But to these discussions was added yet another, which, beginning in the early days of the Church, was handed down the ages until it had died out among the theologians of our own time.
In the first of the biblical accounts light is created and the distinction between day and night thereby made on the first day, while the sun and moon are not created until the fourth day. Masses of profound theological and pseudo-scientific reasoning have been developed to account for this—masses so great that for ages they have obscured the simple fact that the original text is a precious revelation to us of one of the most ancient of recorded beliefs—the belief that light and darkness are entities independent of the heavenly bodies, and that the sun, moon, and stars exist not merely to increase light but to "divide the day from the night, to be for signs and for seasons, and for days and for years," and "to rule the day and the night."
Of this belief we find survivals among the early fathers, and especially in St. Ambrose. In his work on creation he tells us: "We must remember that the light of day is one thing and the light of the sun, moon, and stars another—the sun by his rays appearing to add lustre to the daylight. For before sunrise the day dawns, but is not in full refulgence, for the sun adds still further to its splendour." This idea became one of the "treasures of sacred knowledge committed to the Church," and was faithfully received by the Middle Ages. The medieval mysteries and miracle plays give curious evidences of this: In a performance of the creation, when God separates light from darkness, the stage direction is, "Now a painted cloth is to be exhibited, one half black and the other half white." It was also given more permanent form. In the mosaics of San Marco at Venice, in the frescoes of the Baptistery at Florence and of the Church of St. Francis at Assisi, and in the altar carving at Salerno, we find a striking realization of it—the Creator placing in the heavens two disks or living figures of equal size, each suitably coloured or inscribed to show that one represents light and the other darkness. This conception was without doubt that of the person or persons who compiled from the Chaldean and other earlier statements the accounts of the creation in the first of our sacred books.(8)
(8) For scriptural indications of the independent existence of light and
darkness, compare with the first verses of the chapter of Genesis such
passages as Job xxxviii, 19,24; for the general prevalence of this early
view, see Lukas, Kosmogonie, pp. 31, 33, 41, 74, and passim; for the
view of St. Ambrose regarding the creation of light and of the sun, see
his Hexameron, lib. 4, cap. iii; for an excellent general statement,
see Huxley, Mr. Gladstone and Genesis, in the Nineteenth Century, 1886,
reprinted in his Essays on Controverted Questions, London, 1892,
note, pp. 126 et seq.; for the acceptance in the miracle plays of the
scriptural idea of light and darkness as independent creations, see
Wright, Essays on Archeological Subjects, vol. ii, p.178; for an
account, with illustrations, of the mosaics, etc., representing this
idea, see Tikkanen, Die Genesis-mosaiken von San Marco, Helsingfors,
1889, p. 14 and 16 of the text and Plates I and II. Very naively the
Salerno carver, not wishing to colour the ivory which he wrought, has
inscribed on one disk the word "LUX" and on the other "NOX." See also
Didron, Iconographie, p. 482.
Thus, down to a period almost within living memory, it was held, virtually "always, everywhere, and by all," that the universe, as we now see it, was created literally and directly by the voice or hands of the Almighty, or by both—out of nothing—in an instant or in six days, or in both—about four thousand years before the Christian era—and for the convenience of the dwellers upon the earth, which was at the base and foundation of the whole structure.
But there had been implanted along through the ages germs of another growth in human thinking, some of them even as early as the Babylonian period. In the Assyrian inscriptions we find recorded the Chaldeo-Babylonian idea of AN EVOLUTION of the universe out of the primeval flood or "great deep," and of the animal creation out of the earth and sea. This idea, recast, partially at least, into monotheistic form, passed naturally into the sacred books of the neighbours and pupils of the Chaldeans—the Hebrews; but its growth in Christendom afterward was checked, as we shall hereafter find, by the more powerful influence of other inherited statements which appealed more intelligibly to the mind of the Church.
Striking, also, was the effect of this idea as rewrought by the early Ionian philosophers, to whom it was probably transmitted from the Chaldeans through the Phoenicians. In the minds of Ionians like Anaximander and Anaximenes it was most clearly developed: the first of these conceiving of the visible universe as the result of processes of evolution, and the latter pressing further the same mode of reasoning, and dwelling on agencies in cosmic development recognised in modern science.
This general idea of evolution in Nature thus took strong hold upon Greek thought and was developed in many ways, some ingenious, some perverse. Plato, indeed, withstood it; but Aristotle sometimes developed it in a manner which reminds us of modern views.
Among the Romans Lucretius caught much from it, extending the evolutionary process virtually to all things.
In the early Church, as we have seen, the idea of a creation direct, material, and by means like those used by man, was all-powerful for the exclusion of conceptions based on evolution. From the more simple and crude of the views of creation given in the Babylonian legends, and thence incorporated into Genesis, rose the stream of orthodox thought on the subject, which grew into a flood and swept on through the Middle Ages and into modern times. Yet here and there in the midst of this flood were high grounds of thought held by strong men. Scotus Erigena and Duns Scotus, among the schoolmen, bewildered though they were, had caught some rays of this ancient light, and passed on to their successors, in modified form, doctrines of an evolutionary process in the universe.
