And when the town clerk had quieted the crowd, he said, “Men of Ephesus, who is there who does not know that the city of the Ephesians is temple keeper of the great Artemis, and of the sacred stone that fell from the sky? Seeing then that these things cannot be denied, you ought to be quiet and do nothing rash. For you have brought these men here who are neither sacrilegious nor blasphemers of our goddess. If therefore Demetrius and the craftsmen with him have a complaint against anyone, the courts are open, and there are proconsuls. Let them bring charges against one another
I ask this with nothing in particular in mind, nor anyone. Even Paul’s famous speech on Mars Hill was respectful towards those with whom Paul disagreed. What makes this respectful stance of Paul very interesting (to me at least), is that he was the central villainous character earlier in Acts. He persecuted (quite violently) followers of  “The Way” (the initial name for Christians). However, after his conversion experience on the road to Damascus, his entire methodology changed.
It would seem that there are some lessons there.
