving any punishment for his own sins, it seemed fitting that he should not be destined to the cross as the victim for the sins of the world without the consent of his mother, by which she should voluntarily offer him to death. But although Mary, from the moment she was made mother of Jesus, gave her consent to his death, yet the Lord wished her, on this day, to make, in the temple, a solemn sacrifice of herself, by offering solemnly her Son, and sacrificing to the divine justice his precious life. Hence St. Epiphanius called her a priest: “Virginem appello velut sacerdotem.”[1236] Now we begin to see how much this sacrifice cost her, and what heroic virtue she was obliged to practice when she had herself to sign the sentence of condemnation of her dear Jesus to death.
