2. So much for the substance of St. Paul's teaching; and now what is to be said as to its sources? St. Paul states his doctrine of original sin as if it were a commonplace which he could assume and argue from. Now the Book of Genesis certainly spoke of a primaeval disobedience in our first parents, and of the infliction on them, as a penalty for their disobedience, of conditions of strife and pain and death. But the idea of the transmission of sinfulness does not seem to be suggested. Moreover, this narrative made remarkably little impression on the Old Testament literature as a whole[[9]]. The doctrine, however, of the introduction of death through the temptation and sin of Adam and Eve is found again in the apocryphal literature: thus, 'God created man for incorruption, ... but by the envy of the devil death entered into the world[[10]].' From a woman was the beginning of sin; and because of her we all die[[11]].' Unto Adam thou gavest thy one commandment, which he transgressed, and immediately thou appointedst death for him and in his generations; and there were born of him nations and tribes, peoples and kindreds, out of number[[12]].' 'Adam sinned, and death was decreed against those who should be born[[13]].' This was also the prevalent doctrine of the Rabbis represented in the Talmud. The idea of an inheritance of moral corruption—but not specially associated with Adam's fall—may be found in the cry of the Psalmist, 'In sin hath my mother conceived me!' perhaps also in other passages of the Old Testament, and in our Lord's teaching, as recorded both by the Synoptists and in St. John's Gospel[[14]]; but as connected with Adam's sin it does not, so far as can be ascertained, appear for certain in Jewish literature till we get to the Second Book of Esdras, a Jewish Apocalypse later than St. Paul. There it is taught that there was originally a seed of evil, 'a wicked heart,' in Adam as he was created, side by side with the good in him, and that he by his sin gave it preponderance in the race[[15]]—a form of teaching not by any means identical with St. Paul's. On the whole, then, it remains a matter of some doubt what exactly was the source whence St. Paul got the certainty and completeness of his doctrine of 'the fault and corruption of the nature of every man that naturally is ingendered of the offspring of Adam.'
3. The more important question for us, however, is not whence St. Paul derived the materials for his teaching, but whether it is true—whether it can hold in the light of modern anthropology. And to this question only a partial answer—the answer that appears to be most necessary—will be attempted here[[16]].
We are in our generation rightly anxious if we are asked to accept any professedly historical statement for which we feel the evidence is doubtful. We know that from the point of view of history the origin of our human species is lost in dense obscurity and uncertainty. And it relieves many consciences to realize that, if St. Paul states his argument in a form which implies the historical character of the narrative in Genesis iii, all that is necessary for his argument is to assume (1) that the human race is organically one, and can be dealt with as one; (2) that sin is universal in our race; (3) that at least the sting or curse or bondage of death is due to sin. If we realize that this is all that need be allowed in order to give us full fellowship in St. Paul's religious teaching, we shall be able to investigate the further truth of his teaching, from a scientific and historical point of view, with a free mind.
And the three propositions stated above are not reasonably open to doubt, (1) That our race is one species, and derived from one source, is the conclusion of the modern ethnologist as much as of St. Paul[[17]]. The general theory of evolution has effectively counteracted the previous tendency to postulate the existence of various independent races of men.
(2) There are many professors of psychology who deny the existence of moral freedom and consequently of sin in St. Paul's sense at all. As I have already pointed out, this is the real battle-ground between theology and science. But granted the reality of moral freedom and of sin, i.e. of something which need not and ought not to have been committed, it is impossible to deny that, below the innumerable sins of which human history is full, there exists deep in our nature an 'ineradicable taint'—a morbid tendency to do wrong—a bias or propensity to evil—which is the heritage of our race; which indeed men may become unconscious of by acquiescing in sin, but of which they become painfully conscious again as soon as they are awakened to a moral ideal. The late Dr. Mozley collected a remarkable series of passages from what he calls 'worldly philosophers and poets'—notably Byron and Shelley—testifying to the belief in universal sin[[18]]. This of course we may say is only the inheritance of animal tendencies from an animal ancestry; but if so, it is exactly what our higher spiritual nature might and ought to have subdued long ago and brought into subjection. Its presence with us and in us now is the result of sins innumerable—innumerable wilful preferences of the lower to the higher nature, which have let it loose and given it force. It is, in the strictest sense, the inheritance of sin in the race.
