"Let care and wisdom be shown in dealing with workers who, though they have made mistakes, have manifested an earnest, self-sacrificing interest in the work. Let their brethren say: “We will not make matters worse by putting another in your place, without giving you opportunity to retrieve your mistake, and to stand on vantage ground, free from the burden of unjust criticism.” Let them be given time to adjust themselves, to overcome the difficulties surrounding them, and to stand before angels and men as worthy workers. They have made mistakes, but would those who have questioned and criticized have done better? To the accusing Pharisees Christ said: “He that is without sin among you, let him first cast a stone.” John 8:7 . 7T 278.3"
"So when they continued asking him, he lifted up himself, and said unto them, He that is without sin among you, let him first cast a stone at her."
Ellen White directly references John 8:7 in this passage.
