Acts 17:13-23

But when the Jews of Thessalonica learned that the word of God [concerning eternal salvation through faith in Christ] had also been preached by Paul at Berea, they came there too, agitating and disturbing the crowds. So at that time the brothers immediately sent Paul away to go as far as the sea; but Silas and Timothy remained there [at Berea]. Those who escorted Paul brought him to Athens; and [after] receiving instructions [from Paul] for Silas and Timothy to join him as soon as possible, they left. Now while Paul was waiting for them at Athens, his spirit was greatly angered when he saw that the city was full of idols. So he had discussions in the synagogue with the Jews and the God-fearing Gentiles, and in the market place day after day with any who happened to be there. And some of the Epicurean and Stoic philosophers began to engage in conversation with him. And some said, “What could this idle babbler [with his eclectic, scrap-heap learning] have in mind to say?” Others said, “He seems to be a proclaimer of strange deities”—because he was preaching the good news about Jesus and the resurrection. They took him and brought him to the Areopagus (Hill of Ares, the Greek god of war), saying, “May we know what this [strange] new teaching is which you are proclaiming? For you are bringing some startling and strange things to our ears; so we want to know what they mean.” (Now all the Athenians and the foreigners visiting there used to spend their [leisure] time in nothing other than telling or hearing something new.) So Paul, standing in the center of the Areopagus, said: “Men of Athens, I observe [with every turn I make throughout the city] that you are very religious and devout in all respects. Now as I was going along and carefully looking at your objects of worship, I came to an altar with this inscription: ‘TO AN UNKNOWN GOD.’ Therefore what you already worship as unknown, this I proclaim to you.
