I previously posted about Don Garlington’s commentary on Galatians being available as a free PDF from the Paul Page. But I wasn’t sure exactly which Galatians commentary it was. So I emailed Dr. Garlington and got the official answer.
As for Galatians, I appreciate that the situation is confusing. The thing has gone through an “evolutionary process.” First there was the manuscript for EBC, which was submitted three years ago and still awaits publication (supposedly in the Fall). That is a very basic commentary aimed at a more general audience.
