There are many Baptists these days who seem to love the Reformers, even to the point of claiming a kind of kinship with them. I am afraid that many of them know neither the history of their own doctrines nor the practice of those Protestant Reformers.
On this day in 1525 the following proclamation was made against the Anabaptists – those who “re-baptized” the believers who had been sprinkled as babies. They immersed, because they could see only believer’s baptism in the Bible. In Zurich, the home of Zwingli, one of the more “moderate” of the reformers, the following became law: “We ordain, and it is our will, that henceforth all men, women, young men, and maidens, abstain from re-baptism, and from this time practice it no more; and that they bring their children to be baptized [sprinkled by us]. For whosoever shall act contrary to this public order, shall, as often as it occurs, be punished by a fine of a mark of silver; and if any shall be altogether rebellious, they shall be dealt with severely; for we will protect the obedient [to us], and punish the disobedient according to his desserts without further forgiveness.” Five years later the edict was amended to say, “We will punish the Anabaptists with death together with those who sanction or follow them.”
