Maurice thought it was wrong that different types of Christians should dislike each other so in his most important book, The Kingdom of Christ (1838) he argued that each denomination held their own particular part of the truth, and should be listened to and treated as equals. He also argued that it was important for Christians to be involved in politics and to try to improve the social conditions of those around them. He was strongly in favour of improving education for the poor and for those who did not agree with the Church of England and so were not allowed to attend Universities.
Maurice was made a professor of religion at King’s college London in 1840. People in England had been shocked by the French revolution and were afraid that the poor in England might rebel. Maurice formed the Christian Socialist movement with his friends the writers Charles Kingsley and Thomas Hughes. It was designed to be an alternative to the humanistic socialism of the day, and to help the poor without causing a revolution.
However people thought that this sounded very dangerous, and Maurice was forced to resign his professorship in 1853. He helped start the London Working Man’s College in 1854 and in 1866 he was appointed Professor of Moral Philosophy at Cambridge University.
