Ecclésiæ sanctæ lumen
divínæ legis amátor
deprecáre pro nobis Fílium Dei.
At Cologne, St. Albert surnamed the Great, at One time Bishop of Ratisbon, and confessor, of the Order of Preachers. Radiant by the holiness of his life, by his zeal for the salvation of souls, and by his surpassing doctrine, he enlightened the Church. Pope Pius XI declared him to be a Doctor of the Universal Church (and Pius XII constituted him patron before God of students of the natural sciences). A totum duplex feast of the first class.
On being admitted amongst the brethren, he gave himself entirely to God, and was outstanding for religious observance and piety. He was inflamed with a filial and most tender devotion towards the blessed Virgin Mary. Having made profession in an apostolic order, he so ordered his whole life that he might, through study founded on prayer, prepare himself to preach the word of God and work for the salvation of souls.
Pius XI set a crown on the sacred honours which, with the permission of the Roman Pontiffs, had been paid to Albert in many dioceses and in the Order of Preachers. He willingly acceded to the request of the Sacred Congregation of Rites and extended the feast of Saint Albert to the whole church, with the added title of Doctor. Finally Pope Pius XII declared Saint Albert the great the heavenly patron before God of those who studied the natural sciences.
