29 “Instead of your fathers, children are born to you”. Nothing can be more manifest. Now consider the “Temple of the King” itself, for it is on its behalf he speaks, on account of the unity of the body that is spread throughout all the world: for those very persons who have chosen to be virgins, cannot find favour with the King unless they be led into the Temple of the King. “Instead of your fathers, are your children born to you.” It was the Apostles begot you: they were “sent:” they were the preachers: they are “the fathers.” But was it possible for them to be with us in the body for ever? Although one of them said, “I desire to depart, and to be with Christ, which is far better: to abide in the flesh is necessary for your sakes.” It is true he said this, but how long was it possible for him to remain here? Could it be till this present time, could it be to all futurity? Is the Church then left desolate by their departure? God forbid. “Instead of your fathers, children have been born to you.” What is that? The Apostles were sent to you as “fathers,” instead of the Apostles sons have been born to you: there have been appointed Bishops. For in the present day, whence do the Bishops, throughout all the world, derive their origin? The Church itself calls them fathers; the Church itself brought them forth, and placed them on the thrones of “the fathers.” Think not yourself abandoned then, because you see not Peter, nor see Paul: see not those through whom thou were born. Out of your own offspring has a body of “fathers” been raised up to you. “Instead of your fathers, have children been born to you.” Observe how widely diffused is the “Temple of the King,” that “the virgins that are not led to the Temple of the King,” may know that they have nothing to do with that marriage. “You shall make them princes over all the earth.” This is the Universal Church: her children have been made “princes over all the earth:” her children have been appointed instead of the “fathers.” Let those who are cut off own the truth of this, let them come to the One Body: let them be led into the Temple of the King. God has established His Temple everywhere: has laid everywhere “the foundations of the Prophets and Apostles.” The Church has brought “forth sons;” has made them “instead of her fathers” to be “princes over all the earth.”
30. “They shall be mindful of your name in every generation and generation; therefore shall the peoples confess unto You”. What does it profit then to “confess” indeed and yet to confess out of “the Temple”? What does it profit to pray, and yet not to pray on the Mount? “I cried,” says he, “unto the Lord with my voice: and He heard me out of His holy hill.” Out of what “hill”? Out of that of which it is said, “A city set upon a hill cannot be hid.” Of what “hill”? Out of that hill which Daniel saw “grow out of a small stone, and break all the kingdoms of the earth; and cover all the face of the earth.” There let him pray, who hopes to receive: there let him ask, who would have his prayer heard: there let him confess, who wishes to be pardoned. “Therefore shall the peoples confess unto you for ever, world without end.” For in that eternal life it is true indeed there will no longer be the mourning over sins: but yet in the praises of God by that everlasting City which is above, there will not be wanting a perpetual confession of the greatness of that happiness. For to that City itself, to which another Psalm sings, “Glorious things are spoken of you, O City of God,” to her who is the very Bride of Christ, the very Queen, a “King's daughter, and a King's consort;”...the peoples shall for this very cause confess even to herself; the hearts of all, now enlightened by perfect charity, being laid bare, and made manifest, that she may know the whole of herself most completely, who here is, in many parts of her, unknown to herself....
