Pope Clement XII desiring to honor the Mystical Doctor of Carmel, famous for the help he gave to St. Teresa in the reform of her Order and for his mystical writings, in which he taught the science of the saints for the good of souls, introduced his feast in the Calendar. Pius XI (November 24, 1926) proclaimed him a Doctor of the Church.

His life was filled with difficulties and embittered by anxiety, fatigue, persecution and painful illnesses. When Jesus asked him one day what reward he desired for the labors he had sustained, John replied: “Lord, to suffer and to be humiliated for Thee.” He asked God to permit him to die where he would be unknown to all. He passed to a better life on December 14, 1591.
