a stir when he announced at a meeting of the Theosophical Society in London that he believed in reincarnation, and that he believed that when Jesus returned for the Second Coming he would be reincarnated. On 5 September 1911 Campbell met `Abdu'l-Bahá, the eldest son and successor of Bahá'u'lláh, the founder of the Baháʼí Faith, and invited him to give a public address in the City Temple a few days later. In October 1911, accompanied by his wife and daughter, Hilda May (1891–1935), he embarked on a three-month preaching tour of the United States. Return to Anglicanism In the summer of 1915, after a tour of the trenches during World War I, Campbell underwent a deep personal crisis, seeing a need for greater Christian unity, and for himself a return to the Church of England. This crisis, which led him to turn from being a liberal Protestant to being a liberal Catholic, came largely from his earlier researches into Biblical criticism and the historical Jesus, his conclusions leading him to the opinion that the Jesus of liberal Protestantism did not exist, and that the historical Jesus was much closer to that taught in Catholic doctrine. He wrote: "It was the Christ of the Catholic Church that stood forth from the newer criticism of the gospel sources, not the Christ of liberal Protestantism. This was thrust forcibly upon my attention. The alternatives were obvious : Either Jesus was what the Catholic Church said He was or He did not exist; either He was the Man from heaven, a complete break with the natural order of things, the representative of a transcendental order, supernatural, super-rational super-everything, or He was nothing. This was scarcely the Christ of Protestantism at all, whether liberal or conservative." He considered rewriting his book, The New Theology, keeping to the same sequence of subjects, but correcting all the points in which it was at variance with Catholic doctrine. Eventually, he felt that the book's title made such a move impossible, so instead, in March 1915, he decided to withdraw the book and purchased the publishing rights to prevent its possible re-issue. In October 1915 Campbell preached his last sermon at the City Temple and resigned from the Congregational church; a few days later he was received back into the Church of England by Bishop Gore at Cuddesdon. In October 1916 he was ordained as an Anglican priest, and
