Round gilt metal reliquary theca housing the first-class ex pulvere corporis (small particles from the body) relics of Saint Teresa of Ávila (of Jesus). The relic is affixed to a red silk ground and identified in Latin on a typeset cedula label as S. Teresiae a Iesu I. Eccl. Doctoris (Saint Teresa of Jesus, Ecclesiastic Doctor of the Church). On the back, under a protective cap, the theca is secured with a seal of red Spanish wax bearing an imprint of a coat of arms of the Discalced Carmelites order. The relic is accompanied by an original matching authentics document issued in 2001 and signed by Fr. Ildefonso Moriones, the Postulator General of the Carmelite Order.
Saint Teresa of Ávila, also called Saint Teresa of Jesus († 1582), was a prominent Spanish mystic, Carmelite nun, author during the Counter-Reformation, and theologian of contemplative life through mental prayer. She was a reformer of the Carmelite Order and is considered to be, along with John of the Cross, a founder of the Discalced Carmelites. She was canonized in 1622 by Pope Gregory XV, and in 1970 was named a Doctor of the Church by Pope Paul VI. She is a Holy Patron of bodily ills; headaches; chess; loss of parents; people in need of grace; people in religious orders; people ridiculed for their piety; sick people; and sickness.
