It is an ancient and very trustworthy tradition that the Blessed Virgin was thus solemnly offered in the Temple to God at the age of three by Her parents, Saint Anne and Saint Joachim.
From St. Ambrose:
Let the life of the blessed Mary be ever present to you, in which, as in a mirror, the beauty of chastity and form of virtue shine forth. She was a virgin not only in body, but in mind, who never sullied the pure affection of her heart by unworthy feelings. She was humble of heart, serious in her conversation, prudent in her counsels, fonder of reading than of speaking. She placed her confidence rather in the prayer of the poor, than in the uncertain riches of this world. She was ever intent in her occupations, reserved in her conversation, and accustomed to make God, rather than man, the witness of her thoughts...her very appearance was the picture of her mind and the figure of piety.(To see more stain glass windows as above click on the words "stain glass window".)
