This tract against Romish Anglicanism appeared in the August 1865 issue of The Sword and the Trowel. The Tractarian Movement, begun in the 1820s and led by John Henry Newman, had started a drift toward Catholicism within the Church of England. Newman himself converted to Catholicism in 1845, and in the intervening 20 years, more than 250 Anglican clergy followed him. This tract was part of Spurgeon's response to that trend.
