The bright moon is more related to Our Lady than to God.
‘During the whole first week of the creation of the world and its contents Lucifer and the demons were occupied in machinations and projects of wickedness against the Word, who was to become incarnate, and against the Woman [who was to crush his head (Gen. 3,15)] of whom He was to be born and made man. On the first day, which corresponds to Sunday, were created the angels. Laws and precepts were given to them, for the guidance of their actions. The bad ones disobeyed and transgressed the mandates of the Lord. By divine providence and disposition then succeeded all the other events, which have been recorded above, up to the morning of the second day, corresponding to Monday, on which Lucifer and his hosts were driven and hurdled into hell. The duration of these days corresponds in the small periods, or delays, which intervened between their creation, activity, conquest and fall or glorification…. ‘The most High looked upon His Son, and upon His most holy Mother as models, produced in the culmination of his wisdom and power, in order that They serve as prototypes according to which He was to copy the whole human race. He created also the necessary material beings required for human life, but with such wisdom that some of them act as symbols, to represent, in a certain way these two Beings. On this account He made the luminaries of heaven, the sun and the moon (Gen. 1,16) so that in dividing the day and the night, they might symbolise the Sun of Justice, Christ, and His holy mother, who is beautiful as the moon (Cant: 6, 9) [WHO IS SHE THAT COMETH FORTH AS THE MORNING RISING, FAIR AS THE MOON, BRIGHT AS THE SUN, TERRIBLE AS AN ARMY SET IN ARRAY] for these two divide the day of grace and the night of sin.
The sun illuminates the moon; and both, together with the stars of the firmament, illume all other creatures within the confines of the universe …. He created the rest of the beings and added to their perfection, because they were to be submissive to Christ and the most holy Mary and through them to the rest of men.' ---Mary of Agreda (1602-1665) ‘The Mystical City of God’ or ‘The Divine History and Life of the Virgin Mother of God.’
The sky was created by God to demonstrate his omnipotence to mankind. And so it did until Copernicus, Galileo and Isaac Newton whose so-called law of gravitation “took from God that direct action on his works so constantly ascribed to him in Scripture and transferred it to material mechanism,” and that he “substituted gravitation for Providence.”
But now that their naturalism has been crushed in recent times by Catholic and Protestant scholars, the Moon should again remind us Catholics of The Virgin Mary, Mother of God every time we see it in all its splendor. Over the last few days the Moon reached its most brightest and closest to earth for many years, telling us Mary is watching from heaven always.
