For many years Denison represented the extreme High Tory party not only in politics but in the church, regarding all progressive movements in education or theology as abomination, and vehemently repudiating the higher criticism from the days of Essays and Reviews (1860) to those of Lux Mundi (1890).[4]
On 7 August and 6 November 1853, he preached two sermons in Wells Cathedral on the real presence of Christ in the Eucharist, taking a position similar to that for which Edward Bouverie Pusey had been suspended ten years before.[3] He resigned his position as examining chaplain to the Bishop of Bath and Wells owing to his pronounced eucharistic views. A suit on the complaint of a neighbouring clergyman ensued and after various complications, Denison was condemned by the archbishop's court at Bath (1856).[4] The judgment did not pass unchallenged, and that autumn a protest was issued arguing that Denison's teaching conformed with the best Anglican authorities. The protest was signed by fifteen of the most prominent Anglo-Catholics of the time, including Pusey, John Keble, and J. M. Neale.[3]
The case was significant for the various writings on the Eucharist that followed. In 1857, before the Court of Appeals had rendered its decision, John Keble wrote one of his more important works, his treatise on eucharistic adoration, in support of Denison.[6] Pusey published his Doctrine of the Real Presence in the summer of 1857.[7]
The result was to make Denison a keen champion of the ritualistic school, although he, himself, never wore vestments. He edited The Church and State Review (1862–1865). Secularstate education and the conscience clause were anathema to him. Until the end of his life, he remained a protagonist in theological controversy and a keen fighter against latitudinarianism and liberalism; but the sharpest religious or political differences never broke his personal friendships and his Christian charity. Among other things for which he will be remembered was his origination of harvest festivals.[4]
