Learned and filled with holiness, he not only organized the constitutions, and established the Salve Regina after compline but was instrumental guiding the work of others to establish the Dominican Liturgy. Though master-general of the order, Bl. Jordan's humility prevented him from attributing himself as a director of any human authority. He was not and did not wish to be anything but a docile instrument of grace. As a director of conscience in his breadth and delicacy, Jordan had the Catholic sense of the omnipotent and infinite freedom of God and of the supernatural freedom of souls in relation to God. Like Dominic, he had the faith which moves mountains, and also he had hope of great assistance, which was never to fail him, especially and above all that of the Roman Church. Marguerite Aaron captures the man and his times in this excellent biography, which not only makes use of the ample historical documentation but also utilizes them to enter intimately into his personality, a rare thing with the famous men of his era. Tracing his time from the University of Paris to his death, Aron's biography is a first rate history, readable, well sourced and well-written. This is the only source in English to learn about the man who picked up and carried St. Dominic's torch!
