Acts 18:15 - Ellicott's Commentary On The Whole Bible

But if it be a question of words and names, and of your law. — The second noun is in the singular number in the Greek. St. Paul was known as a speaker, one who preached the word of God, and with that, as distinct from acts, Gallio had nothing to do. The “names” were those which he had probably heard of at Rome, even before he came to Corinth. (See Note on Acts 18:2.) Was a teacher whom both parties spoke of as Jesus the Nazarene entitled also to bear the name of Christos? In the emphasis laid on “your law” (literally, the law which affects you), the judge intimates that he sees through their appeal to law. It is Jewish, and not Roman law, which they are seeking to vindicate, and he will not make himself, as Pilate, after a weak protest (John 18:3), had done (Gallio may well have known the history), the executioner of an alien code. With a strong emphasis on the pronoun, he ends with, “I, for my part, have no wish to be a judge of these things.”
