From a commentary on Isaiah by Eusebius of Caesarea

The voice in the wilderness

The voice of one crying in the wilderness: Prepare the way of the Lord, make straight the paths of our God. The prophecy makes clear that it is to be fulfilled, not in Jerusalem but in the wilderness: it is there that the glory of the Lord is to appear, and God’s salvation is to be made known to all mankind.

It was in the wilderness that God’s saving presence was proclaimed by John the Baptist, and there that God’s salvation was seen. The words of this prophecy were fulfilled when Christ and his glory were made manifest to all: after his baptism the heavens opened, and the Holy Spirit in the form of a dove rested on him, and the Father’s voice was heard, bearing witness to the Son: This is my beloved Son, listen to him.

The prophecy meant that God was to come to a deserted place, inaccessible from the beginning. None of the pagans had any knowledge of God, since his holy servants and prophets were kept from approaching them. The voice commands that a way be prepared for the Word of God: the rough and trackless ground is to be made level, so that our God may find a highway when he comes. Prepare the way of the Lord: the way is the preaching of the Gospel, the new message of consolation, ready to bring to all mankind the knowledge of God’s saving power.

Climb on a high mountain, bearer of good news to Zion. Lift up your voice in strength, bearer of good news to Jerusalem. These words harmonize very well with the meaning of what has gone before. They refer opportunely to the evangelists and proclaim the coming of God to men, after speaking of the voice crying in the wilderness. Mention of the evangelists suitably follows the prophecy on John the Baptist.

What does Zion mean if not the city previously called Jerusalem? This is the mountain referred to in that passage from Scripture: Here is mount Zion, where you dwelt.The Apostle says: You have come to mount Zion.Does not this refer to the company of the apostles, chosen from the former people of the circumcision?

This is the Zion, the Jerusalem, that received God’s salvation. It stands aloft on the mountain of God, that is, it is raised high on the only-begotten Word of God. It is commanded to climb the high mountain and announce the word of salvation. Who is the bearer of the good news but the company of the evangelists? What does it mean to bear the good news but to preach to all nations, but first of all to the cities of Judah, the coming of Christ on earth?

“I shall be satisfied when your glory is seen” by St. Thomas Aquinas

From a conference by Saint Thomas Alquinas –
I shall be satisfied when your glory is seen

It is fitting that the end of all our desires, namely eternal life coincides with the words at the end of the creed, “Life everlasting. Amen.”

The first point about eternal life is that man is united with God. For God himself is the reward and end of all our labors: I am your protector and your supreme reward. This union consists in seeing perfectly: At present we see through a glass, darkly; but then we shall see face to face.

Next it consists in perfect praise, according to the words of the prophet: Joy and happiness will be found in it, thanksgiving and words of praise.

It also consists in the complete satisfaction of desire, for there the blessed will be given more than they wanted or hoped for. The reason is that in this life no one can fulfill his longing, nor can any creature satisfy man’s desire. Only God satisfies, he infinitely exceeds all other pleasures. That is why man can rest in nothing but God. As Augustine says: You have made us for yourself, Lord, and our heart can find no rest until it rests in you.

Since in their heavenly home the saints will possess God completely, obviously their longing will be satisfied, and their glory will be even greater. That is why the Lord says: Enter into the joy of your Lord. Augustine adds: The fullness of joy will not enter into those who rejoice, but those who rejoice will enter into joy. I shall be satisfied when your glory is seen, and again: He who satisfies your desire with good things.

Whatever is delightful is there in superabundance. If delights are sought, there is supreme and most perfect delight. It is said of God, the supreme good: Boundless delights are in your right hand.

Again, eternal life consists of the joyous community of all the blessed, a community of supreme delight, since everyone will share all that is good with all the blessed. Everyone will love everyone else as himself, and therefore will rejoice in another’s good as in his own. So it follows that the happiness and joy of each grows in proportion to the joy of all.
