After reading this whole thread I feel like we need to come back to the original question for the sake of those looking for the truth about this ministry:
I am an ex member of this group. My wife and I were part of it to various extents for more than 10 years. Before we left in 2023 we were more involved with the inner workings and we were heavily involved, but we were not local in TN. Since then we've discovered much as we've disentangled from this group. We still have friends on the inside that we love and pray for and hope that they will be set free too. Perhaps in the future I can share our full story if it might help anyone. At least, this UBM group is very tiny and David's reach is very small - hardly anyone knows about them or follows them - but the ones that do and have are still suffering from the damage of the spiritual abuse. Novertheless, the friends and family of those still in this mess needs to know the truth and be set free, by the grace of God
With regards to UBM, if you would like to know whether it is an authoritative high controlling group, whether your friends and family are indeed in a religious cult - then please go through my notes on comparing Steven Hassan's BITE model of criteria for over-reach with the methods of David Eells and Michael Hare's Unleavened Bread Ministries (UBM). I have attached in PDF with my comments in red - this would be a good reference and starting point and clear indication for what we are actually dealing with here.
Note: In order to keep the notes short I have not linked to the evidence. All notes are either our own personal experience or evidenced by others. If anyone would like specific evidence and can't find support for it on their own self-condemning ubm1.org website (which admittedly is very hard to navigate) please send me a message. There are lots of evidence for these comments on YouTube on the @TruthsBehindCults channel too. I am not associated with the channel but I am grateful for whoever it is that is making this available publicly and lifting the lid on the inner workings of UBM and the spiritual abuse that goes with it.
@FSSL - if you have a loved one in there then I will pray for them that God opens their eyes and sets them free. He has done it for so many.
God bless you all - let's be kind to and have grace for each other like our Lord Jesus would
