I found these reposts of Gen-Ups at Xfamily really helpful for understanding the the keys doctrine, which goes hand-in-hand with TFI's current preoccupation with demons & spirit helpers.
I have two immediate thoughts about this material. First, it seems to encourage quite a lot of magical thinking in older children. If you're familiar with Piaget's theory of cognitive development, magical thinking is typical of toddlers up to about age six, when kids are in the pre-operational phase. At the age where Gen-Ups are targeted, kids should be working on concrete operational tasks, which require logical and systematic manipulation of symbols related to concrete objects.
In other words, a kid is taught to claim the power of the keys and call on Boheme to fight the demon Bacchus, who temps him with a desire for worldly addictions. A 9-year-old logically expects the desire for worldly addictions (e.g., internet games) to be removed by the power of the keys. When the desire to play internet games (instead of go out witnessing) is NOT removed, the kid faces a huge contradiction: Adults tell him this stuff works, and he can't make it work. It must be his fault...
As one SG commented on this stuff not too long ago, "What the f*...?"
My other thought about the key-to-the-spirit-helper doctrine is that people with a history of trauma are prone to dissociative disorders, a mental state that lends itself to a belief in psychicism. I would imagine there's a fairly high number of SGA parents in TFI who space out on a regular basis and go into dissociative states where they "see" and "hear" all sorts of things. Or perhaps even "channel" beings they imagine as coming from outside themselves, when in fact these are disowned parts of their own mind & personality. These are typically people lacking in a strong sense of personal empowerment, so that calling on supernatural forces offers a way to have a greater sense of control over their lives. I would think that a fair number of SGAs who remained in TFI don't have any problem at all teaching their offspring about power keys and spirit helpers.
What will be interesting is what happens when the youngest generation reaches adolescence, the abstract operational phase of cognitive development. Hopefully they'll grow up with a lot less trauma. Nevertheless, they are just as likely as many of the SGAs who left TFI in the 90s and 00s to perceive their parents as religious nuts.
