Her best friend, Duchess Katherine Brandon, was very involved in reform, and Henry himself left Parr in the care of one of the country's most prominent reformers, Thomas Cranmer, when he became regent. As Mueller discusses in his text, the first written evidence of Parr's reform can be found in a letter from Protestant writer and educator Nicholas Udall, in which he addressed Parr's "scholarly diligence in acquiring knowledge...of the Holy Scriptures." . Udall's own words were not the only indication of Parr's reform. It was the fact that he commissioned Udall to write the English translation of the work that is introducing this letter, rather than choosing someone more inclined to Henry VIII's idea of ​​religion. Since this letter was written after the first publication of Parr Psalms or Prayers (a translation of another text), it can be assumed that Parr's personal reform could have occurred earlier. Regardless of how or when Parr made the decision to reform, she reformed and the decision to do so impacted her life.
