 Both stress the importance of personal devotion and a life of perfection, both incorporate the catechetical lists, and both are heavily Biblical in content.The emphasis on lay piety and Biblical translation together have caused some to doubt the orthodoxy of both books; indeed, Pore Caitif, Book to a Mother, and Life of Soul have all aroused suspicions of sympathies with the Lollard movement.After the 1407 prohibition by Bishop Arundel of lay ownership of the Scriptures in English, possession of either Life of Soul or Book to a Mother could have been grounds for suspicion or even prosecution.
