I recall as though it was only 60 years ago, sitting in the Kingdom Hall on those horrible chairs, learning of the FOUR forms of love: Agape, Philia, Storge and Eros.
The Watchtower never mentioned Pragma.
Pragma: This is a committed, compassionate love that often grows as two partners continue to cherish and care for each other. This type of love is associated with being together for a long time. In some cases, the passion of eros can grow into pragma over time, this forging a lasting bond.
I think I know why; the Watchtower isn't into committed, compassionate, cherishing and caring, are they?
OH! I WAS 60 years ago!
