"So long as we see the Word of God take flesh in the letter of Holy Writ in a variety of figures we have not yet spiritually seen the incorporeal and simple and singular and only Son. As the Scripture says, 'The one who has seen me has seen the Father,' and also, 'I am in the Father and the Father is in me.' It is, therefore, very necessary for a deep knowledge that we first study the veils of the statements regarding the Word and so behold with the naked mind the pure Word as he exists in himself, who clearly shows the Father in himself, as far as it is possible for men to grasp. Thus it is necessary that the one who seeks after God in a religious way never hold fast to the letter lest he mistakenly understand things said about God for God himself. In this case we unwisely are satisfied with the words of Scripture in place of the Word, and the Word slips out of the mind while we thought by holding on to this garment we could possess the incorporeal Word."
-- Maximus the Confessor, 5th century
