It is the divine maternity of Mary which explains both her perfect excellence and her perfect holiness. It is the key to all her gifts and privileges. For the excellence of each creature is to be found in the degree in which it resembles its Creator. . . . Mary was made as like to Him [Christ], as being a mere creature, she could be made. For, having no earthly father, our Lord bore the human likeness of His mother in all His features. Or rather, she bore His likeness…
For He was formed by the Holy Ghost of her flesh. And His blood, that saving blood which redeemed the world, was taken from her heart. And whilst the Godhead dwelt bodily in Him, He, for nine months, dwelt bodily in her. And all that time . . . the stream which nourished the growth of life in Jesus flowed from the heart of Mary, and, at each pulsation, flowed back again, and re-entered His Mother’s heart, enriching her with His divinest spirit. How pregnant is that blood of His with sanctifying grace, one drop of which might have redeemed the world. . . . Next to that union by which Jesus is God and man in one person, there is no union so intimate as that of a mother with her child. . . .( William Ullathorne)
