“His most elaborate and systematic biography ... is not merely a book to be reckoned with; it is one with which we cannot dispense, if only for its minute examination of Luther’s theological writings.”—The AthenÆum.

“There is no room for any sort of question as to the welcome ready among English-speaking Roman Catholics for this admirably made translation of the first volume of the German monograph by Professor Grisar on the protagonist of the Reformation in Europe.... The book is so studiously scientific, so careful to base its teaching upon documents, and so determined to eschew controversies that are only theological, that it cannot but deeply interest Protestant readers.”—The Scotsman.

“Father Grisar has gained a high reputation in this country through the translation of his monumental work on the History of Rome and the Popes in the Middle Ages, and this first instalment of his life of Luther bears fresh witness to his unwearied industry, wide learning, and scrupulous anxiety to be impartial in his judgments as well as absolutely accurate in matters of fact.”—Glasgow Herald.

“It is impossible to understand the Reformation without understanding the life and character of the great German. The man and the work are so indissolubly united that we cannot have right judgments about either without considering the other. It is one of Father Grisar’s many merits that he does not forget for a single moment the fundamental importance of this connection. The man and his work come before us in these illuminating pages, not as more or less harmonious elements, but as a unity, and we cannot analyse either without constant reference to the other.”—Irish Times.

“Professor Grisar is hard on Luther. Perhaps no Roman Catholic can help it. But it is significant that he is hard on the anti-Lutherans also.... He shows us, indeed, though not deliberately, that some reformation of religion was both imperative and inevitable.... But he is far from being overwhelmed with prejudice. He really investigates, uses good authorities, and gives reasons for his judgments.”—The Expository Times.

“This Life of Luther is bound to become standard ... a model of every literary, critical, and scholarly virtue.”—The Month.

“The most important book on Luther that has appeared since Denifle’s epoch-making ‘Luther und Luthertum.’ ... It is an ordered biography, ... and is therefore very probably destined to a wider general usefulness as a Catholic authority.”—The Irish Rosary.
