John Chrysostom : In order that those (workmen) also might become more reasonable, he says: "Wherefore if Demetrius, and the craftsman which are with him, have a matter against any man, the law is open, and there are deputies: let them implead one another. But if ye enquire anything concerning other matters, it shall be determined in a lawful assembly. For we are in danger to be called in question for this day's uproar, there being no cause, for which (matter) we shall not be able to give an account for this concourse." "A lawful assembly," he says, for there were three assemblies according to law in each month; but this one was contrary to law. Then he terrified them also by saying, "We are in danger to be called to account" for sedition. — Homily on Acts 42 Oecumenius : "and have recourse to the courts and to the magistrates." There was a class of judges in Asia called the magistrates, of humble status, who in some cases judged the poor and market-people; therefore they were called magistrates, just as there are public prosecutors in certain cities. The proconsuls, however, listened to cases concerning the rich or crimes. The term magistrates is also applied to advocates, from the word ἀγορεύειν, that is, "to speak publicly."
