In February 1843, Newman published, as an advertisement in the "Oxford Conservative Journal", an anonymous but otherwise formal retractation of all the hard things he had said against Roman Catholicism. Lockhart became the first in the group to convert formally to Catholicism. Newman preached his last Anglican sermon at Littlemore, the valedictory "The parting of friends" on 25 September, and resigned the living of St Mary's, although he did not leave Littlemore for two more years, until his own formal reception into the Catholic Church.
