JWoods, weren't you an elder at one time....teaching means teaching about the Bible to the congregation. The fact remains that Barbara Anderson researched and drew up articles for the Awake, ones that were not teaching bible information. I don't think holy spirit has to be behind an article about a hummingbird. Perhaps she wore a headcovering.
The question remains whether any articles in WTS publications had any help by the holy spirit........
It is felt by some scholars that Deborah wrote the victory song in Judges chapter 5.
