St. Hilary of Poictiers reconciled the two conceptions as follows: "For, although according to Moses there is an appearance of regular order in the fixing of the firmament, the laying bare of the dry land, the gathering together of the waters, the formation of the heavenly bodies, and the arising of living things from land and water, yet the creation of the heavens, earth, and other elements is seen to be the work of a single moment." St. Thomas Aquinas drew from St. Augustine a subtle distinction which for ages eased the difficulties in the case: he taught in effect that God created the substance of things in a moment, but gave to the work of separating, shaping, and adorning this creation, six days.(5) (5) For Philo Judaeus, see his Creation of the World, chap. iii; for St. Augustine on the powers of numbers in creation, see his De Genesi ad Litteram iv, chap. ii; for Peter Lombard, see the Sententiae, lib. ii, dist. xv, 5; and for Hugo of St. Victor, see De Sacrementis, lib i, pars i; also, Annotat, Elucidat in Pentateuchum, cap. v, vi, vii; for St. Hilary, see De Trinitate, lib. xii; for St. Thomas Aquinas, see his Summa Theologica, quest lxxxiv, arts. i and ii; the passage in the Nuremberg Chronicle, 1493, is in fol. iii; for Vousset, see his Discours sur l'Histoire Universelle; for the sacredness of the number seven among the Babylonians, see especially Schrader, Die Keilinschriften und das Alte Testament, pp. 21,22; also George Smith et al.; for general ideas on the occult powers of various numbers, especially the number seven, and the influence of these ideas on theology and science, see my chapter on astronomy. As to medieaval ideas on the same subject, see Detzel, Christliche Ikonographie, Frieburg, 1894, pp. 44 and following. The early reformers accepted and developed the same view, and Luther especially showed himself equal to the occasion. With his usual boldness he declared, first, that Moses "spoke properly and plainly, and neither allegorically nor figuratively," and that therefore "the world with all creatures was created in six days." And he then goes on to show how, by a great miracle, the whole creation was also instantaneous. Melanchthon also insisted that the universe was created out of nothing and in a mysterious way, both in an instant and in six days, citing the text: "He spake, and they were made." Calvin opposed the idea of an instantaneous creation, and laid especial stress on the creation in six days: having called attention to the fact that the biblical chronology shows the world to be not quite six thousand years old and that it is now near its end, he says that "creation was extended through six days that it might not be tedious for us to occupy the whole of life in the consideration of it."
