In the confluct among UBF leaders and their critics, UBFers often feel confirmed that the leaders are on the right side ("God's people") and critics are bad people (belong to "Satan") by these references in the Bible (I took those from NT, while hardcore UBFers also will take passages from the OT, comparing Samuel Lee with Mose etc.):
Bad people "sneak in" and "secretly slip in" (Gal 2:4 and Jude 4).
Bad people "despise authority" (2Peter 2:10 and Jude 8).
Bad people "went out" (2Tim 4:10 and 1John 2:19).
What can be said about this? (More in the comments)
