I was originally under the impression with the books title that the sermons on conversion where going to be centered around the benedictine vow of conversion, that is being daily more converted unto Christ because the author was one of the greatest benedictine reformers. Instead the homilies on conversion are directed at turning from a life of sin to one of repentance and holy living.
The introduction to the sermons is very helpful at understanding where the translations come from and who the intended audience once. St. Bernard went out of his way to preach this sermons in Paris to clerics whom he strongly rebukes during the homilies. St. Bernard lists impurity, ambition, greed and even goes as far as to say "If only those today who are not shepherds would at least show themselves hirelings and not wolves. If only they would not devour [the sheep]." The homilies are a practical call to penance, and are vivid and down to earth when describing how the flesh will rebel against new discipline and repentance.
The sermons on conversion are the smallest part of the book, the larger part of the book is a collection of homilies on Psalm 91, which St. Bernard gave to his own community during the lenten season. There is much that could be said about the depth of these 17 homilies that vary in length and they are appropriate companion to the sermons on conversion. The book also contains a wonderful index and scriptural index which make it handy for a reference.
"Yet not only this but, as I have expressly said, let us glory in tribulation, for in it lies the hope of glory." The homilies of the book illustrate that even at the height of Christendom God still allowed the good and wicked to grow in the same field, and that their was never a time where a person might find their salvation secure even with the greater state and cultural support of the Church. If you are looking for a book that calls the reader to penance with an author of delightful wit and is filled with vivid imagery and citations of scripture you will enjoy this book.
