In writing Whom God Hath Not Joined Claire McAuley has blazed a ""little traveled trail"" as she explores the problems of couples married legally, according to civil law, but, because one had been divorced, living in adultery in the eyes of the Church, now wishing to become reconciled to their religion. This provocative book points out that they must accept separation or a brother-sister relationship as the only possible solution. The McAuleys chose the latter, and the author never minimizes the difficulties inherent in an ""almost impossible life"". Mrs. McAuley claims that the taking of the ""Frater-Sorer"" vows (rarely permitted by the Church) has made her and her husband feel ""alive for the first time in years"" by bringing them back to the Sacraments. A retreat master prevailed on Mrs. McAuley to describe these moving experiences with their very special problems for a young, attractive, in-love couple in order to help others in similar circumstances. Maisie Ward, famous English author, writes an appealing introduction. This is a book in a class by itself. It is a tribute to the author's lively humor that readers admire, far more than pity, the McAuleys.
