"friendship, secrets which have been entrusted to him, and then turn the knowledge thus gained to his injury? Is it Christian charity to gather up every floating report, to unearth everything that will cast suspicion on the character of another, and then take delight in using it to injure him? Satan exults when he can defame or wound a follower of Christ. He is “the accuser of our brethren.” Shall Christians aid him in his work? 5T 95.2"
"And I heard a loud voice saying in heaven, Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ: for the accuser of our brethren is cast down, which accused them before our God day and night."
The phrase "the accuser of our brethren" is a direct quote and the context of defamation aligns perfectly.
"God's all-seeing eye notes the defects of all and the ruling passion of each, yet He bears with our mistakes and pities our weakness. He bids His people cherish the same spirit of tenderness and forbearance. True Christians will not exult in exposing the faults and deficiencies of others. They will turn away from vileness and deformity, to fix the mind upon that which is attractive and lovely. To the Christian every act of faultfinding, every word of censure or condemnation, is painful. 5T 95.3"
"And above all things have fervent charity among yourselves: for charity shall cover the multitude of sins."
Both passages emphasize the importance of love, forbearance, and covering sins rather than exposing faults. While not a direct quote, the thematic overlap is significant.