(3) The New Testament frequently reiterates the assertion that Christ has robbed death of its sting or delivered men from its bondage. And this is also expressed (both by St. Paul and by our Lord Himself, as reported by St. John) by saying that Christ has 'abolished death[[19]]' or that the believer shall never die[[20]]. But if Christ has abolished death, then there is at least a certain sense in which sin has been the cause of death. The essence of death, according to this use of the word, lies not in the physical transition from one state of existence to another, which is no more death than it is birth. Death means destruction, ruin and collapse. And what is called death—the death of the present body—has only gathered about it such terrible associations because men have become corrupt, and godless and therefore short-sighted in their estimate of life. In the moral sense then in which Christ abolished death, sin certainly introduced it for man.
Now there is, I think, reason to believe more exactly with St. Paul than is involved in these three positions[[21]]. But I feel sure that any one who accepts these three positions—no one of which any believer in God and morality can well reject—may find himself in complete practical fellowship with St. Paul's religious thought and with the whole argument of this epistle.
Humanity, in spite of all its racial differences, is a great unity: it is, if not 'of one' individual, yet 'of one blood,' and it is as a whole infected with sin; this is in effect the doctrine of the 'old Adam.' And because it is one, and universally tainted, therefore Christ can deal with it as one, in order to accomplish its restoration. And all St. Paul's argument holds good. God has made humanity one, and so one that what each does tends to affect all. Thus it has come about that the force of sin—the wilful refusal of the higher life and choice of the lower—has passed in its effects into the moral fibre of our race, and weakened and corrupted the whole. God tolerates this, for man must be, and must be dealt with as being, one and free. But God desires the well-being of man. He hates sin. It has all but baffled His purpose for man. Therefore, if He has tolerated the use which sin has made of the organic unity of the human race, He can much more be trusted to use that same unity for the purpose of good. As man is one in sin, so we can be one in righteousness: as the old Adam has been universal, so can the new. As sin has been propagated physically, so Christ can spiritually propagate the new manhood. The forces of recovery shall spread and permeate more radically than the forces of evil, and shall finally triumph.
Of course, in view of all the deep racial differences between, for instance, Europeans, Chinamen, and the races of India, to believe in the unity of humanity in any real sense at all is a great act of faith. But it is an act of faith in which science encourages us, and not least the comparative study of religions. Our religious instincts and faculties are found in very different degrees of development, but they are fundamentally the same. And it is an act of faith to which Christ and Christianity fundamentally commit us, though it is probably true to say that since New Testament times the brotherhood of men has been practically found to be the most difficult of Christian dogmas.
4. It is not inopportune, in view of recent controversy, to call attention in this connexion to the fact that St. Paul's doctrine of Christ as the second Adam of necessity involves in some form His miraculous birth. St. Paul indeed says nothing about Christ's nativity of the Virgin as an event in history; but he conceives of the Christ as a fresh start in manhood, a new man, who yet drew the substance of His manhood from the old stock, for He was 'born of a woman,' and 'of the seed of David.' There is thus physical continuity between the old Adam and Christ, and yet, from the moral point of view, the break is complete. The inheritance of sin which has followed, and must according to natural law follow, physical descent, is quite cut off. Christ is man of our old substance and yet new man, wholly free from any taint of sin. This involves a new creative act upon the manhood of Christ in its source. It involves something strictly miraculous conditioning the continuity of His descent from David. There is continuity, and yet a break in continuity. And this is exactly what the strongly-attested fact of the Virgin birth—whatever be the physiological account which is to be given of it—is calculated to supply. It presents us with a Christ born of a woman, of the substance of our nature, and yet only so constituted by a new creative act of God.
