There is no such thing as a man (homo sapiens) without religion, unless of course we count the victims of dementia. All human beings have an overall understanding, however tentative, of reality as a whole; a framework, instinctive or reasoned, that allows them to understand how things connect to each other, how they form a whole, what their meaning and goal and usefulness are.
That is what religion is. Every other definition is clearly fallacious. If we envisage it, for instance, as the search for what is morally or aesthetically highest, then a number of proven religions simply don’t make it. The ancient Aztecs sacrificed human beings in their thousands and in circumstances of the most horrible depravity; as for aesthetic excellence, it would be a curious taste that found it in their gods with their skeletal faces and corpse-like bodies. (There is indeed beauty of a sort in ancient Mexican art, but it is in my view to be found in the whole, in the design of the pyramids, the discs, the slabs of stone, rather than in the individual that populate them. You might say that it is a synthesis that builds up an overall beauty from details of horror.)
Was that not a religion, then? Heck yes! The Aztecs were convinced that the universe had the shape they envisaged, and, being the kind of place it was, it demanded that many human beings should be sacrificed to it. In doing so, the Aztecs fulfilled the duties that their vision of the world involved. Other religions have postulated, for instance, that there is a fundamental ontological difference between believers and unbelievers, such as that the unbelievers are so far out of the proper human level that their proper position is as slaves and prey to the believers; or that different classes of human beings amount to different kinds of being, so distant from each other that to think of sexual congress between them is disgusting, as we would think of sexual congress with a dog. (That is not so hard to understand if we turn from caste to race. The complex of taboos and horrified fascination that drove the destructive relationship between whites and blacks in the old south had its centre in sexual ideas, so that the idea of a black man possessing a white woman was both compulsive and terrible. That is how believers in caste regard sexual congress between a higher and a lower caste.)
It follows that religion does not have a dependent relationship on morality; it does not search for or obey a morality already made. This, if they were able to formulate enough, would be the most widespread stupid idea about religion of our day. People would say - and say with a straight face - that the practices of this or that religion which strike them as immoral cannot be to do with “what religion really is”, or even with “what that religion really is”. The general idea is that real religion must inevitably be moral; which is mistaking the stream with its source. Religion defines morality, not the other way around. The people who declare war on the world in the name of their God; the people who butcher men on high altars and raise their still-beating bloody hearts to heaven; the people who will eagerly commit murder rather than allow sexual congress between different castes or races; all these people are doing the right thing according to their own religion. They are following the dictates that teach that, because the universe is a certain kind of thing, because mankind and the internal divisions of mankind are a certain kind of thing, because the world contains certain relationships, therefore those acts are objectively good and dutiful. The Aztec priests were certain that, if their service to the gods with its thousands of butchered dead were to cease, the universe would collapse. The end of their drive came not just because the Spanish put an end to the sacrifices and the universe did not in fact collapse - that could have been remedied in any of a hundred ways (including to claim that the arrival of the Spanish had itself been the expected collapse, that had destroyed the world as they knew it). What put an end to it was a different view of reality and of God, the view taken in Cortez’s hulls by his Franciscan preachers and their books.
Religion makes morality. I will deal later (if any of my readers remind me) with the relationship of this with CS Lewis’ famous argument for an underlying universal moral sense or “tao”. For the present I will only say this: that religion as an understanding of reality - a philosophy of reality, as I call it - is, like any other aspects of philosophy, an understanding of reality. Reality is what it claims to understand, but reality comes first. And so, if religion delivers a structured understanding of morality, we have to understand that a moral impulse is a part of reality, a part, that is, of human nature. Religious doctrine, however, varies to such an extent that what one religion declares true - in the field of morality, mind you - another declares false.
Compare, for instance, two capital religious texts, Galatians 3.28 (St.Paul says the same thing in the same terms in two other letters, but I shall use this one) and the
Purusa Sukta, RigVeda Hymn no.10.90 - but, like the Pauline verse, repeated in all the other Vedic collections. The interesting thing about these two passages is that they present almost the same religious image: a supernatural unity in the form of a man, in which exist at once, either all of creation, or the whole Church. The Purusha of the Vedic hymn is nothing else than The Man, cosmic unity in the image of a man, who is divided so that all of creation might have individual existence. All concrete things are found in him. In St.Paul, however, it is the Church that is at one and the same time The Man - the body of the Son of Man: “Now ye are the Body of Christ” - 1Corinthians 12.27. And this is cosmic body of the Son of Man is a very articulated thing indeed - nearly as varied as the body of the Vedic Man:
St.Paul:
13For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit.
14For the body is not one member, but many.
15If the foot shall say, Because I am not the hand, I am not of the body; is it therefore not of the body?
16And if the ear shall say, Because I am not the eye, I am not of the body; is it therefore not of the body?
17If the whole body were an eye, where were the hearing? If the whole were hearing, where were the smelling?
18But now hath God set the members every one of them in the body, as it hath pleased him.
19And if they were all one member, where were the body?
20But now are they many members, yet but one body.
21And the eye cannot say unto the hand, I have no need of thee: nor again the head to the feet, I have no need of you.
22Nay, much more those members of the body, which seem to be more feeble, are necessary:
23And those members of the body, which we think to be less honourable, upon these we bestow more abundant honour; and our uncomely parts have more abundant comeliness.
