Three Ideas
In this section, the Sermon on the Mount concludes with three ideas. Let's examine each of them one at a time.
The Narrow Way
Jesus tells us that his way is a narrow one, and few will find it. To put it more plainly: Jesus's path is difficult. And if you've been paying attention so far, you know just how true that is.
This statement apparently causes quite a bit of agonizing in some corners of the Christian world. I unaware of this until I went looking for commentaries on this verse, but it makes sense. For many Christians, Heaven is a physical place which some of us will make it when we die. The rest of us are going to another place, a place of fire and torment without end. If this is the case, then these verses are terrifying. Jesus is basically saying "Most of you are going to be sent to Hell, so good luck with that."
And so, many Christians simply choose to ignore these lines, and believe that everyone or almost everyone is going to Heaven. Others choose to take them rather more literally, and assume that God really is going to send most people to Hell. The former type is preferable to the latter, who are frankly creepy, but in my view both are wrong.
Reincarnation
The Phaedo is Plato's account of the last hours of the life of his teacher Socrates. The Phaedo opens with Socrates, in prison, about to be given the poison which will end his life. Several of his students are there, and they are full of fear and mourning, but Socrates tells them that he isn't afraid, and they shouldn't be upset. Instead, he says, every true philosopher will make haste to follow him. He then gives an account of the immortality of the soul and its experiences after death.
For Socrates, there are several options, once the soul is led by its guardian spirit into the Underworld. There is indeed what we would call Heaven and Hell, and Heaven is a place where the just are rewarded, and Hell is a place where the wicked are punished. Some-- in particular, those who have committed mass killings or who have committed blasphemy-- are sent to Hell (or, rather, Tartarus) for good, at least apparently. Most, however, will have a chance to return, once they have been purified. The just go to a place of reward, but this isn't permanent either-- it's merely a natural reward for their good deeds.
Eventually, all who have been judged in the Underworld return to Earth. Some return in human form, but others must return as animals:
But besides these, there is another option.
Socrates tells us that there is a true Heaven, above our physical world. There the air that we breathe is as dense and dark as the ocean is, and we appear to the people who live there like bottom-feeding fish, dwelling in the mud.
The practice of Philosophy is the way to this True Heaven; attaining it, one is no longer required to return to the Earth. For this reason Socrates, on the eve of his execution, tells his disciples to make haste to follow after him.
Does all of this sound familiar? Just the same idea is found in Buddhism, expressed (in a rather more concise form) by the Buddha himself in the Dhammapada:
For both Plato and Buddha, the end goal is the transcendence of wheel of birth, death and rebirth-- even very enjoyable rebirths. But are they right?
Moral Monstrosity
Let's put the matter as plainly as we can.
If it really is the case, as many Christians hold, that we get a single chance at life, at the end of which we are judged; and that the judgment is final, with only two possible results, a Heaven of everlasting bliss or a Hell of eternal torment; then Christianity is a moral monstrosity. It's a stupid, petty, childish system of psychological torture unfit to be taken seriously by any adult.
We've now come to the end of the Sermon on the Mount, which forms the core of Jesus's teaching. Does he seem like the kind of man who would teach such nonsense? Does that seem like what he is saying here?
An even better question-- Even if Jesus was saying that, does it seem true?
By Their Fruits Shall Ye Know Them
It's all so confusing, isn't it? there are so many spiritual paths, and paths within paths, all making claims which sound plausible enough. How are we to judge between them?
Fortunately, Jesus now gives us a very simple test by which we can know the truth or falsehood of any spiritual teaching whatsoever.
That test is this:
By their fruits shall ye know them.
For any spiritual path-- indeed, for any teaching or practice whatsoever-- if you want to know whether it works and how it works, all you need to do is look at what kind of people it produces.
Are they wishy-washy, preaching kindness and tolerance but with no backbone and quick to bow to whatever trend passes through the larger culture? Or are they rigid and angry, brimming over with hostility and with barely-concealed sexual constipation? Or are they kind and good, but with a deep reserve of strength and unwillingness to tolerate falsehood? Different forms of Christianity, and different spiritual paths outside of Christianity, can produce all three of these characters. Which seems best to you, and which does Jesus's Narrow Way seem most likely to produce, if it is truly practiced?
The Will of the Father
Remember.
The Father is the Good Itself, the Eternal Source of all existence. Heaven is the realm of the eternal Ideas, the spiritual forms which precede and govern the worlds of concrete thought and, finally, of matter. The Kingdom of Heaven is the community of all those souls which have raised themselves up to the presence of the Father, and now exist entirely on the level of the eternal Ideas. It is also that community of souls as they interact with one another in material form as they sojourn here on the Earth.
The Will of the Father is that we be united to Him; it is also, at the same time, and without contradiction that we become precisely those beings which he intended us to be when he brought us forth into manifestation. As the Father is eternal and his Will is eternal, to unite ourselves to Him is akin to building a house with strong foundations; the ceaseless movements of impermanence here in the world of Becoming will not change us. To fail to do so is to build a house on a foundation of sand. The winds of the world will blow and we will fall.
