The Seba library treats Theosis in 9 passages, across 4 authors (including Palmer, G. E. H. and Sherrard, Philip and Ware, Kallistos (trs.), Coniaris, Anthony M., Climacus, John).
Our theosis is in no sense merely symbolical or metaphorical: it is a genuine and specific reality, a pure gift of grace experienced even in this present life
Palamas establishes theosis as a concrete ontological reality—not symbolic transformation—that can be experienced bodily and spiritually in the present life as a direct gift of divine grace.

from dust to partakers of divine nature; from dust to theosis, becoming gods by grace as Jesus is God by nature
Coniaris articulates the classical patristic formula of theosis as the human vocation to become gods by participation in grace, in direct analogy to Christ's divine nature.
, Philokalia: The Bible of Orthodox Spirituality, 1998thesis
Man's life is a strenuous and endless ascent toward God, that is, deification (theosis)
Gregory of Nyssa, cited by Coniaris, defines theosis as the ceaseless upward movement of human life toward God, identifying deification with the fundamental dynamism of existence.
, Philokalia: The Bible of Orthodox Spirituality, 1998thesis
Theosis has everything to say to struggling humanity. It tells us that we have the capacity through the presence of God within us to transcend and overcome any and every difficulty in life
Coniaris presents theosis as the existentially operative dimension of Orthodox anthropology, offering not an abstract doctrine but a living assurance of divine indwelling that transforms suffering.
, Philokalia: The Bible of Orthodox Spirituality, 1998thesis
Many of those who are baptized have in them the seed of theosis but have never made an authentic act of personal faith... we do not enter into possession of the treasure (theosis) that actually belongs to us
Coniaris argues that theosis, though implanted sacramentally at baptism, requires the activated response of personal faith and ascetic cooperation to become a living reality.
, Philokalia: The Bible of Orthodox Spirituality, 1998thesis
One of the major means of theosis according to the Philokalia is expressed by the Greek word nepsis which means vigilance, watchfulness, alertness, attentiveness
Coniaris identifies nepsis—interior watchfulness—as a primary practical means toward theosis within the Philokalic tradition, linking contemplative discipline directly to divinization.

the experience of theosis on Mount Athos has often been described as a participation in the 'Taboric light'
The Philokalia translators establish the hesychast experience of the Taboric light as the phenomenological form in which theosis is encountered, linking divinization to the Transfiguration of Christ.
