"I was shown that the brothers B and their families are descending lower and lower. “Clouds they are without water, carried about of winds; trees whose fruit withereth, without fruit;” and if they continue in the course they have been pursuing, they will finally be “twice dead, plucked up by the roots.” In leaning to their own understanding, they have gone down to the point where they have no practical godliness, no heaven, no God as theirs. 4T 335.1"
"These are spots in your feasts of charity, when they feast with you, feeding themselves without fear: clouds they are without water, carried about of winds; trees whose fruit withereth, without fruit, twice dead, plucked up by the roots;"
EGW directly quotes Jude 1:12, applying its imagery to the brothers B and their families. The phrase "Clouds they are without water, carried about of winds; trees whose fruit withereth, without fruit, twice dead, plucked up by the roots" is a clear and intentional reference.
