Let, then, the life of Mary be as it were virginity itself, set forth in a likeness, from which, as from a mirror, the appearance of chastity and the form of virtue is reflected. From this you may take your pattern of life, showing, as an example, the clear rules of virtue: what you have to correct, to effect, and to hold fast.
The first thing which kindles ardour in learning is the greatness of the teacher. What is greater than the Mother of God? What more glorious than she whom Glory Itself chose? What more chaste than she who bore a body without contact with another body? For why should I speak of her other virtues? She was a virgin not only in body but also in mind, who stained the sincerity of its disposition by no guile, who was humble in heart, grave in speech, prudent in mind, sparing of words, studious in reading, resting her hope not on uncertain riches, but on the prayer of the poor, intent on work, modest in discourse; wont to seek not man but God as the judge of her thoughts, to injure no one, to have goodwill towards all, to rise up before her elders, not to envy her equals, to avoid boastfulness, to follow reason, to love virtue. When did she pain her parents even by a look? When did she disagree with her neighbours? When did she despise the lowly? When did she avoid the needy? Being wont only to go to such gatherings of men as mercy would not blush at, nor modesty pass by. There was nothing gloomy in her eyes, nothing forward in her words, nothing unseemly in her acts, there was not a silly movement, nor unrestrained step, nor was her voice petulant, that the very appearance of her outward being might be the image of her soul, the representation of what is approved. For a well-ordered house ought to be recognized on the very threshold, and should show at the very first entrance that no darkness is hidden within, as our soul hindered by no restraints of the body may shine abroad like a lamp placed within.
Why should I detail her spareness of food, her abundance of services—the one abounding beyond nature, the other almost insufficient for nature? And there were no seasons of slackness, but days of fasting, one upon the other. And if ever the desire for refreshment came, her food was generally what came to hand, taken to keep off death, not to minister to comfort. Necessity before inclination caused her to sleep, and yet when her body was sleeping her soul was awake, and often in sleep either went again through what had been read, or went on with what had been interrupted by sleep, or carried out what had been designed, or foresaw what was to be carried out.
She was unaccustomed to go from home, except for divine service, and this with parents or kinsfolk. Busy in private at home, accompanied by others abroad, yet with no better guardian than herself, as she, inspiring respect by her gait and address, progressed not so much by the motion of her feet as by step upon step of virtue. But though the Virgin had other persons who were protectors of her body, she alone guarded her character; she can learn many points if she be her own teacher, who possesses the perfection of all virtues, for whatever she did is a lesson. Mary attended to everything as though she were warned by many, and fulfilled every obligation of virtue as though she were teaching rather than learning.
Such has the Evangelist shown her, such did the angel find her, such did the Holy Spirit choose her. Why delay about details? How her parents loved her, strangers praised her, how worthy she was that the Son of God should be born of her. She, when the angel entered, was found at home in privacy, without a companion, that no one might interrupt her attention or disturb her; and she did not desire any women as companions, who had the companionship of good thoughts. Moreover, she seemed to herself to be less alone when she was alone. For how should she be alone, who had with her so many books, so many archangels, so many prophets?
And so, too, when Gabriel visited her (Lk. 1:28). did he find her, and Mary trembled, being disturbed, as though at the form of a man, but on hearing his name recognized him as one not unknown to her. And so she was a stranger as to men, but not as to the angel; that we might know that her ears were modest and her eyes bashful. Then when saluted she kept silence, and when addressed she answered, and she whose feelings were first troubled afterwards promised obedience.
And holy Scripture points out how modest she was towards her neighbours. For she became more humble when she knew herself to be chosen of God, and went forthwith to her kinswoman in the hill country, not in order to gain belief by anything external, for she had believed the word of God. “Blessed,” she said, “art thou who didst believe” (Lk. 1:56). And she abode with her three months. Now in such an interval of time it is not that faith is being sought for, but kindness which is being shown. And this was after that the child, leaping in his mother’s womb, had saluted the mother of the Lord, attaining to reason before birth.
And then, in the many subsequent wonders, when the barren bore a son, the virgin conceived, the dumb spake, the wise men worshipped, Simeon waited, the stars gave notice. Mary, who was moved by the angel’s entrance, was unmoved by the miracles. “Mary,” it is said, “kept all these things in her heart” (Lk. 2:19). Though she was the mother of the Lord, yet she desired to learn the precepts of the Lord, and she who brought forth God, yet desired to know God.
And then, how she also went every year to Jerusalem at the solemn day of the passover, and went with Joseph. Everywhere is modesty the companion of her singular virtues in the Virgin. This, without which virginity cannot exist, must be the inseparable companion of virginity. And so Mary did not go even to the temple without the guardianship of her modesty.
This is the likeness of virginity. For Mary was such that her example alone is a lesson for all. If, then, the author displeases us not, let us make trial of the production, that whoever desires its reward for herself may imitate the pattern. How many kinds of virtues shine forth in one Virgin! The secret of modesty, the banner of faith, the service of devotion, the Virgin within the house, the companion for the ministry, the mother at the temple.
Oh! how many virgins shall she meet, how many shall she embrace and bring to the Lord, and say: “She has been faithful to her espousal, to my Son; she has kept her bridal couch with spotless modesty.” How shall the Lord Himself commend them to His Father, repeating again those words of His: “Holy Father, these are they whom I have kept for Thee, on whom the Son of Man leant His head and rested; I ask that where I am there they may be with Me” (Jn. 17:24). And if they ought to benefit not themselves only, who lived not for themselves alone, one virgin may redeem her parents, another her brothers. “Holy Father, the world hath not known Me, but these have known Me, and have willed not to know the world” (Jn 17:25).
What a procession shall that be, what joy of applauding angels when she is found worthy of dwelling in heaven who lived on earth a heavenly life! Then too Mary, (in Hebrew Miriam) taking her timbrel, shall stir up the choirs of virgins, singing to the Lord because they have passed through the sea of this world without suffering from the waves of this world (Ex. 15:20). Then each shall rejoice, saying: “I will go to the altar of God; to God Who maketh my youth glad” (Ps. 43:4); and, “I will offer unto God thanksgiving, and pay my vows unto the Most High” (Ps. 50 :14).
Nor would I hesitate to admit you to the altars of God, whose souls I would without hesitation call altars, on which Christ is daily offered for the redemption of the body. For if the virgin’s body be a temple of God, what is her soul, which, the ashes, as it were, of the body being shaken off, once more uncovered by the hand of the Eternal Priest, exhales the vapour of the divine fire. Blessed virgins, who emit a fragrance through divine grace as gardens do through flowers, temples through religion, altars through the priest.
