Of course, Lewis remained an Anglican throughout his life; however, it is significant to note that for more than a century, and all through Lewis’ life, the Anglican and Orthodox churches were studying union. The Anglican Church began in the 16th century by adapting the liturgy of the Celtic (orthodox) church that was introduced when Britain was a Roman province, long before the schism between the Roman West and the Orthodox East. The Orthodox gave up the quest for union in the late 1960s when it became apparent that liberalism, not orthodox theology, would prevail in the Church of England.
It is very fair to describe Lewis as an "Anonymous Orthodox"—his official allegiance lay with the Church of England, but his sympathies lay with the Orthodox. The most thoughtful study of Lewis’ relationship to Orthodoxy was written by Bishop Kallistos Ware of Diokleia, who also teaches at Oxford. In an article published in Sobornost (an Anglican-Orthodox Ecumenical magazine) entitled "C.S. Lewis: an ‘Anonymous Orthodox’?" he explores this fascinating question. He humbly relates that Lewis has a tendency to "idealize us Orthodox," and affirms that "even though C.S. Lewis’ personal contacts with the Orthodox Church were not extensive at the same time his thinking is often profoundly in harmony with the Orthodox standpoint."
Although he can’t be looked upon as an Orthodox writer, his consistent sympathy for Orthodoxy has to be considered. As one of his biographers recalls (in "C.S. Lewis and His Times," by George Sayer), after a holiday spent in Greece together with Lewis and his wife, Lewis told him that of all the liturgies he’d ever attended, he preferred the Greek Orthodox liturgy to anything that he had seen in the West, Protestant or Roman Catholic. Then he went on to say that of all the priests and monks that he had ever had the opportunity to meet, the Orthodox priests that he ran across in his sojourn in Greece were the holiest, most spiritual men he had ever met. C.S. Lewis referred to a certain look they had, a sense. Lewis himself, in one of his letters, speaks of having been at an Orthodox liturgy and he said he loved it. He said "some stood, some sat, some knelt and one old man crawled around the floor like a caterpillar." He "absolutely loved it." We only know for sure that C.S. Lewis loved the Orthodox Church, though he never joined it and remained in the Anglican Church.

Quotes on Deification ;
It is a serious thing to live in a society of possible gods and goddesses, to remember that the dullest and most uninteresting person you talk to may one day be a creature which, if you saw it now, you would be strongly tempted to worship. . .
—C. S. Lewis, The Weight of Glory
God said to this hairless monkey, "get on with it, become a god."
—C. S. Lewis, A Grief Observed
(God) said that we were "gods" and He is going to make good His words. If we let Him-for we can prevent Him if we choose—He will make the feeblest and filthiest of us into a god or goddess, dazzling, radiant, immortal creature, pulsating all through with such energy and joy and wisdom and love as we cannot now imagine, a bright stainless mirror which reflects back to God perfectly (though, of course, on a smaller scale) His own boundless power and delight and goodness. The process will be long and in parts very painful; but that is what we are in for.
—C. S. Lewis, Mere Christianity 174-5
Morality is indispensable: but the Divine Life, which gives itself to us and which calls us to be gods, intends for us something in which morality will be swallowed up. We are to be remade. . . . we shall find underneath it all a thing we have never yet imagined: a real man, an ageless god, a son of God, strong, radiant, wise, beautiful, and drenched in joy.
—C. S. Lewis, The Grand Miracle, p. 85.

- p. 89 in "Tolkien’s The Lord of the Rings."
"…the imagined beings have their insides on the outside; they are visible souls." - ibid. (?)
"The Value of myth is that it takes all the things you know and restores to them the rich significane which has been hidden by the veil of familiarity." - p. 90
"…we do not retreat from reality, we rediscover it. As long as the story lingers in our mind, the real things are more themselves… By dipping them in myth we see them more clearly." - ibid. (?)
