Sanctified Life

Thuringia, Holy Roman Empire
Also Known As
Patronage
"O Sacred Heart of Jesus, fountain of eternal life, Your Heart is a glowing furnace of Love. You are my refuge and my sanctuary."
Gertrude the Great entered the Benedictine Monastery of Helfta at age five and never left — yet from that cloister she produced some of the most theologically precise mystical writing of medieval Germany. At twenty-five, a vision of Christ shattered her pride in learning and turned her entirely toward the Sacred Heart, making her its first great systematic theologian and the only woman saint to bear the title 'the Great.'

On January 27, 1281, a vision of Christ taking her hand shattered her pride in learning and turned her entirely toward prayer and mystical theology.
Legacy
Her masterwork, The Herald of Divine Love, became a cornerstone of Sacred Heart devotion; Pope Benedict XIV made her the only woman saint to bear 'the Great.'

Words & Wisdom
The Herald of Divine Love
Gertrude's masterwork — partly written by her own hand, partly dictated to sister nuns — describing her mystical encounters with Christ's Sacred Heart in vivid, theologically precise language that helped establish Sacred Heart devotion as a pillar of Catholic piety.
Eternal Father, I offer Thee the Most Precious Blood of Thy Divine Son, Jesus, in union with the masses said throughout the world today, for all the holy souls in purgatory, for sinners everywhere, for sinners in the universal church, those in my own home and within my family. Amen.
O God, who prepared a dwelling place for yourself in the heart of the virgin Gertrude, graciously bring light to our hearts through her merits and example, so that we may joyfully seek you, the fount of all good, and in finding you, may find our rest. Through Christ our Lord. Amen.

Connections in the communion of saints
Bernard of Clairvaux
Bernard's Sermons on the Song of Songs and his theology of love were central to the curriculum at Helfta — his bridal mysticism provided the theological grammar Gertrude would develop into her own nuptial spirituality.
Bonaventure
Bonaventure and Gertrude were near-contemporaries charting the same mystical terrain — both mapping the soul's ascent to God through affective union — though within different orders and idioms.
Teresa of Ávila
Teresa of Ávila drew on the tradition of women's mystical theology that Gertrude helped establish; both wrote with unusual theological authority about the interior life and the experience of divine union.