24For our comely parts have no need: but God hath tempered the body together, having given more abundant honour to that part which lacked.
25That there should be no schism in the body; but that the members should have the same care one for another.
26And whether one member suffer, all the members suffer with it; or one member be honoured, all the members rejoice with it.
27Now ye are the body of Christ, and members in particular.
28And God hath set some in the church, first apostles, secondarily prophets, thirdly teachers, after that miracles, then gifts of healings, helps, governments, diversities of tongues.
RV 10.90:
6 When Gods prepared the sacrifice with Puruṣa as their offering,
Its oil was spring, the holy gift was autumn; summer was the wood.
7 They balmed as victim on the grass Puruṣa born in earliest time.
With him the Deities and all Sādhyas and Ṛṣis sacrificed.
8 From that great general sacrifice the dripping fat was gathered up.
He formed the creatures of-the air, and animals both wild and tame.
9 From that great general sacrifice Ṛcas and Sāma-hymns were born:
Therefrom were spells and charms produced; the Yajus had its birth from it.
10 From it were horses born, from it all cattle with two rows of teeth:
From it were generated kine, from it the goats and sheep were born.
11 When they divided Puruṣa how many portions did they make?
What do they call his mouth, his arms? What do they call his thighs and feet?
12 The Brahman was his mouth, of both his arms was the Rājanya made.
His thighs became the Vaiśya, from his feet the Śūdra was produced.
13 The Moon was gendered from his mind, and from his eye the Sun had birth;
Indra and Agni from his mouth were born, and Vāyu from his breath.
14 Forth from his navel came mid-air the sky was fashioned from his head
Earth from his feet, and from his car the regions. Thus they formed the worlds.
There are differences. St.Paul is in deadly earnest because he is addressing people who must be set straight here and now; the author of RV10.90 is calmly setting out an idea of the universe for people whose allegiance is not in doubt and whose individual salvation is not immediately his concern. But there are also subtler similarities: the Purusa must be offered as a sacrifice so that the worlds might exist; Jesus Christ, whose body is the Church, is also God as creator (“through Him all things were made”) and at one and the same time the ultimate victim in the ultimate sacrifice. Clearly these two complexes of ideas have much in common.
When it comes to societal morality, however, they contradict each other flatly. St.Paul stated clearly that, whatever the difference in offices and gifts, all members of the Church are fundamentally equal: “There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus.” And if there should be any doubt, "God hath tempered the body together, having given more abundant honour to that part which lacked, That there should be no schism in the body; but that the members should have the same care one for another." Specifically, it is the union of the Church with the sacrificed body of Jesus in the Eucharist that makes every Christian equal in dignity with every other. Conversely, the cosmic sacrifice of the Purusa creates, among all other separate and autonomous orders of things, the four Varnas or basic castes (the word “caste” in ordinary usage denotes a “jati”, which is a sub-group of the Varnas): “11 When they divided Puruṣa how many portions did they make?/ What do they call his mouth, his arms? What do they call his thighs and feet?/ 12 The Brahman was his mouth, of both his arms was the Rājanya made./ His thighs became the Vaiśya, from his feet the Śūdra was produced.” The Man, therefore, may be one, but men are many, and their differences are ontological, as much as those between Sun and Moon, thunderstorm and fire and wind, the air, the sky and the earth. (“13 The Moon was gendered from his mind, and from his eye the Sun had birth;/ Indra (the god of storms) and Agni (the god of fire) from his mouth were born, and Vāyu (the god of wind) from his breath./ 14 Forth from his navel came mid-air the sky was fashioned from his head/ Earth from his feet, and from his car the regions. Thus they formed the worlds.”) For a world to exist, such things as sky and sea, moon and sun, wind and fire, must have their own existence and be separate from each other; and for the same reason - the two groups of two stanzas balance each other and positively demand to be read as doublets of each other - holy men (brahmanas) and warriors (rajanya) and the mass of free men (vaisya) and the mass of serfs (sudra) must exist and be separate.
Since religion is the interpretation of reality, the philosophy of reality, it is at least terrifyingly difficult, and on the whole better left alone, to try and take a position outside religion and try to assess the religions in terms of a universal morality that can be found outside and above them. While the impulse to morality, like for that matter the fact of war, can be found in every society in the world, the way that it is conceptualized and formulated varies from religion to religion. Just as it is a matter of high morality for Christians to treat all men as equals, so it was a matter of high morality for the authors of the Mahabharata that the four Varnas should each recognize and perform their caste duties. That was one of the first thing that visiting ascetics asked noble kings, in particular the most just king Yudhisthira, when they honour their courts with a visit.
Ultimately such differences can be embraced by debate, though not necessarily undone - that would amount to conversion. But it is very important to accept that each person has his or her own religion, in the sense of his or her own view of existence; and that religion by its nature generates a picture of morality, gives the moral impulse a frame and a shape. There is therefore no more dangerous delusion than to pretend to judge and condemn someone else’s religion from the point of view of morality; and that is because the morality you invoke inevitably turns out to be that of your own religion. You therefore end up condemning the other guy’s religion on the grounds that it is not yours, and very likely he, not being necessarily any wiser than you, condemns yours because it is not his.
