The temperature of Heaven can be rather accurately computed from available data. Our authority is the Bible: Isaiah 30:26 reads, Moreover the light of the Moon shall be as the light of the Sun and the light of the Sun shall be sevenfold, as the light of seven days. Thus Heaven receives from the Moon as much radiation as we do from the Sun and in addition seven times seven (forty-nine) times as much as the Earth does from the Sun, or fifty times in all. The light we receive from the Moon is a ten-thousandth of the light we receive from the sun, so we can ignore that. With these data we can compute the temperature of Heaven. The radiation falling on Heaven will heat it to the point where the heat lost by radiation is just equal to the heat lost by radiation. Using the Stefan-Boltzmann fourth power law for radiation and where H is the temperature of Heaven, E that of the Earth – 300 K – we have
(H/E)4 = 50.
This gives H as 798 K or 525°C.
The exact temperature of Hell cannot be computed but it must be less than 444.6°C, the temperature at which brimstone or sulphur changes from a liquid to a gas. Revelations 21:8: But the fearful, and unbelieving . . . shall have their part in the lake which burneth with fire and brimstone. A lake of molten brimstone means that its temperature must be below the boiling point, which is 444.6°C.
We have, then, temperature of Heaven, 525°C. Temperature of Hell, less than 445°C. Therefore, Heaven is hotter than Hell.

One brief remark before continuing: one man I knew was in an elevator on a sweltering hot day, when a profusely sweating jogger stepped into the elevator and said, “It’s hotter ‘n Hell out there!” and he replied, slowly, “No, it isn’t.” There is something amiss with the humorous quote above, and Mark Twain, the great humorist, wrote, “The secret source of humor itself is not joy but sorrow. There is no humor in Heaven.” There is a sense in Orthodoxy that humor does not belong in the holiest places, and devout Orthodox I know have a deep joy but laugh little. The connotations of “humorless” do not describe them; they are not sour, nor joyless, nor rigid, nor quick to take offense, but they are luminous with the Light of a Heaven that needs no humor.
But the physicist quoted above underscores something: words are inadequate to capture Heaven. There are situations in life where words fail us: people say, “Words cannot express how grateful I am.” And if words fail us for expressing gratitude, for instance, or romantic love, they fail all the more in describing Heaven and God. “Eye has not seen, ear has not heard, heart has not conceived, what God has prepared for them that love him:” words cannot express Heaven, nor God.
In classical theology this is spoken of as God’s transcendence: God is infinitely far beyond any created thing. He is reflected in a million ways in our created world, but the hidden transcendent God is beyond all of them. In a book of profound influence but only a few pages long, The Mystical Theology, St. Dionysius writes of ascending towards God:
The fact is that the more we take flight upward, the more our words are confined to the ideas we are capable of forming; so that now as we plunge into that darkness which is beyond intellect, we shall find ourselves not simply running short of words but actually speechless and unknowing…
So this is what we say. The Cause of all is above all and is not inexistent, lifeless, speechless, mindless. He is not a material body, and hence has neither shape nor form, quality, quantity, or weight. He is not in any place and can neither be seen nor be touched. He is neither perceived nor is he perceptible. He suffers neither disorder nor disturbance and is overwhelmed by no earthly passion. He is not powerless and subject to the disturbances caused by sense perception. He endures no deprivation of light. He passes through no change, decay, division, loss, no ebb and flow, nothing of which the senses may be aware. None of all this can either be identified with it nor attributed to it.
Again, as we climb higher we say this. He is not soul or mind, nor does he possess imagination, conviction, speech, or understanding. Nor is he speech per se, understanding per se. He cannot be spoken of and he cannot be grasped by understanding. He is not number or order, greatness or smallness, equality or inequality, similarity or dissimilarity. He is not immovable, moving, or at rest. He has no power, he is not power, nor is he light. He does not live nor is he life. He is not a substance, nor is he eternity or time. He cannot be grasped by the understanding since he is neither knowledge nor truth. He is not kingship. He is not wisdom. He is neither one nor oneness, divinity nor goodness. Nor is he a spirit, in the sense in which we understand that term. He is not sonship or fatherhood and he is nothing known to us or to any other being. He falls neither within the predicate of nonbehing nor of being. Existing beings do not know him as he actually is and he does not know them as they are. There is no speaking of him, nor name nor knowledge of him. Darkness and light, error and truth—he is none of these. He is beyond assertion and denial. We make assertions and denials of what is next to him, but never of him, for he is both beyond every assertion, being the perfect and unique cause of all things, and, by virtue of his preeminently simple and absolute nature, free of every limitation, beyond every limitation; he is also beyond every denial.
Over a millenium before a Bultmann would go on a program of saying that the images we have in Scripture are inadequate, the Orthodox Church would do one better. Her saints would tell of the hidden transcendent God who transcends everything we might say of him. And better than this can be said. God transcends his own transcendence, and transcends transcendence itself. And here we must leave Bultmann completely behind as not having gone far enough.
