But the matter is not so. It cannot be said that they did not hear. How could they fail to hear, when the whole inhabited world heard their proclamation?
Saint Chrysostom says on this passage: "The Apostle asks: what if the preachers were sent and preached what had been commanded them, but the Jews did not hear it?
"Then he gives the most sufficient answer to the objection: 'On the contrary, their sound has gone out into all the earth,' and so forth.
"What are you saying, Paul asks. They did not hear? The inhabited world heard. All the ends of the earth heard. How, then, could you not hear, among whom the preachers spent so much time and from whom they came?
"Is it possible? If the ends of the inhabited world heard, then all the more did you."
Let us continue this discourse with the words of Blessed Theodoret: "Was it possible for the Jews not to hear, when the Gentiles heard throughout the whole inhabited world?
"The preachers of truth proclaimed the preaching first to the Jews. For the Lord Himself said to them: 'Go rather to the lost sheep of the house of Israel' (cf. Matt. 10:6).
"And in the Acts of the Apostles it is said: 'It was necessary that the word of God should be spoken first to you' (cf. Acts 13:46)."
The prophetic word is taken from the Psalm (see Ps. 18:5). In that psalm, the holy prophet David first depicts how the heavens proclaim the glory of God.
They proclaim the wisdom, goodness, almightiness, creative power, and providence of the boundless God. Such preaching is heard everywhere and is understandable to all. All people hear it, and all, receiving this preaching of the heavens, repeat it in their own language.
Then he adds that the merciful God did not limit Himself to this proclamation of His glory. Together with this silent preaching from the face of creatures, He also granted us verbal revelation.
He gave the Law, the statutes, the commandments, and the judgments. These are "more to be desired than gold and much precious stone, sweeter also than honey and the honeycomb" (Ps. 18:11).
Thus, through revelation in creation, the Prophet was led to the thought of a better revelation through the word. There is nothing marvelous, then, if through both he prophetically discerned the future and higher revelation.
This revelation would come in the promised Deliverer who was to come. What is marvelous if, in the sun rising in the east "like a bridegroom from his chamber" (see Ps. 18:5-6), he discerned the Sun of righteousness?
This is Christ our God, who through the apostolic preaching was to traverse the whole inhabited world, beginning from the east, in order to warm all by His heat and enlighten them by His light.
And what is marvelous if, when he heard the glory of God proclaimed by creation being repeated in all languages, he also heard the preaching which the Apostles were to carry in all languages throughout the whole world?
What the prophetic spirit discerned in hidden fashion, the apostolic spirit saw and understood. Now it openly proclaims to all as prophecy: "Their sound has gone out into all the earth."
