This is an exchange between Jane Little and Michael Otterson in Little’s BBC piece “Sister Saints – Women and the Mormons” (starting at about 11:20; also see the accompanying article here):
JL: Just to deal with Kate Kelly, just to clarify, was she excommunicated for apostasy?
MO: The letter that went out, that they actually published on their website, briefly, at least they released it to the media, indicated that the reason why that disciplinary action was taken was for apostasy. I’m not sure it actually used the word, but apostasy is seen as repeated and deliberate advocating to doctrines contrary to the Church, especially encouraging other people to take the same position.
JL: So you would say she is an apostate, under that definition?
MO: Yeah.
JL: The dictionary definition says it’s renouncing your faith, which is somewhat different.
MO: Well, I don’t think I[‘m] particularly obligated to worry about what it says in Oxford or Merriam-Webster’s Dictionary. Our definition of apostasy is repeated open advocacy of doctrines contrary to the Church.
It’s not surprising that Otterson would want to use an unconventional definition of apostasy. It allows him to use a more serious-sounding word than “insufficient submissiveness in the face of leaders’ demands” in explaining why Kate Kelly had to be kicked out. I realize, of course, that he was taking his definition from the Handbook, but that just means it’s the Church leaders who wrote or commissioned the Handbook who are making up a new definition to allow them to borrow strength from an existing weighty word.
