Isaiah 66:13

A mother draws her children near her; we seek our mother, the church. Whatever is weak and young has an appeal and sweetness and lovableness of its own, just because in its weakness it does stand in need of assistance. But God does not withhold assistance from such an age of life. Just as the male and female parent regard their young tenderly—whether it be horses their colts, or cows their calves, or lions their cubs, or deer their fawn or men and women their children—so, too, does the Father of all draw near to those who seek his aid, giving them a new birth and making them his own adopted children. He recognizes them as his little ones, he loves only them, and he comes to the aid of such as these and defends them. That is why he calls them his children.

(Verse 13, 14) Just as a mother caresses her child, so will I comfort you, and in Jerusalem you will find comfort. Your heart will rejoice and your bones will flourish like grass. The hand of the Lord will be known to his servants, and he will be angry with his enemies. The Septuagint translates 'servants' as 'those who fear' and 'enemies' as 'unbelievers'; the rest is the same. We learn from the example of mothers, who surpass all charity by nourishing their children with love in their arms, the mercy of the Creator towards his creatures. Finally, wanting to show how much He loves and cares for those whom He has created, God asks, 'Can a woman forget her nursing child, that she should have no compassion on the son of her womb? Even these may forget, yet I will not forget you' (Isaiah 49:15). This sentiment is also expressed in the Gospel when the Lord speaks to Jerusalem, saying, 'How often would I have gathered your children together as a hen gathers her brood under her wings, and you would not' (Matthew 23:37). And in Deuteronomy, it is written: As an eagle protects its nest and desires its young, spreading its wings, it receives them and carries them on its shoulders (Deut. XXXII, 11). Those who have written about the nature of animals say that all beasts, and even beasts of burden, and cattle, and birds have an innate affection for their offspring, but the greatest love is that of eagles, which build their nests in high and inaccessible places to protect their young from the serpent. They also say that among its feathers is found a stone called amethyst, which surpasses all poisons. If this is true, the affection of God towards his creatures is rightly compared to that of the eagles, who protect their offspring with constant vigilance, so that the ancient dragon and serpent, the devil and Satan, may not approach the newly hatched chicks, and so that all the snares of their adversaries may be broken by the name of the stone that is laid in the foundations of Zion. This Jerusalem, in which the sons will find consolation in their mother's embrace and will kneel, is the same Jerusalem of which the Apostle writes: 'But the Jerusalem that is above is free, which is our mother' (Galatians 4:26). Satisfied with the milk of this consolation, he comforted others who needed his words, saying: Blessed be God, the Father of mercies, and the God of all consolation,…