God transcends his own transcendence, and the transcendent God so far transcends his own transcendence that not only is he infinitesmally close to the Creation, immanent to all Creation, but he entered his Creation: God became man. And the reason God became man is that man might become divine. And there is never a sharp separation between Christ coming to save mankind and Christ coming to save the whole Creation: the transcendent God so far transcends his own incomparable transcendence that he is at work to deify men, and ultimately the whole Creation. In Christ there is no male nor female, paradise nor inhabitated world, heaven nor earth, spiritual nor material, uncreated nor created, but Christ is all, and in all, and transcends all, and in him all these differences are to be transcended. The transcendent Christ God transcends his Creation and transcends his own transcendence, and he returns to his Father in victory, bearing deified men and Creation as trophies who share in his transcendent victory. There is no distinction between male and female, paradise and the inhabited world, heaven and earth, spiritual and material, uncreated God and created creation, for the same transcendent Lord is Lord of all and bestows riches upon all who call him, and makes all one in Christ Jesus.
And this Lord who infinitely transcends his creation shouts through it. He shouts through icons, through every human love, through music, through storm and star. He is a God who so far transcends his Creation that he can enter into it, and a failure to love our neighbor is a failure to love God. Consider the parable of the sheep and the goats:
When the Son of man comes in his glory, and all the angels with him, then he will sit on his glorious throne. Before him will be gathered all the nations, and he will separate them one from another as a shepherd separates the sheep from the goats, and he will place the sheep at his right hand, but the goats at the left.
Then the King will say to those at his right hand, “Come, O blessed of my Father, inherit the kingdom prepared for you from the foundation of the world; for I was hungry and you gave me food, I was thirsty and you gave me drink, I was a stranger and you welcomed me, I was naked and you clothed me, I was sick and you visited me, I was in prison and you came to me.”
Then the righteous will answer him, “Lord, when did we see thee hungry and feed thee, or thirsty and give thee drink? And when did we see thee a stranger and welcome thee, or naked and clothe thee? And when did we see thee sick or in prison and visit thee?”
And the King will answer them, “Truly, I say to you, as you did it to one of the least of these my brethren, you did it to me.”
Then he will say to those at his left hand, “Depart from me, you cursed, into the eternal fire prepared for the devil and his angels; for I was hungry and you gave me no food, I was thirsty and you gave me no drink, I was a stranger and you did not welcome me, naked and you did not clothe me, sick and in prison and you did not visit me.”
Then they also will answer, “Lord, when did we see thee hungry or thirsty or a stranger or naked or sick or in prison, and did not minister to thee?”
Then he will answer them, “Truly, I say to you, as you did it not to one of the least of these, you did it not to me.”
And they will go away into eternal punishment, but the righteous into eternal life.
This transcendent God transcends his own Creation and transcends his own transcendence that his image is imprinted in every man, woman, and child, and we cannot fail to love our neighbor without failing ot love Christ God; we cannot mistreat our neighbor without mistreating Christ God. Christ so far transcends his own transcendence that there is not the faintest gap between our treatment of our least neighbors and our treatment of Christ God himself. The Pope is not Christ’s vicar on earth; our neighbor is Christ’s vicar on earth, and how we treat our neighbor is vicariously how we treat the Christ we will answer to on Judgment Day.
And who is our neighbor? Let’s have a slightly updated answer with disturbing clarity:
A certain religious scholar stood up and tested Jesus, saying, “Teacher, what shall I do to inherit eternal Life?”
He said to him, “What is written in the heart of the Bible? How do you read it?”
He answered, “You shall love the Lord your God with all your inward being, with all your soul, with all your strength, and with all your mind; and your neighbor as yourself.”
He said to him, “You have answered correctly. Do this, and you will live.”
But he, desiring to justify himself, asked Jesus, “Who is my neighbor?”
Jesus answered, “A certain man, an American, went into the worst part of town at night and was held up by thugs who took not only took his valuables but beat him and left him for dead, throwing him deep into a dark alley.
“By chance a police officer was walking down that way. When he saw the man, he gave the alley a wide berth and ran along.
“In the same way a boy scout passed through the place and gave the alley a wide berth.
“But when it got to the wee hours of the morning, he heard footsteps and a terrorist came along, and the man called out ‘Help me!’ from the dark alley in the worst part of town. And the terrorist was viscerally moved with compassion, came to him, and bandaged his wounds, using some of his clothing, and carried him to an emergency room.
“When the terrorist left, he took all of the money that he had with him, and gave it to the hospital, and said, ‘Take care of him. Whatever you spend beyond what I have given you, I will repay.’
“Now which of these three do you think seemed to be a neighbor to him who fell among the robbers?”
He said, “He who showed mercy on him.” Then Jesus said to him, “Go and do likewise.”
Do you believe God is transcendent? Go and do likewise to the transcendent Christ who approaches you in you neighbor.
