Carlile resigned his curacy to devote his time to slum missions. His goal was to use the working person to help fellow workers, but to do so within the structure of the Church of England. Such work had already begun in a few other areas of England. Carlile wanted to co-ordinate all their efforts, so that trained evangelists could be sent to any parish where they were needed. During this time, he visited
the Salvation Army, where he received a "Soldier's Pass" which admitted him to private gatherings. He showed this on a train to his friend, F. S. Webster, the future rector of
All Souls Church, Langham Place. Webster recalls, "I remember Mr Carlile explained that it was an Army and not a Church, that people could be banded together for purposes of evangelisation and soul-winning." Carlile began a "Church Salvation Army" in Kensington while Webster began one in Oxford.
Bramwell Booth remembered Webster as "more than once walking in our processions, singing the praises of God though plastered with mud from head to foot." It took time for the idea to catch hold, but in 1882 the
Church Army was born. When asked, "Why 'Army?' ", Carlile's answer was that the evangelists intended to make war against sin and the devil. Also it was a time of wars - the
Franco-German war and the
First Boer War were not long over. It was a time of Army consciousness and discipline from above. The first Church Army campaign was held in
Belfast in 1883. In his position as head of the Church Army, he remained authoritative, but he always recognised the higher authority of the Church of England. No work was carried out in any parish without the approval of the incumbent, nor in any prison or public institution unless the evangelists were invited by the chaplain. Carlile met resistance in the early years but he persisted in trying to acquaint clerics and public officials in major cities with Church Army's aims, ideas and methods. In 1885, the Upper House of the
Convocation of Canterbury passed a resolution of approval. With increasing support from a few bishops, the Army gradually gained the respect of the church. By 1925, the Church Army grew to become the largest home mission society in the Church of England and he was appointed a
Member of the Order of the Companions of Honour (CH) in the
1926 New Year Honours. Carlile ministered at
St Mary-at-Hill in the
City of London, in the late 19th/ early 20th century. In his later years Carlile shared a house with his sister Marie Louise Carlile in Woking. He continued to take part in the administration of the Church army until his death in
Woking on 26 September 1942. His ashes were interred at the foot of his memorial in St Paul's Cathedral. ==Family==
