It’s a First World 🌎 problem.
All kidding aside, the Watchtower publications have always had this rather stuffy, stilted, overly-formal style of writing that—to my ear at least—sounds about a generation behind the average age of their congregants. (And no, I don’t mean an overlapping generation).
It’s been my suspicion that they think it makes them sound smart and educated; however, if they really were educated they would know it doesn’t.
TIP: If you’re really interested in upping your game in the writing department, pick up a copy of Steven Pinker’s book, The Sense of Style. You’ll be glad you did.
