The " all partakers are the slave , equal parts of the body of Christ " always sounded contrived. The change from "all the remnant" to "brothers in Brooklyn" was only affirming reality. Where wt went too far is demoting all pre -1919 Christian writers from the ranks of the F&DS too, -- Apostles, Paul, Luke, James and all.
That is why there is no more "Bible" in the WTB&TS, organ, jworg. not only are many of the present partaker flaky, bible writers/characters were too.
