"The Blind Leading the Blind I have seen how the blind guides were laboring to make souls as blind as themselves, little realizing what is coming upon them. They are exalting themselves against the truth, and as it triumphs, many who have looked on these teachers as men of God and have looked to them for light, are troubled. They inquire of these leaders relative to the Sabbath, and they, with the object of getting rid of the fourth commandment, will answer them thereto. I saw that real honesty was not regarded in taking the many positions that were taken against the Sabbath. The main object is to get around the Sabbath of the Lord and observe another day than that sanctified and hallowed by Jehovah. If they are driven from one position, they take an opposite one, even a position that they had but just before condemned as unsound. EW 68"
"Let them alone: they be blind leaders of the blind. And if the blind lead the blind, both shall fall into the ditch."
EGW directly uses the phrase 'blind leading the blind' and applies it to religious leaders, mirroring the meaning and context of Matthew 15:14.
"Woe unto them that call evil good, and good evil; that put darkness for light, and light for darkness; that put bitter for sweet, and sweet for bitter!"
Both passages address the issue of leaders distorting truth and misleading others. While not a direct quote, the concept of calling good evil and evil good aligns with the idea of 'blind guides' leading people astray.
"God's people are coming into the unity of the faith. Those who observe the Sabbath of the Bible are united in their views of Bible truth. But those who oppose the Sabbath among the Advent people are disunited and strangely divided. One comes forward in opposition to the Sabbath and declares it to be thus and so, and at the conclusion calls it settled. But as his effort does not put the question to rest, and as the Sabbath cause progresses and the children of the Lord still embrace it, another comes forward to overthrow it. But in presenting his views to get around the Sabbath, he entirely tears down the arguments of him who made the first effort against the truth, and presents a theory as opposite to his as to ours. So with the third and the fourth; but none of them will have it as it stands in the Word of God: “The seventh day is the Sabbath of the Lord thy God.” EW 68.2"
"Till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ:"
Both passages discuss the concept of unity within the faith. While the EGW passage focuses on unity regarding the Sabbath, it still aligns with the broader theme of Ephesians 4:13, which speaks of coming into the unity of the faith.
