More positively, the prominent evangelical theologian J. I. Packer was converted to evangelical Christianity at an OICCU meeting in the 1940s, during his first week at the university. While a student member he was not regarded as doctrinally sound enough to join the Executive Committee. However, he was appointed Librarian, taking a particular interest in OICCU's selection of out-of-print Puritan books. In the following decade Packer, along with Martyn Lloyd-Jones, led a revival of Puritan studies amongst British pastors. He returned to Oxford in 2004 as the guest of honour at the 125th Anniversary celebrations.
