Extraordinary claims require extra ordinary proof.
Absolutely. And the claims being made by Serge definitely qualify. Essentially he's claiming to have exclusive access to knowledge that completely trumps the bulk of human understanding of medical, scientific and religious issues. Moreover, little to no evidence is provided to support these claims.
It's not enough for Serge to say "suck eggs, Darwinians" (which he has done) while discussing his theory of the origins of human life (our spirits willed themselves into physical form on Earth) when absolutely no evidence can be offered to support that theory.
It's not enough to claim to be able to transcend dimensions (which he does) when he's clearly still standing in the room while making the claim that he's in the 5th dimension.
Child-like shapes printed on paper (supposedly images of the souls of UM students) are not proof that Serge can see what his students souls look like. Yet he makes this claim.
On top of the absence of proof supporting the bulk of UM's theology, there is a lack of internal logic with some of the claims.
For example, according to karmic law as presented by Serge, if a person is sexually assaulted or suffers from some other reprehensible act inflicted by another person, this is because the victim committed a similar offence in a previous life, thus the crime (while clearly unpleasant) is simply a 'correction' - an occurence for the victim to learn from that sets their karmic balance straight.
At the same time, according to UM teachings 'entities' are evil spirits that have seperated from God's love and exist to malevolently influence mankind and keep humanity from re-connecting to our divine source (God). UM theology maintains that murders, suicides and sexual assault are the result of human beings being manipulated by these astral entities.
So apparently, the evil entities that have seperated from God and exist to keep humanity seperate from God, are causing (abhorrent) behaviours that deliver karmic balance to humans, and instill the necessary lessons that people need to learn from in order for our souls to evolve back to God.
Logic suggests then that these astral entities are actually playing a crucial part in the Hierarchy's 'divine plan' and thus nothing to worry about, despite UM's teaching's to the contrary.
