Way to Perfection, pg. 102; “In the spirit of sympathy, mercy and faith, we will also hope that blessings may eventually be given to our negro brethren, for they are our brethren-children of God-notwithstanding their black covering emblematical of eternal darkness.” – Apostle Joseph Fielding Smith
James 2:1-4; “My brethren, have not the faith of our Lord Jesus Christ, the Lord of glory, with respect of persons. 2 For if there come unto your assembly a man with a gold ring, in goodly apparel, and there come in also a poor man in vile raiment; 3 And ye have respect to him that weareth the gay clothing, and say unto him, Sit thou here in a good place; and say to the poor, Stand thou there, or sit here under my footstool: 4 Are ye not then partial in yourselves, and are become judges of evil thoughts?”
The LDS book used above was written in 1949 by then apostle Joseph Fielding Smith who later became the tenth president/prophet of the Church.
