Baptists

Baptists, a denomination of Christians, sometimes called Anabaptists to distinguish them from Pædobaptists, who, however they may and do differ on other matters, insist that the rite of initiation is duly administered only by immersion, and to those who are of age to make an intelligent profession of faith; they are a numerous body, particularly in America, and more so in England than in Scotland, and have included in their membership a number of eminent men.
