Round glass-fronted yellow-metal reliquary theca housing the first-class ex ossibus (of the bone) relic of Saint John of the Cross. The relic is affixed to a red silk ground and identified in Latin on a typeset cedula label as S. Joannis a Cr. Doct. (Saint John of the Cross, Doctor [of the Church]). On the back, under the 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 the original matching authentics document issued and signed in 1991 by the Postulator General of the Order responsible for the cause of beatification and canonization.
Saint John of the Cross, O.C.D. (†1591) was a mystic, poet, and Carmelite friar. After joining the Carmelites in 1563, he collaborated with Saint Teresa of Ávila to reform the order, emphasizing austerity and contemplative prayer. His efforts led to imprisonment in 1577, during which he wrote profound mystical poetry, including The Dark Night of the Soul. His writings, blending theology and spirituality, explore the soul’s union with God. Canonized in 1726 and declared a Doctor of the Church in 1926, his feast day is December 14.
