Imitate Mary, holy mothers, who in her only dearly beloved Son set forth so great an example of maternal virtue; for neither have you sweeter children, nor did the Virgin seek the consolation of being able to bear another son. – Letters 63:111 (396 A.D).

St. Ambrose of Milan

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. – Virgins 2:2:6 (377 A.D).

The first thing that kindles ardor in learning is the greatness of the teacher. What is greater [to teach by example] 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 neighbors? When did she despise the lowly? When did she avoid the needy? – Virgins 2:2:7 (377 A.D).

Come, then, and search out your sheep, not through your servants or hired men, but do it yourself. Lift me up bodily and in the flesh, which is fallen in Adam. Lift me up not from Sarah but from Mary, a virgin not only undefiled, but a virgin whom grace had made inviolate, free of every stain of sin. – Commentary on Psalm 118, 22:30 (387 A.D).
