Reaching this fi nal point of this comparative study between Jung’s and Maximus’ developmental models, namely between individuation and deifi cation, an overlapping while diverging discourse emerges. The overlaps and diversions may give rise to a partial complementarity: ‘partial’ because there are elements entirely different in each theory due to the dissimilar ontological and epistemological underpinnings. These overlaps, however, permit considering a compound view of both psychological and spiritual development within the suggested framework of the fi ve ontological levels. The reservoir of the external and the internal factors that are essential for development should be sought within this framework. In fact, the Jungian and Maximian systems address numerous potentialities spanning the psychosomatic, the socio-cultural, and the metaphysical levels. In this respect, the two models, as seen together, could establish an intriguing dialogue among psychology, philosophy, and theology, a dialogue that also engages certain ideas and methodologies from modern sociology and physics (as previously discussed in various points of this book). It is thus a broader trans-disciplinary framework within which the Jungian and Maximian models unfold and reveal their ‘strong’ and ‘weak’ points while simultaneously complementing each other.
