Isaac was meant to be the type of Jesus Christ sacrificed for the human race; he was intended to be a figure of the propagation of the faithful; he should be great in the order of grace. Still, he was born out of the order of nature, of parents also barren by reason of their age. He who was to prepare the way for the impending appearance of the Redeemer, and who was to be more than a prophet and the greatest amongst the saints, he also was miraculously born of parents aged and barren; not to speak of other distinguished personages, both of the Old and New Testaments, who in various ways were born in a supernatural manner to exalt the stupendous works of omnipotence and of grace. Not otherwise did the Lord, who in His lofty designs intended great things for our heroine, dispose that her conception should be most remarkable and above the order of nature. Amata became conscious of the wonderful event, and, full of amazement, she dared not credit the evidence of it. In such a state she felt her heart agitated, now by fears that she was deceived, again by hope of the contrary; at one time by shame at so unusual an occurrence at such an age as hers, at another her feelings of wonder overwhelmed her; and again she experienced renewed struggles of fresh fears, emotions, and passions. But, as is the way with the just, the troubled woman had recourse to prayer to the Father of light, to the God of consolation, and whilst she persevered in her humble, fervent, and constant prayers, there appeared to her an angel, a bearer of certainty, of peace, and of happy tidings, as an angel appeared to Abraham and Sara while they were employed in the charitable exercise of hospitality, and to Zachary amidst his prayers and offerings of incense. However joyful and consoling in itself was this angelic apparition, it did not fail to cause in her heart feelings of perturbation. Daniel and the other prophets had a like sensation in similar circumstances; Zachary had the same feelings, and so had the most holy Mother of God herself. The reason is, as Blessed Simon of Cascia wisely observes, that humanity is naturally disturbed and stricken with fear at the sudden sight of things extraordinary or greater than itself. But, as the same blessed writer adds, since those heavenly spirits, when they are sent for our relief, are accustomed to comfort the timid, thus, as the archangel told the father of the future Precursor not to fear, and by the announcement of his birth in the near future calmed his heart with efficacious words, so did another ambassador from heaven bring the same security and joy to the troubled mind of Rita's mother, and assure her that she should bring forth a child; and that nothing should be wanting to the fulness of her consolation, he made known to her in brief the eminent virtues and glory of the daughter that was to be born to her, as the sanctity of the Baptist was likewise foretold to Zachary.
