I continued: "So up until June 8, 1978, only a white, Melchizedek Priesthood bearing male could be come a son of perdition. Now thanks be to the Lord, since 1978, you too can become a son of perdition." I thought he was turning pale white in front of me. He stammered a little and said: "I had never looked at it that way before!" I assured him that most people hadn't. Then I turned to the Sister Stake Missionary who had brought the Black investigator, and said to her: "Up until this very day, God is still discriminating against 50% of His children in not allowing them to hold the priesthood-- they are women. But (I continued), I vote that women can also hold the priesthood and they too can become sons of perdition!" By this time their entire demeanor had changed.
it certainly reads as though he was teaching 'God was protecting blacks before 1978 by not letting them hold the priesthood.'
