Sir Thomas Walker Arnold,
The Preaching of Islam: A History of the Propagation of the Muslim Faith
“ The religion of the people had degenerated into a scrupulous observance of outward forms, and the intense fervour of their devotion found an outlet in the worship of the Virgin and the saints, of pictures and relics. There were many who turned from a Church whose spiritual life had sunk so low, and weary of interminable discussions on such subtle points of doctrine as the Double Procession of the Holy Spirit, and such trivialities as the use of leavened and unleavened bread in the Blessed Sacrament, gladly accepted the clear and intelligible theistic teaching of Islam. ”
