What I have read about her is much more focused on her very extensive (and generally unrecognized) work in the civil rights movement, with much less emphasis on her gender identity.

Also, it is misleading to say that the Episcopal Church "proclaimed her a saint."  The Episcopal Church does not make saints in the way the Catholic Church does. It has a book, "Holy Women, Holy Men," containing brief biographies of people considered worthy of special admiration, including many of the traditional saints, and not necessarily limited to Episcopalians.
