"OW has been asking for revelation on women for over a year now and never, at no point in time has the Prophet Thomas S. Monson even remotely mentioned bringing this before the Lord personally, nor has he claimed to have been given any additional insight concerning women from the Lord. At best we have gotten Elder Oaks quoting Joseph Fielding Smith and J. Reuben Clark as his official references for why women are “appendages” of the priesthood but will never hold it. Never mind the fact that both Joseph Fielding Smith and J. Reuben Clark erroneously supported and taught of the divine nature and providence behind the ban on black people holding the Priesthood for 150 years (which the church now entirely disavows). Did I mention that J. Reuben Clark was famous for ensuring that the Utah blood banks were free of “negro blood” so that those upstanding, white, male priesthood holders’ authority wouldn't be voided by a blood transfusion with mixed-race bloods? (3) These are the men that Oaks quoted in his most recent talk on the Priesthood."[...]3) D. Michael Quinn’s biography, “Elder Statesman: A Biography of J. Reuben Clark” (Salt Lake City, Utah: Signature Books, 2002) “Clark’s attitudes toward Blacks was equally reprehensible. Along with others of his time, he opposed intermarriage and supported the common practice of segregating blood supplies in hospitals to ensure that no white person would be infused with blood from a Black person, and thus either invalidate his priesthood or disqualify him from future priesthood. But as time progressed, so did his attitude toward Blacks. As the Church extended its missionary efforts into South America and determining blood lines became more difficult, he came to something of an accommodation in the case of some Brazilians, even ‘wondering whether we could not work out a plan, while not conferring the priesthood as such upon them, we could give them opportunity to participate in the work certainly of the Aaronic Priesthood grades.
