Paul felt it necessary to issue his corrective because in early Christian congregations, following Jewish practice, it was permissible and customary to interrupt the preacher to ask questions. In first-century synagogues, a sermon followed the reading of Scripture. This exposition of Scripture was more a lesson than a sermon, and congregants were encouraged to ask questions. In fact, the asking of questions was so central to the rabbinic teaching method that often the preacher-teacher began his sermon by just seating himself and waiting until someone from the audience asked a question. There is a whole category of Jewish literature called xxx xxxxx (
ye lam DE nu ra BE nu, May our teacher instruct us). It is similar to what we now call “Questions and Answers.” Today public speakers often employ a Question-and-Answer period, especially as a means of clarification at the end of a lecture. In first-century Jewish society this approach was usually the main method of instruction.
From Paul’s injunction we learn that at public religious gatherings of early Christians, women sat with men in the same hall, perhaps even next to their husbands or fathers. Paul’s command itself implies a mixed audience: there would have been nothing indecorous about a woman asking a question in a group composed entirely of women.
