Richard Whately (1787-1863) is an intriguing figure in John Henry Newman’s development. Through his mentoring and academic support, he taught the gifted young Newman to think for himself. But intellectual independence came at a price. After a close relationship in the mid-1820s, Newman began to steer a course of his own. In the tumultuous early 1830s, their friendship foundered, as they clashed over key theological issues: the authority of the church, the doctrine of the Trinity, the nature of revelation, and the reasonableness of religious belief. Newman had come to think that Whately's theology endangered orthodox Christianity. This conviction shaped his later opposition to other Oriel Noetics, who thought like Whately. Despite their conflicts, Newman drew on Whately's work in logic and rhetoric to formulate his own theory of the relation between faith and reason.
