A Christian Regeneration centre operates only on Biblical principles. It does not recognize human philosophy or secular psychological principles in terms of human behaviour. Neither does it use psychiatric drugs to treat mental diseases that do not exist. It does not employ diagnostic principles such as contained in the Diagnostic Statistical Manual of Mental Disorders. In a Regeneration centre emphasis is placed on disobedience to God as the main cause for our darkened emotions and subsequent dysfunctional behaviour. The only authoritative reference manual is the Christian Bible. It contains everything that humans need to correct their thinking, feelings, beliefs and behaviour. Because it is sufficient in every way it may not be integrated with other belief systems.
