From
https://en.wikipedia.org/wiki/Church_of_Bible_Understanding :
In November 2013, the AP investigated claims that the church was at fault for running sub-standard housing for orphans in Haiti after the two homes the church runs received a failing grade from the Haitian agency that monitors orphanages. "...Even though they claim in IRS filings to be spending around $2.5 million annually, the home for boys and girls was so dirty and overcrowded during recent inspections that the government said it shouldn't remain open."
CoBU is a cult in the older sense of the word, if not the newer connotation as well. They are followers of a particular leader who claims, personally, to be the sole authority on understanding the Bible. Not unlike Charles Taze Russell, except that Russell did not require followers to cut off ties to family and friends as CoBU apparently does. Maybe more similar to the Children of God cult and Mo Berg.
