Acts 17:19-20

The exact location of the Areopagus (Gr., Areios Pagos; lit. court or council of Ares, the Greek god of war) is difficult to determine. The Athenians used the word in two ways in Luke’s day. It referred to the Hill of Ares (i.e., Mars Hill) on which the Council of the Areopagus conducted its business in ancient times. It also referred to the group of about 30 citizens known as the Council of the Areopagus who met in the Royal Portico of the Agora. [Note: Barclay, pp. 141-42.] The question is, does "the Areopagus" refer to the people or the place? Luke’s description is ambiguous, though I favor the people in view of the context.

The Council of the Areopagus had authority over religion, morals, and education in Athens. Its members wanted to know what Paul was advocating. Enemies of Socrates had poisoned him for teaching strange ideas in Athens, so Paul was in some danger.
