An article by Wiseman on the Donatist schism, appearing in the "Dublin Review" in July 1839, made an impression in Oxford, Newman and others seeing the analogy between Donatists and Anglicans. Wiseman, preaching at the opening of St Mary's Church, Derby, in the same year, anticipated Newman's argument on religious development, published six years later. In 1840, he was consecrated bishop, and was sent to England as coadjutor to Bishop Thomas Walsh, vicar-apostolic of the Central district, and was also appointed president of Oscott College near Birmingham.
