Because of the days' focus on nature, they are also traditional times for women to pray for children and safe deliveries.
To Autolycus Book I, Chapters V and VI
By Theophilus, Bishop of Antioch, ca. A.D. 160
For as the soul in man is not seen, being invisible to men, but is perceived through the motion of the body, so God cannot indeed be seen by human eyes, but is beheld and perceived through His providence and works. For, in like manner, as any person, when he sees a ship on the sea rigged and in sail, and making for the harbour, will no doubt infer that there is a pilot in her who is steering her; so we must perceive that God is the governor [pilot] of the whole universe, though He be not visible to the eyes of the flesh, since He is incomprehensible. For if a man cannot look upon the sun, though it be a very small heavenly body, on account of its exceeding heat and power, how shall not a mortal man be much more unable to face the glory of God, which is unutterable? For as the pomegranate, with the rind containing it, has within it many cells and compartments which are separated by tissues, and has also many seeds dwelling in it, so the whole creation is contained by the spirit of God, and the containing spirit is along with the creation contained by the hand of God. As, therefore, the seed of the pomegranate, dwelling inside, cannot see what is outside the rind, itself being within; so neither can man, who along with the whole creation is enclosed by the hand of God, behold God. Then again, an earthly king is believed to exist, even though he be not seen by all; for he is recognised by his laws and ordinances, and authorities, and forces, and statues; and are you unwilling that God should be recognised by His works and mighty deeds?
Consider, O man, His works -- the timely rotation of the seasons, and the changes of temperature; the regular march of the stars; the well-ordered course of days and nights, and months, and years; the various beauty of seeds, and plants, and fruits; and the divers species of quadrupeds, and birds, and reptiles, and fishes, both of the rivers and of the sea; or consider the instinct implanted in these animals to beget and rear offspring, not for their own profit, but for the use of man; and the providence with which God provides nourishment for all flesh, or the subjection in which He has ordained that all things subserve mankind. Consider, too, the flowing of sweet fountains and never-failing rivers, and the seasonable supply of dews, and showers, and rains; the manifold movement of the heavenly bodies, the morning star rising and heralding the approach of the perfect luminary; and the constellation of Pleiades, and Orion, and Arcturus, and the orbit of the other stars that circle through the heavens, all of which the manifold wisdom of God has called by names of their own. He is God alone who made light out of darkness, and brought forth light from His treasures, and formed the chambers of the south wind, and the treasure-houses of the deep, and the bounds of the seas, and the treasuries of snows and hail-storms, collecting the waters in the storehouses of the deep, and the darkness in His treasures, and bringing forth the sweet, and desirable, and pleasant light out of His treasures; "who causeth the vapours to ascend from the ends of the earth: He maketh lightnings for the rain;" who sends forth His thunder to terrify, and foretells by the lightning the peal of the thunder, that no soul may faint with the sudden shock; and who so moderates the violence of the lightning as it flashes out of heaven, that it does not consume the earth; for, if the lightning were allowed all its power, it would burn up the earth; and were the thunder allowed all its power, it would overthrow all the works that are therein.
