Revolution of Tenderness and Love

Walter Kasper's book, Pope Francis' Revolution of Tenderness and Love, was published by Paulist Press in 2015 and has some great quotes and depicts insight into the theological and pastoral perspectives of Pope Francis. Kasper also compares and contrasts the present Pope with Benedict and other former Popes. Here is an example:
After explaining how Benedict's "manner of speaking consists in instruction that has been spiritually thought through and lived out" Kasper tells us that "Pope Francis, on the other hand, is defined by kerygmatic theology. In this way he is not a covert Franciscan; he is a Jesuit through and through. In the spirit of the founder of his order, Ignatius of Loyola (1491-1556), he proceeds not from doctrine, but from the concrete situation. Naturally, he does not simply intend to accommodate himself to the situation, rather, as is envisaged in the Spiritual Exercises of Ignatius, he attempts to evaluate the situation according to the rule for discernment of spirits. With the help of such spiritual discernment, he then comes to concrete, practical decisions."
