Elizabeth of the Trinity was a French Discalced Carmelite nun and mystic who lived from 1880 to 1906. Born Élisabeth Catez in Bourges, she entered the monastery in Dijon in 1901, choosing religious life over marriage. Despite experiencing periods of spiritual doubt, she remained dedicated to the Carmelite charism and developed a profound devotion to the Holy Trinity. A gifted pianist and prolific spiritual writer, she died at the young age of 26 due to Addison's disease, accepting her suffering as a divine gift.
