Jerome Gratian by Carlos Ros (St Paul’s, £19.99). Those who have read the letters of St Teresa of Avila will know of her correspondence with her dear friend and confessor Fr Jerome Gratian. Indeed, he was closer to her than her famous contemporary St John of the Cross. This new and fascinating biography of Gratian, translated by John McGowan OCD, reveals the human side of sanctity (and of Teresa herself). Once reprimanded by Gratian for being too effusive towards him, Teresa replied characteristically: “Do you not know that no matter how perfect a soul may be it still needs an outlet?”
