Phillips was the great-nephew of William Joyner, a prominent Catholic convert, whose sister, Mary, married an attorney, Thomas Phillips; the couple had a daughter, and a son, Thomas, who converted to Roman Catholicism. He, in turn, married Elizabeth Crosse, daughter of Johnshall Crosse of Bledlow, and they had nine children (eight sons and one daughter), including Thomas Phillips, the Jesuit priest and biographer.[1][2][3]
Phillips's early schooling was Protestant, after which he was sent to the College of St Omer. When he had completed his course of rhetoric he entered the novitiate of the Society of Jesus at Watten on 7 September 1726, and made the simple vows of the Society on 8 September 1728. He was then moved to the English College, Liège for his three-year course of philosophy.[citation needed]
Soon after Phillip's admission to holy orders his father died, leaving him independently wealthy. He travelled through the Netherlands, Germany, France, and Italy, visiting universities, and forming friendships. During the third year of his philosophical course, on 17 July 1731, he made a voluntary renunciation of his property to the college at Liège and the provincial, the Rev John Turberville. In the second year of his course of theology he sought permission to conduct a course of humanities at St Omer, against the requirement of the Society to accept assignments, and he was turned down. On 4 July 1733 he withdrew from the Society.[1]
Phillips's major work was The History of the Life of Cardinal Pole (1764).[5] His object in it was to give an account of the Council of Trent from a Roman Catholic point of view.[1]
Other responses came from Timothy Neve, John Jortin, Edward Stone and Richard Tillard. William Cole's unpublished Observations on answers to Phillips's book, and correspondence with the author, went to the British Museum. Phillips himself appended An Answer to the principal Objections to his Study of Sacred Literature (1765).[1][7] He responded to the 1766 Animadversions by Neve, who had defended the characters of Protestant reformers, in later editions of the History.[8]
