with Queen Catherine any further. During this time, Catherine began having altercations with her brother-in-law, Edward Seymour, 1st Duke of Somerset. Like Thomas, Edward was the king's uncle, and also was the Lord Protector. A rivalry developed between Catherine and his wife, her own former lady-in-waiting, Anne Seymour, Duchess of Somerset, which became particularly acute over the matter of Catherine's jewels. The Duchess argued that Catherine, as queen dowager, was no longer entitled to wear the jewels belonging to the wife of the king. Instead she, as the wife of the protector, should be the one to wear them. The whole ordeal left her relationship with Catherine permanently damaged; the relationship between the two Seymour brothers also worsened as a result, since Thomas saw the whole dispute as a personal attack by his brother on his social standing. In November 1547, Catherine published her third book, The Lamentation of a Sinner. The book promoted the Protestant concept of justification by faith alone, which the Catholic Church deemed to be heresy. It was sponsored by Katherine Brandon, the Duchess of Suffolk, and by William Parr (Catherine's brother), and William Cecil, Elizabeth I's future chief minister, wrote the preface. It is unlikely that she developed these views in the short time between Henry's death and the publication of the book. In 1544 or 1545, Parr had started to organise an English translation of Erasmus's Paraphrases Upon the New Testament, and the massive volume was finally printed in January 1548. Parr had enlisted Nicholas Udall, Thomas Keyes and Mary Tudor to translate different sections and she may have produced the paraphrase of Matthew. In July 1547 the Edwardian state ordered every parish to obtain a copy and many generations of literate parishioners would have encountered lengthy dedications praising Parr's learning, her commitment to the vernacular Bible, and her role in the English reformation. Parr owned many books and she participated in the cultural practice of writing in her books and signing books that belonged to others. At the age of 35, Catherine became pregnant. This pregnancy was a surprise, as Catherine had not conceived during her first three marriages. During this time, Seymour began to take an interest in Lady Elizabeth. Seymour had reputedly plotted to marry her before marrying Catherine, and it was reported later that Catherine discovered the two in an embrace. On a few occasions before the situation risked getting
