Very interesting -- not sure I ever noticed that (or did I forget?).
I find it quite telling anyway that such a major symbolical sectarian feature as sacramental exclusivism (not acknowledging another church's baptism) was not directly introduced by Rutherford (as I would have thought) but was worked out by the structure itself long after his death, through the needs of inner consistency as it were.
It shows what kind of "changes" a structure can perform in the absence of creative and practical minds (counting FW Franz as a creative but not practical mind).
