John Henry Cardinal Newman 
Fifteen Sermons Preached before the University of Oxford Between A.D. 1826 and 1843 [PDF ebook] 

These remarkable sermons by John Henry Newman (1801-1890) were first published at Oxford in 1843, two years before he was received into the Roman Catholic Church. Published here in its entirety is the third edition of 1872 for which Newman added an additional sermon, bracketed notes, and, importantly, a comprehensive, condensed Preface. In her introduction, noted Newman scholar Mary Katherine Tillman considers the volume as an integral whole, showing how all of the sermons systematically relate to the central theme of the faith-reason relationship.
