x 35 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?  36 Seeing then that these things cannot be denied, you ought to be quiet and do nothing rash. 37 For you have brought these men here who are neither sacrilegious nor blasphemers of our goddess. 38 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. 39 But if you seek anything further,  it shall be settled in the regular assembly. 40 For we really are in danger of being charged with rioting today, since there is no cause that we can give to justify this commotion.” 41 And when he had said these things, he dismissed the assembly. (Acts 19:35-41 (ESV)
The town clerk sends everyone home. Rioting was a dangerous thing for a city in Paul’s day. It was considered treason, or rebellion against Rome. And for it Roman armies would be sent to destroy a city. This was something the no one wanted.
At least the town clerk did not find the men guilty of sacrilege or blasphemy. This wasn’t something Paul would engage in. He would preach his faith, and he might challenge a person one on one in a discussion to think deeper about their own faith. But he didn’t trash the faith of others, no matter how ridiculous he thought their faith was.
Recently I heard Dr. Kleinig saying that “no one is ever converted by rubbishing their religion.” Therefore there is no need to. Even if at times we have found ourselves doing it. It usually just gets their defenses up. Tends to shut down conversation. There are just better ways.
