On deification – 9

The deifying gift of the Spirit is “the deifying energy of the superessential divine essence, although not the totality of this energy … Deification is … everywhere, ineffably present in the essence and inseparable from it, as its natural power. But if [the divine manifestation] seizes a suitable material, free from every veil … then it becomes itself visible like a spiritual light, or rather it transforms these creatures into spiritual light” (Gregory Palamas, III. 1.34)
