As is recorded in Matthew 10:5, the Lord said to His Apostles "Go not into the way of the Gentiles, and into any city of the Samaritans enter ye not..." Later the resurrected Lord told the same Apostles "...Ye shall be witnesses unto me both in Jerusalem, and in all Judea, and in Samaria, and unto the uttermost part of the earth." (Acts 1:8) This is not an example of any variableness or a shadow of turning (See James 1:17) but is ever more evidence of His wisdom and foreknowledge in executing His designs.
Some who wish to attack the Church think they find hypocrisy or guile in the fact that the Church did not allow men of African descent to hold the Priesthood until 1978. There is nothing contrary to the pattern of God in this. For decades and decades before the 2nd Official Declaration righteous men and women of African heritage were baptized into the Church and fold of God with the full promise and testimony that they would be denied no blessings in the worlds to come. Then, when the time was fully come, and as had been predicted by prophets previously, the Lord inspired His prophet to extend the full blessings of the Church in this life to all worthy members. This could well be one of the happiest days of this era.
Whether in this dispensation or any other anyone who is uncharitable to another due to their race is in direct defiance of the Gospel of Christ, who is Savior to "black and white, bond and free, male and female" (See the Book of Mormon, 2nd Nephi 26:33.)
