"Science says that life began when in some unexplained way, a correct combination of chemical reactions produced a molecule capable of making copies of itself by triggering further chemical reactions. Such a description of the enormous and teeming complexity and power of the LIFE FORCE as being discernible because it is 'capable of replicating itself', reveals the basic impoverishment of scientific perception and thought which produced such a theory! Furthermore, the suggestion that such a combination of 'inanimate' chemicals could get together in a specific way - accidentally - to produce such an astounding result of 'self-replication' remains unquestioned scientifically. This is because the finite human mind, even though scientific, cannot deal with such a strange eventuality of uninitiated 'self-replication'. It is too suggestive of a magical occurrence - of some intervention from an unimaginable source which scientific men dare not contemplate for fear of ridicule. This sheep-like acquiescence is considered more scientific than producing 'inspired' theories blocked by the materialistic laws science has established for itself. This block to future scientific progress will prevent science properly investigating the realm of mind and spirit until some enlightened scientist defies convention and dares to cross the borderline between the 'seen and the 'unseen'.
Prophets of old, if presented with the theory of molecular self-replication would have no difficulty with such a 'magical occurrence' and would say that 'God' made the chemical combinations and imbued them with life. That would not be the right explanation either. It is this old religious concept of a 'God on High' 'creating from afar' which is blocking the man of science from moving forward to more spiritually aware reflections. Therefore, despite science's seeming emancipation from age-old doctrines, it is still as mentally bound and hindered by fears of ancient shibboleths as in the 19th century. It adopts its ridiculous theories because it has not yet perceived the 'Reality' of Our Source of Being behind and with in the living molecule." [Christ Returns - Speaks His Truth, Letter 5, page 8-9]
"Fifthly, I have come expressly to help science bridge the gulf between UNIVERSAL CONSCIOUSNESS and the appearance of electrical particles. Without this bridge between the Unseen Spiritual Dimension and the Seen world of 'matter', science will remain rooted in old ideas and concepts instead of moving forward into new realms of spiritual/scientific research for the betterment of mankind."
