At this date Newman became editor of the British Critic, and he also gave courses of lectures in a side-chapel of St Mary's in defence of the via media of the Anglican Church as between Romanism and popular Protestantism.
He soon became prominent; first by his contributions to its organ the Messenger; then by The Anxious Bench - A Tract for the Times (1843), attacking the vicious excesses of revivalistic methods; and by his defence of the inauguration address, The Principle of Protestantism, delivered by his colleague Philip Schaff, which aroused a storm of protest by its suggestion that Pauline Protestantism was not the last word in the development of the church but that a Johannean Christianity was to be its outgrowth, and by its recognition of Petrine Romanism as a stage in ecclesiastical development.
In all their negotiations with Ormonde and Glamorgan, Henrietta Maria and the earl of Bristol, the pope and Rinuccini stood out for an arrangement which would have destroyed the royal supremacy and established Romanism in Ireland, leaving to the Anglicans bare toleration, and to the Presbyterians not even that.
Jerome Hermes Bolsec, a Carmelite friar, having renounced Romanism, had fled from France to Veigy, a village near Geneva, where he practised as a physician.
Nevin (q.v.), by its Neander-like view that Romanism and Protestantism were only stages in the divinely appointed development of the Christian Church, aroused fierce opposition in the Reformed Church and Schaff was characterized as "Puseyistic" and "semi-papistical"; in 1845 he was tried for heresy and found not guilty by the Synod.
