The Watchtower says that Witnesses may -
- Go to meetings, assemblies, conventions
- Watch JW broadcast
- Read Watchtower publications
The Watchtower says that Witnesses may not -
- Discuss spiritual things at independent social gatherings
- Pray before such gatherings
As a child growing up as a born-in Witness I remember that Saturday morning were field service and after lunch was the family study of preparing for the following day's Watchtower study at the meeting. Dad was start the study by offering a prayer. Dad conducted the Watchtower study. We took turns reading the paragraphs and cited scriptures.
So, in short, the Watchtower no condemns what I grew up with.
I also remember as a child going camping with multiple families from the congregation. The whole camping party would have a Watchtower study together because we were out camping instead of being at the meeting. I am sure such an activity would also be condemned.
