I remember back in the 80's that we were asked to offer some older publications that we had on hand. One of them was "Life Everlasting in Freeom of the Sons of God." I still remember a sister giving a demonstration on how she would offer it. That was the publication that first mentioned the 1975 date. Even though still a loyal dub, I couldn't bring myself to offer that book. I chose another one that was more benign.
