“But the Virgin, by conceiving the Word within her body, ‘deified the human race and made earth a heaven.’ The Word ‘became the Son of Man, sharing in mortality, to turn human beings into sons of God and make them partakers of divine immortality.’ How believers appropriate this within the ecclesial community is illustrated typologically. The incarnate Word gave us baptism as a sacrament and type of his burial and resurrection to deify both the soul and body. His transfiguration opened the eyes of his disciples, showing them that human nature has been deified by union with the Word of God.
We must imitate him in his earthly life to become partakers of his resurrection and fellow-heirs with Christ. Through fasting and night vigils we are ‘renewed and deified’ in our inner being. This transformation of our human nature, first in the representative humanity of Christ and then in our own person through the life of faith, is thoroughly traditional and patristic.” (Norman Russel in St. Vladimir’s Theological Quarterly: Vol. 50, #4, p 377-378)
