The problem I have with this poll is that, at least for me, the options miss the point. A vision can be both "physical" and "spiritual." That is, a literal visitation in the flesh is at the same time an awake, spiritual vision. Although I never got round to posting it (apologies to MFB and Jeremy Orbe-Smith with whom I was going to share), I spent two or three days in the library a few months back, gathering sources for a blog post on just this topic. A vision is not something which doesn't literally or physically exist. That is to misunderstand the mystic, visionary experience. The hidden nature of things is something that can't be percieved by the senses in an ordinary way, but must be opened by the power of God. It is then that the recipient is able to see things as they truly are. From Enoch, to Elisha, to the blind Christian widows in Rome, to St. Maximus the confessor, to Joseph Smith to the Zlotchover Rebbe, to St. Serafim Sarovsky, to St. Silouan, the visionary experience means seeing into the hidden, beyond what the noraml use of our faculties can reveal.
If one considers Motovilov's recollections of St. Serafim, it becomes obvious that the experience involved the physical, IE., palpable, tangible, physical.
More than once in other passages of Holy Scripture the appearance of God to men is mentioned.
"That is why some people say: 'These passages are incomprehensible. Is it really possible for people to see God so openly?' But there is nothing incomprehensible here. This failure to understand has come about because we have departed from the simplicity of the original Christian knowledge. Under the pretext of education, we have reached such a darkness of ignorance that what the ancients understood so clearly seems to us almost inconceivable. Even in ordinary conversation, the idea of God's appearance among men did not seem strange to them. Thus, when his friends rebuked him for blaspheming God, Job answered them: How can that be when I feel the Spirit of God in my nostrils? (cp. Job 27:3). That is, 'How can I blaspheme God when the Holy Spirit abides with me? If I had blasphemed God, the Holy Spirit would have withdrawn from me; but lo, I feel His breath in my nostrils.'
"In exactly the same way it is said of Abraham and Jacob that they saw the Lord and conversed with Him, and that Jacob even wrestled with Him. Moses and all the people with him saw God when he was granted to receive from God the tables of the law on Mount Sinai. A pillar of cloud and a pillar of fire, or, in other words, the evident grace of the Holy Spirit, served as guides to the people of God in the desert. People saw God and the grace of His Holy Spirit, not in sleep or in dreams, or in the excitement of a disordered imagination, but truly and openly...
What else do you feel, your Godliness?"
I answered: "An extraordinary warmth."
"How can you feel warmth, my son? Look, we are sitting in the forest. It is winter out-of-doors, and snow is underfoot. There is more than an inch of snow on us, and the snowflakes are still falling. What warmth can there be?"
I answered: "Such as there is in a bath-house when the water is poured on the stone and the steam rises in clouds."
"And the smell?" he asked me. "Is it the same as in the bath-house?"
"No," I replied. "There is nothing on earth like this fragrance. When in my dear mother's lifetime I was fond of dancing and used to go to balls and parties, my mother would sprinkle me with scent which she bought at the best shops in Kazan. But those scents did not exhale such fragrance."
And Father Seraphim, smiling pleasantly, said: "I know it myself just as well as you do, my son, but I am asking you on purpose to see whether you feel it in the same way. It is absolutely true, your Godliness! The sweetest earthly fragrance cannot be compared with the fragrance which we now feel, for we are now enveloped in the fragrance of the Holy Spirit of God. What on earth can be like it? Mark, your Godliness, you have told me that around us it is warm as in a bath-house; but look, neither on you nor on me does the snow melt, nor does it underfoot; therefore, this warmth is not in the air but in us. It is that very warmth about which the Holy Spirit in the words of prayer makes us cry to the Lord: 'Warm me with the warmth of Thy Holy Spirit!' By it the hermits of both sexes were kept warm and did not fear the winter frost, being clad, as in fur coats, in the grace-given clothing woven by the Holy Spirit. And so it must be in actual fact, for the grace of God must dwell within us, in our heart, because the Lord said: The Kingdom of God is within you
(Lk. 17:21). By the Kingdom of God the Lord meant the grace of the Holy Spirit. This Kingdom of God is now within us, and the grace of the Holy Spirit shines upon us and warms us from without as well. It fills the surrounding air with many fragrant odours, sweetens our senses with heavenly delight and floods our hearts with unutterable joy. Our present state is that of which the Apostle says; The Kingdom of God is not food and drink, but righteousness and peace and joy in the Holy Spirit
(Rom. 14:17). Our faith consists not in the plausible words of earthly wisdom, but in the demonstration of the Spirit and power (cp. I Cor.2:4). That is just the state that we are in now. Of this state the Lord said: There are some of those standing here who shall not taste of death till they see the Kingdom of God come in power
(Mk. 9:1). See, my son, what unspeakable joy the Lord God has now granted us! This is what it means to be in the fullness of the Holy Spirit, about which St. Macarius of Egypt writes: 'I myself was in the fullness of the Holy Spirit.' With this fullness of His Holy Spirit the Lord has now filled us poor creatures to overflowing. So there is no need now, your Godliness, to ask how people come to be in the grace of the Holy Spirit. Will you remember this manifestation of God's ineffable mercy which has visited us?"
