Image: Chalice of St John of the Cross

"You should strive in your prayer for a pure conscience, a will that is wholly with God, and a mind truly set upon Him."

A chalice used by St John of the Cross, and by Pope John Paul II, thus making it a relic used by two holy men! This chalice is in the museum of the convent of the Incarnation in Ávila. Today, 14 December, is the feast of St John of the Cross. Monasterio de la Encarnación, Avila, Spain.
