"The men of talent among the colored believers are to be laborers together with God for their own people. And yet there will sometimes be opportunities for them to bear a testimony in tent meetings and in large assemblies, which will reach many, many souls. These opportunities will appear as the Southern field is worked and the loud cry is given. When the Holy Spirit is poured out, there will be a triumph of humanity over prejudice in seeking the salvation of the souls of human beings. God will control minds. Human hearts will love as Christ loved. And the color line will be regarded by many very differently from the way in which it is now regarded. To love as Christ loves, lifts the mind into a pure, heavenly, unselfish atmosphere. 9T 209.1"
"For we are labourers together with God: ye are God’s husbandry, ye are God’s building."
EGW directly uses the phrase 'laborers together with God' from 1 Corinthians 3:9, applying it to the specific context of colored believers working for their own people. This is more than a thematic parallel; it's a direct application of a biblical principle.
He who is closely connected with Christ is lifted above the prejudice of color or caste. His faith takes hold of eternal realities. The divine Author of truth is to be uplifted. Our hearts are to be filled with the faith that works by love and purifies the soul. The work of the good Samaritan is the example that we are to follow. 9T 209.2 We are not to agitate the color line question, and thus arouse prejudice and bring about a crisis. The light of the third angel's message is to be given to those who need light. We are to labor calmly, quietly, faithfully, trusting in our Elder Brother. We are not to be in haste to define the exact course to be pursued in the future regarding the relation to be maintained between white and colored people. The truth for this time is to be proclaimed before the thousands of people in the Southern States. The way is to be cleared, as far as possible, of all obstruction. Let the gospel message be given to the people. Let white and colored people be labore…
"But he, willing to justify himself, said unto Jesus, And who is my neighbour? And Jesus answering said, A certain man went down from Jerusalem to Jericho, and fell among thieves, which stripped him of his raiment, and wounded him, and departed, leaving him half dead. And by chance there came down a certain priest that way: and when he saw him, he passed by on the other side. And likewise a Levite, when he was at the place, came and looked on him, and passed by on the other side. But a certain Samaritan, as he journeyed, came where he was: and when he saw him, he had compassion on him, And went to him, and bound up his wounds, pouring in oil and wine, and set him on his own beast, and brought him to an inn, and took care of him. And on the morrow when he departed, he took out two pence, and gave them to the host, and said unto him, Take care of him; and whatsoever thou spendest more, when I come again, I will repay thee. Which now of these three, thinkest thou, was neighbour unto him that fell among the thieves? And he said, He that shewed mercy on him. Then said Jesus unto him, Go, and do thou likewise."
EGW explicitly mentions 'The work of the good Samaritan is the example that we are to follow.' This is a direct reference to the parable in Luke 10:29-37, making it an explicit allusion.
"There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus."
EGW's statement about being 'lifted above the prejudice of color or caste' because of connection with Christ strongly echoes the sentiment of Galatians 3:28, which declares equality in Christ regardless of social distinctions. While not a direct quote, the thematic resonance is clear and powerful.
