The opening resembles the titles of St. Paul's letters, and perhaps James is the author of it, whoever he may be. He was unacquainted with Paul's custom of writing to one particular nation and city, and for a particular reason. Instead, this author writes to the twelve tribes scattered among the nations because of the captivity, and not to the churches in every place, because he had no particular reason to be so specific.
