This book was first published in Dutch and met with immediate and extensive acclaim. It covers Newman's young life as an Anglican, the doubts he faced in light of his historical studies, his conversion to Catholicism, the trials he faced as a result of his conversion, and his remarkable growth in holiness and the interior life.
"It took me, all in all, fifteen months to examine the 430 files of letters in the Archivium and the formidable collection of papers, journals and memoranda in the cupboards of the Cardinal's room... Studying the forty-five volumes of Newman's works which had up to then been published also required much time. While I read and copied out what threw light on his inner life, the outlines of Newman's soul gradually became clear to me: the following pages are the result of this labor of love."
