This noun designates a proclaimer or herald, someone who announces or declares something publicly. In Acts 17:18, Epicurean and Stoic philosophers encounter Paul in Athens and ask, 'What does this babbler wish to say?' Others said, 'He seems to be a proclaimer (katangeleus) of foreign divinities'—because he preached Jesus and the resurrection. The term is neutral—a herald or announcer—but the philosophers use it dismissively. They recognize that Paul is proclaiming something, but they misunderstand his message as polytheistic, introducing new gods.
