Enneagram: (from the Greek ennéa = nine + gramma = sign) the name refers to a diagram composed of a circle with nine points on its circumference, connected within the circle by a triangle and a hexangle. It was originally used for divination, but has become known as the symbol for a system of personality typology consisting of nine standard character types. It became popular after the publication of Helen Palmer's book The Enneagram,(97) but she recognises her indebtedness to the Russian esoteric thinker and practitioner G.I. Gurdjieff, the Chilean psychologist Claudio Naranjo and author Oscar Ichazo, founder of Arica. The origin of the enneagram remains shrouded in mystery, but some maintain that it comes from Sufi mysticism.
The Enneagram redefines sin, among other fundamental concepts, by simply associating faults with personality types, which is particularly tempting in a cultural climate of irresponsibility and narcissism. It encourages an unhealthy self-absorption about one’s own “type,” so that the type is at fault rather than the person. This gives rise to a deterministic mindset at odds with Christian freedom
And an old book but good....
