Macrina was not only the sister of Saints Basil and Gregory, but was the matriarch of the first Christian "salon" that established the standard for monasticism in the Eastern church. The section below is from the
New Advent encyclopedia:
Born about 330; died 379. She was the eldest child of Basil and Elder Emmelia, the granddaughter of St. Macrina the Elder, and the sister of the Cappadocian Fathers, Sts. Basil and Gregory of Nyssa. She received an excellent intellectual training, though one based more on the study of the Holy Bible than on that of profane literature. When she was but twelve years old, her father had already arranged a marriage for her with a young advocate of excellent family. Soon afterwards, however, her affianced husband died suddenly, and Macrina resolved to devote herself to a life of perpetual virginity and the pursuit of Christian perfection. She exercised great influence over the religious training of her younger brothers, especially St. Peter, afterwards Bishop of Sebaste, and through her St. Gregory received the greatest intellectual stimulation. On the death of their father, Basil took her, with their mother, to a family estate on the River Iris, in Pontus. Here, with their servants and other companions, they led a life of retirement, consecrating themselves to God. Strict asceticism, zealous meditation on the truths of Christianity, and prayer were the chief concerns of this community. Not only the brothers of St. Macrina but also St. Gregory of Nazianzus and Eustathius of Sebaste were associated with this pious circle and were there stimulated to make still further advances towards Christian perfection. After the death her mother Emmelia, Macrina became the head of this community, in which the fruit of the earnest Christian life matured so gloriously.
