"Some of the Sabbathkeepers who say to the world that they are looking for Jesus’ coming, and that they believe we are having the last message of mercy, give way to their natural feelings, and barter, and trade, and are a proverb among unbelievers for their keenness in trade, for being sharp, and always getting the best end of a bargain. Such would better lose a little and exert a better influence in the world, and a happier influence among brethren, and show that this world is not their god. 1T 150.2"
"No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. Ye cannot serve God and mammon."
Both passages address the conflict between serving God and worldly pursuits. EGW's statement about Sabbathkeepers being overly concerned with trade echoes the sentiment of Matthew 6:24.
"For the name of God is blasphemed among the Gentiles through you, as it is written."
Both passages address the idea that the behavior of believers reflects on their faith and can either honor or dishonor God. EGW speaks of Sabbathkeepers whose sharp business practices bring the faith into disrepute, while Romans 2:24 states that the name of God is blasphemed among Gentiles because of the behavior of Jews.
"I saw that brethren should feel interested for one another. Especially should those who are blessed with health have a kind regard and care for those who have not good health. They should favor them. They should remember the lesson taught by Jesus of the good Samaritan. 1T 150.3"
"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 parable of the good Samaritan, making this a clear allusion.
"Bear ye one another’s burdens, and so fulfil the law of Christ."
Both passages encourage believers to care for one another, though EGW focuses on physical health while Galatians speaks more broadly about burdens. The connection is strong enough to confirm.
"Said Jesus: “Love one another, as I have loved you.” How much? His love cannot be told. He left the glory that He had with the Father before the world was. “He was wounded for our transgressions, He was bruised for our iniquities: the chastisement of our peace was upon Him; and with His stripes we are healed.” He patiently bore every indignity and scorn. Behold His agony in the garden, when He prayed that the cup might pass from Him! Behold His sufferings on Calvary! All this for guilty, lost man. And Jesus says: “Love one another, as I have loved you.” How much? Well enough to give your life for a brother. But has it come to this, that self must be gratified, and the word of God neglected? The world is their god. They serve it, they love it, and the love of God has departed. If ye love the world, the love of the Father is not in you. 1T 150.4"
"This is my commandment, That ye love one another, as I have loved you."
The EGW passage directly quotes John 15:12, making it an explicit allusion.
"But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed."
The EGW passage directly quotes Isaiah 53:5, making it an explicit allusion.
"And now, O Father, glorify thou me with thine own self with the glory which I had with thee before the world was."
The EGW passage alludes to John 17:5, referencing Jesus' glory with the Father before the world was. While not a direct quote, the reference is clear and intentional.
