D&C Official Declaration 2

In June, 1978 -

"...the First Presidency announced that a revelation had been received by President Spencer W. Kimball extending priesthood and temple blessings to all worthy male members of the Church..." Doctrine and Covenants Official Declaration 2:2)

In a letter, the First Presidency declared -

"Aware of the promises made by the prophets and presidents of the Church who have preceded us that at some time, in God's eternal plan, all of our brethren who are worthy may receive the priesthood, and witnessing the faithfulness of those from whom the priesthood has been withheld, we have pleaded long and earnestly in behalf of these, our faithful brethren, spending many hours in the Upper Room of the Temple supplicating the Lord for divine guidance.
8 He has heard our prayers, and by revelation has confirmed that the long-promised day has come when every faithful, worthy man in the Church may receive the holy priesthood, with power to exercise its divine authority, and enjoy with his loved ones every blessing that flows therefrom, including the blessings of the temple." (Doctrine and Covenants Official Declaration 2:7 - 8)

There were many that thought then and now that this response by the Church was because of increasing political and social pressure. But the account of Elder Bruce R. McConkie provides greater incite and truth on the matter as stated by the First Presidency -

"On the first day of June in this year, 1978, the First Presidency and the Twelve, after full discussion of the proposition and all the premises and principles that are involved, importuned the Lord for a revelation. President Kimball was mouth, and he prayed with great faith and great fervor; this was one of those occasions when an inspired prayer was offered. You know the Doctrine and Covenants statement, that if we pray by the power of the Spirit we will receive answers to our prayers and it will be given us what we shall ask (D&C 50:30). It was given President Kimball what he should ask. He prayed by the power of the Spirit, and there was perfect unity, total and complete harmony, between the Presidency and the Twelve on the issue involved.

And when President Kimball finished his prayer, the Lord gave a revelation by the power of the Holy Ghost. . . .

On this occasion, because of the importuning and the faith, and because the hour and the time had arrived, the Lord in his providences poured out the Holy Ghost upon the First Presidency and the Twelve in a miraculous and marvelous manner, beyond anything that any then present had ever experienced. The revelation came to the President of the Church; it also came to each individual present. There were ten members of the Council of the Twelve and three of the First Presidency there assembled. The result was that President Kimball knew, and each one of us knew, independent of any other person, by direct and personal revelation to us, that the time had now come to extend the gospel and all its blessings and all its obligations, including the priesthood and the blessings of the house of the Lord, to those of every nation, culture, and race, including the black race. There was no question whatsoever as to what happened or as to the word and message that came.

The revelation came to the President of the Church and, in harmony with Church government, was announced by him; the announcement was made eight days later over the signature of the First Presidency. But in this instance, in addition to the revelation coming to the man who would announce it to the Church and to the world, and who was sustained as the mouthpiece of God on earth, the revelation came to every member of the body that I have named. They all knew it in the temple.

In my judgment this was done by the Lord in this way because it was a revelation of such tremendous significance and import; one which would reverse the whole direction of the Church, procedurally and administratively; one which would affect the living and the dead; one which would affect the total relationship that we have with the world; one, I say, of such significance that the Lord wanted independent witnesses who could bear record that the thing had happened." (“All Are Alike unto God,” (Symposium on the Book of Mormon, p. 2.)

That is the testimony of a modern apostle we sustain as a prophet, seer, and revelator. I believe it happened just as Elder McConkie so stated. Not according to the opinions of the world.
