 In this tradition, theoria means understanding that the Uncreated cannot be grasped by the logical or rational mind, but only by the whole person (unity of heart and mind); this perception is that of the nous.God was knowable in his manifestations, but ultimately, one must transcend knowledge or gnosis, since knowledge is based on reflection, and because gnosis is limited and can become a barrier between man and God (as an idolatry).If one wishes to commune with God, one must enter into the Divine filial relation with God the Father through Jesus Christ, one in ousia with the Father, which results in pure faith without any preconceived notions of God.
