I have only vaguely followed this matter. I’m not familiar with the proceedings and how things may or may not have been done in an appropriate manner, or may or may not have followed the rules set forth by the LDS church itself (again, I don’t know since I haven’t really followed it in depth).
However, I do think it is important to remember that as Catholics, we affirm the true teaching, even dogma, that only men are able to be ordained to the priesthood. Various Popes throughout Catholic history have affirmed this. While Mormonism’s situation on the matter is more nuanced, especially since it has women performing ordinances for other women in the temple, and has a history of women performing healing/anointing blessings, among other things, Ms. Kelly, from what I have seen so far, does seem to be affirming and teaching things contrary to current Mormon teaching and practice, as well as what Catholics would see as the historical and true Christian practice on priesthood ordination. Having looked at the Ordain Women’s website, it seems as if this organization actively and explicitly advocates for the ordination of women to the priesthood. They say that it is “necessary”, and strongly criticize the practice of having a male-only priesthood.
Perhaps I’m rambling, but my point is that, while perhaps the situation is a little more complicated if we judge Mormonism on its own (and that perhaps there is a cause for LDS women to be ordained to the priesthood based on Mormonism’s own teachings, history, practices, etc), and maybe the LDS church did wrong things in approaching this (again, I don’t know, I haven’t looked into it too much), we must not forget that as Catholics, we know that the dogma of the true Church is that women cannot be validly ordained to the priesthood (as our own “ordain women”-esque Women Priests groups have attempted to do), and that to me, it does seem as if her support (founding?) of a group openly teaching ideas contrary to the current LDS church practices (clearly making the belief in a male priesthood out to be false, antiquated, etc), inviting others to join in support of it, and presenting “discussions” to disseminate to others to “faithfully agitate” for change in the LDS church would be cause for some sort of discipline (as opposed to merely discussing the historical and theological matter). This also reminds me of the temple recommend question, “
Do you support, affiliate with, or agree with any group or individual whose teachings or practices are contrary to or oppose those accepted by the Church of Jesus Christ of Latter-day Saints?” To me, this is a pretty clear example of that.
My two cents.
