At the end of the third letter, Colet naturally stumbles on the difficulty of explaining how, if all things were created _at once_ 'in the beginning,' before all time, Moses could say at the end of each stage of his description of the creation, 'and the evening and the morning were the first, second, third, &c. _day_:' and, after fairly losing himself in an attempt to solve this difficulty, he ends by urging Radulphus to leave these obscure points, which are practically beyond our range, and to bear in mind throughout what he had before spoken of, viz. that whilst Moses wished to speak in a manner not unworthy of God, he wished, at the same time, in matters within the knowledge of the common people, to satisfy the common people, and to keep to the order of things; above all things, to lead the people on to the religion and worship of the one God.[116] 'The chief things known to the common people were sky, land and water, stars, fishes, beasts, and so he deals with them. He arranged them in six days; _partly_ because the things which readily occur to men's minds are six in number:[117]--(1) What is above the sky, (2) sky itself, (3) land, surrounded by water, and productive of plants, (4) sun and moon in the sky, (5) fish in the water, (6) beasts inhabiting earth and air, and _man_, the inhabitant of the whole universe;--and _partly_ and _chiefly_, that he might lead the people on to the imitation of God, whom, _after the manner of a poet_, he had pictured as working for six days and resting the seventh, so that they also should devote every seventh day to rest and to the contemplation of God and to worship.'[118] 'For, beyond all doubt,' Colet proceeds to say, 'Moses never would have put forward a number of days for any other purpose than that, by this most useful and most wise poetic figment, the people might be provoked to imitation by an example set before them, and so ending their daily labours on the sixth day, spend the seventh in the highest contemplation of God.'[119] Colet ends his third letter by saying, 'Thus you have my notions upon the work of the third day, but what to make of it I know not. It is enough, as I have said, to have touched upon it lightly. Farewell.'
