Much is said of the Church Fathers—but not as much of the Church Mothers. One often overlooked yet fiercely foundational mother of the Church is St. Macrina the Younger (ca. 327–379). Though she lived a largely hidden monastic life, her spiritual legacy resounds across centuries.

Born into a deeply devout family, Macrina was the eldest sister of St. Basil the Great, St. Gregory of Nyssa, and St. Peter of Sebaste—three brothers who went on to shape Christian theology and Orthodox monasticism. But before they became saints, they sat at the feet of Macrina.

At twelve years old, Macrina vowed herself to celibacy after the early death of her fiancé, choosing instead a life of prayer, humility, and service. She supported and cared for her mother, St. Emmelia, and later helped transform their family estate into a monastic community for women. Her gentle authority, deep theological wisdom, and unwavering faith earned her the respect and admiration of her brothers, especially Basil and Gregory, who credited her as a spiritual mother and guide.

Even St. Peter, the youngest of her siblings and later bishop of Sebaste, was raised and taught by Macrina after their father’s death. Her instruction and example nurtured his calling and shaped his character.
