In the past, the authorship of the lessons in the SS Quarterly were identified by naming the “author.” At that time, some of the authors did not recognize the printed lessons as what they had written. I guess that many of them complained rather strongly to the staff of the Sabbath School Department of the General Conference which edited the manuscripts for publication. Again, just guessing, I imagine that as a results of these complains the staff decided to identify the authors of the lessons as “principal contributors.” The Spanish version of the Quarterlies, however, still uses the descriptor “autor.”
A few days ago, talking with Felix Cortez I asked him whether he had recognized the printed version of the manuscript he had sent to the SS Department. He answered saying that they had not made many changes to the manuscript. One of them, however, was that he had written consistently “the author of Hebrews.” The editors had changed that to “Paul.”
Before talking with Felix I had noticed that at first the printed Quarterly does read “the author of Hebrews,” and I was surprised and glad to see that. Soon, however, I noticed that the author was identified as “Paul.” Apparently the staff at the SS Department did not catch on to the issue at first.
