Isaiah

Isaiah was a Hebrew prophet who lived in the 8th century BCE. He was born in Jerusalem to a family of unknown social status. He was well-educated and familiar with the traditional forms and language of prophetic speech. Isaiah was married and had two sons.

Isaiah's prophetic career began in 742 BCE, when he was called by God to preach to the people of Israel. He warned the people that they were in danger of being punished by God for their sins. Isaiah also spoke about the future of Israel, and he predicted the coming of a Messiah.

Isaiah's writings are found in the Book of Isaiah, which is the longest book in the Hebrew Bible. Isaiah's prophecies are often concerned with the relationship between God and the people of Israel. His writings have been interpreted in many different ways over the centuries. Isaiah is considered one of the most important prophets in the Hebrew Bible because his writings have had a profound impact on both Jewish and Christian traditions.

For example, Isaiah's prophecy about the coming of a Messiah is one of the most famous passages in the Bible. In Isaiah 7:14, Isaiah predicts the birth of a child who will be called "Immanuel," which means "God with us." This prophecy is often interpreted as a reference to Jesus Christ.

Isaiah's writings have also been influential in the development of Jewish thought. For example, Isaiah's concept of the Suffering Servant is one of the most important concepts in Jewish theology. The Suffering Servant is a figure who is chosen by God to suffer for the sins of the people. This concept has been interpreted in many different ways, but it is often seen as a foreshadowing of the Messiah.

Isaiah's writings have had a profound impact on both Jewish and Christian traditions. His prophecies are still studied and debated today, and his writings continue to inspire people around the world.

Theme: Belief and Faith

Isaiah 7.9 [Short Commentary]

The prophet Isaiah’s quote “Unless you have believed, you will not understand” is a powerful statement about the importance of faith. It suggests that belief is not just a matter of intellectual assent, but also a way of being in the world. When we believe, we open ourselves up to new possibilities and new ways of understanding the world around us.

Isaiah 7.9 [Longer Commentary]

This quote has been significant for both the Jewish and Christian faiths. In the Jewish tradition, it is often interpreted as a warning against the dangers of doubt. The rabbis taught that if we do not believe in God, we will not be able to understand the divine plan for the world.

In the Christian tradition, this quote has been interpreted in a number of ways. Saint Augustine, for example, interpreted it as a statement about the relationship between faith and reason. He argued that faith is the starting point for understanding, and that reason can only take us so far. Saint Thomas Aquinas also emphasized the importance of faith, but he argued that faith and reason can work together to lead us to a deeper understanding of God.

Pope Francis has also reflected on this quote in his encyclical Lumen Fidei. He writes that “Unless you have believed, you will not understand” means that “faith is not an intellectual assent to a set of propositions, but a personal adherence to the living God who reveals himself to us.” He goes on to say that “faith is not opposed to reason, but demands reason’s full engagement.”

In conclusion, the quote “Unless you have believed, you will not understand” is a powerful reminder of the importance of faith. It suggests that belief is not just a matter of intellectual assent, but also a way of being in the world. When we believe, we open ourselves up to new possibilities and new ways of understanding the world around us.

Pope Francis on Isaiah 7.9

Pope Francis’s (2013) reflection on this quote helps us to see that faith is not opposed to reason, but demands reason’s full engagement. When we use our reason to explore the world around us, we are led to a deeper understanding of God.

Unless you believe, you will not understand (cf. Is 7:9). The Greek version of the Hebrew Bible, the Septuagint translation produced in Alexandria, gives the above rendering of the words spoken by the prophet Isaiah to King Ahaz. In this way, the issue of the knowledge of truth became central to faith. The Hebrew text, though, reads differently; the prophet says to the king: “If you will not believe, you shall not be established”. Here there is a play on words, based on two forms of the verb: “you will believe” and “you shall be established”. Terrified by the might of his enemies, the king seeks the security that an alliance with the great Assyrian empire can offer. The prophet tells him instead to trust completely in the solid and steadfast rock which is the God of Israel. Because God is trustworthy, it is reasonable to have faith in him, to stand fast on his word. He is the same God that Isaiah will later call, twice in one verse, the God who is Amen, “the God of truth” (cf. Is 65:16), the enduring foundation of covenant fidelity.

―Pope Francis [Lumen Fidei, June 29, 2013].

Isaiah 65:1

“I am ready to be approached by those who do not study me, ready to be found by those who do not seek me. I say, “I am here, I am here” to people who do not even invoke my name.”
