Early Life and Vocation
Teresa Sanchez de Cepeda y Ahumada was born in Avila into a large, well-off family. Her paternal grandfather was a converso, a Jewish convert to Christianity, a fact that has drawn much attention from modern historians. As a child she read lives of the saints and, famously, tried with her brother to run away to seek martyrdom. Her mother died when she was a young teenager.
In 1535 she entered the Carmelite Convent of the Incarnation in Avila. Soon afterward she suffered a long and severe illness. For many years she lived a conventional religious life, practicing prayer irregularly and enjoying conversation with visitors in the convent parlor. She later described this period as one of spiritual lukewarmness.
Conversion and Mystical Experiences
Around 1554, when she was about forty, Teresa experienced a decisive conversion while praying before an image of the wounded Christ. In the following years she reported intellectual visions, locutions (inner words) and raptures. The best-known is the transverberation, in which she described an angel piercing her heart with a golden spear tipped with fire, leaving her aflame with love of God. Gian Lorenzo Bernini's sculpture The Ecstasy of Saint Teresa in the Cornaro Chapel in Rome depicts this episode.
Because such claims were viewed with suspicion in sixteenth-century Spain, where the Inquisition was watchful of alumbrados ("illuminated ones"), Teresa consulted many confessors, and at their request she wrote an account of her life and prayer. Her Life was examined by the Inquisition but was not condemned.
The Carmelite Reform
Teresa believed that her order needed a stricter, more contemplative life. In 1562 she founded the small convent of St. Joseph in Avila, where the nuns lived in poverty, enclosure and silence and went without shoes or wore simple sandals, from which the name "Discalced" (barefoot) derives. Despite opposition from church and civic authorities, she went on to establish many more houses across Spain, recording her travels in the Book of Foundations.
In 1567 she met the young friar John of the Cross and enlisted him to extend the reform to male Carmelites. The movement faced serious conflict, including John's imprisonment by opponents in 1577, but the Discalced Carmelites were eventually recognized as a separate province and later an independent order.
Teaching on Prayer
Teresa's teaching is practical and vivid. In The Way of Perfection she instructed her nuns in mental prayer, which she described as friendly conversation with God. In her Life she compared the stages of prayer to four ways of watering a garden, from drawing water laboriously from a well to receiving rain from heaven.
The Interior Castle (1577), her most mature work, portrays the soul as a castle made of a single diamond or clear crystal with seven dwelling places ("mansions"). The journey inward passes through self-knowledge and humility to the prayer of quiet, the prayer of union and finally the "spiritual marriage" at the center, where God dwells. Her teachings belong to the broader history of Christian mysticism and are often compared with the negative way of apophatic theology developed by John of the Cross.
Main Writings
- The Life (Libro de la vida): an autobiography written at the request of her confessors, recounting her spiritual development and her teaching on the four degrees of prayer.
- The Way of Perfection: practical instruction for her nuns on community life, humility and prayer, including a commentary on the Lord's Prayer.
- The Interior Castle (Las moradas): her mature synthesis of the spiritual journey through seven dwelling places.
- The Book of Foundations: a lively account of the founding of her convents.
- Letters and poems: several hundred letters survive, along with poems and short spiritual texts.
Her works were first published together in 1588, edited by the Augustinian friar and poet Luis de Leon.
Death and Legacy
Teresa died at Alba de Tormes on the night of 4 October 1582, the very night Spain adopted the Gregorian calendar; the next day was therefore 15 October, which became her feast day. She was beatified in 1614 and canonized in 1622. In 1970 Pope Paul VI proclaimed her a Doctor of the Church, the first woman to receive that title, along with St. Catherine of Siena shortly afterward.
Her writings are admired as masterpieces of Spanish prose and continue to be read by Christians and by readers interested in comparative mysticism, psychology of religion and women's history.
