Isaías 33
Bede
Isaías 33:6
But "true wealth" signifies either the joy of eternal life itself, concerning which it is written, "the riches of his inheritance in the saints," or those spiritual virtues with which the fullness of life is attained, about which Isaiah said, "the riches of salvation, wisdom, and knowledge; the fear of the Lord himself is its treasure.""And if you are unfaithful with goods that are not yours, who will give you something of your own?" The resources of this world are alien to us, that is, external to the nature of our habitat, "for we brought nothing into this world and we are without doubt unable to take anything from it." Our possession is the kingdom of heaven, our life is Christ, and our wealth consists in the fruitfulness of spiritual works, about which Solomon said, "The redemption of a man's soul is his wealth." — On the Gospel of Luke 5:16.11-12
Isaías 33:7
But if you want to see that the ancient prophets were terribly sad and aggrieved about the future blinding of their nation, which was the cause of our illumination, listen to Isaiah, for when he was sent to announce beforehand the grace of the Lord's coming, saying that "a light has arisen upon those who dwell in the region of the shadow of death," he responded immediately to the advent of the same light, saying "you have enlarged the nation; you have not increased its joy." And elsewhere, while commemorating the despondency of this people, Isaiah said, among other things, "the messengers of peace will weep bitterly, referring to the prophetic heralds of the divine word." — Commentary on Samuel 3:16.1
Isaías 33:17
Through the sacraments of his humanity with which we have been imbued, we may be able to attain the contemplation of the glory of his divinity, that contemplation which he himself in his faithful benevolence pledged to his faithful servants when he said, "One who has my commandments and keeps them, he it is who loves me. One who loves me will be loved by my Father, and I will love him and manifest myself to him." He says, "I will manifest myself"—that is, "Not in such a way that everyone can look at me, or in such a way that even the unfaithful can see me and crucify me, but in such a way that only the pure eyes of the saints can see 'the King of ages in his beauty.' " In this way I will show myself to those who love me, so as to reward them for their love. Therefore let us hope, as we have said, that through the visible nature of his humanity we may be able to ascend to see the beauty of his divinity, if we keep these sacraments as we have received them, unblemished in the worthy honor of justice and holiness and truth, if we follow his example in his human way of life, and if we humbly follow the words of the teaching which he ministered to us through his humanity. — Homilies on the Gospels 1:19
Isaías 33:17
The disciples indeed saw him coming in his kingdom, for on the mountain they saw him shining in that brightness with which he will be seen in his kingdom by all the saints when the judgment has been brought to completion. But since the eyes of the disciples were still mortal and corruptible, they were then unable to sustain what the whole church of the saints will have the power to look upon when she has become incorruptible through resurrection. Concerning this it is written, "Their eye will see the king in his beauty." — Homilies on the Gospels 1:24
