"Few of our own living authors have given us a work at once so profound, so apt and so persuasive as this of the great French Jesuit, Certainly, few could have written the book on the basis of such a rich knowledge of the Christian tradition. . . . De Lubac's thought has the originality which springs from the contact with a great tradition of a brilliant, deep and charitable mind. And it has a contemporaneity that bears witness to a profound, all-embracing, human concern. This book could not have been written in any age before the present one. May it help many of us to see the way, by personal appropriation of the religion of charity, to contribute to the foundations of another and a better age to succeed our own."
