One excerpt that deals with this issue:
Elsewhere they explain how the nine types are also derived from the "nine passions" outlined by the Desert Fathers.Pacwa disagrees that there are "nine faces of God" of which each Enneagram type is a distortion. He claims "God does not have nine faces. . . . [T]here are three coequal persons in the one God [and] these three persons are neither multiplying nor subdividing into nine faces." Pacwa apparently does not know that the source of this image of the "nine faces of God" is the mystical Hebrew teaching called the Kabbalah. The Christian perspective of which we are aware both respects its Jewish roots and respects the Jewish faith as a sister faith to Christianity. Also, the word "faces" is a metaphor for "attributes." These terms are used interchangeably in the Kabbalah. Thus, the Enneagram relies on ancient Kabbalistic tradition for saying there are nine faces of God. We will deal with Pacwa’s problem with distorting the face of God in the next point.
