Anabaptist
Oversimplified
- A 16th-century Radical Reformation movement that rejected infant Baptism and re-baptized adult believers ("ana-baptist" = "re-baptizer").
- Martin Luther cracked the door open; the Anabaptists kicked it off the hinges.
Summary
The Anabaptists broke from the reformer Huldrych Zwingli because they judged his reform too timid — it had not gone far enough. Their defining conviction was believers' baptism: only those old enough to make a conscious profession of faith should be baptized. Their beliefs were first set down in the Schleitheim Confession (1527), whose author, Michael Sattler, was executed soon after writing it. They were persecuted savagely by Catholic and Protestant authorities alike.[^2]
The core claim: believers' baptism
"Baptism requires a conscious decision, so an infant cannot be baptized."
The assumption underneath is that baptism is essentially a testimony we give — a public sign of a decision already made — rather than a gift God gives. Orthodoxy answers from soteriology, not sentiment: baptism is the first step on the road to Theosis, the indwelling of the Holy Spirit and the planting of divine life, not merely a badge of conversion. Once baptism is a divine act rather than a human profession, the age of the recipient stops being the decisive question — just as an eight-day-old received the covenant sign of circumcision. The full answer, with the Fathers, lives in Baptism (§ Infant Baptism): households and circumcision, and St. John Chrysostom on what an infant genuinely needs — not forgiveness of personal sins it hasn't committed, but immortality and the Spirit.[^1]
The Radical Reformation
The Anabaptists were the left wing of the Reformation, refusing the half-measures of the "magisterial" reformers who kept the Church wedded to the civil state. They rejected infant baptism, oaths, and often the sword, and sought a "gathered church" of the visibly committed. Beliefs varied widely then and still do; there was no single Anabaptist authority — a feature that itself flows from the Sola Scriptura and private-judgment instinct.
Martyrdom on every side
The Anabaptists found no safe harbor on either bank of the Catholic–Protestant divide.
- Catholic response. Rebaptism had been a capital crime since the Justinian code; authorities executed Anabaptists across the Empire, often by drowning — a punishment chosen with grim irony.
- Protestant response. Luther, Zwingli, and Calvin all endorsed civil punishment to varying degrees. Zwingli's Zurich drowned Felix Manz in 1527 — among the first Protestant executions of a Protestant dissenter.
- In fairness. The Münster Rebellion of 1534 — an armed Anabaptist "New Jerusalem" that instituted polygamy — genuinely alarmed all of Europe and made it hard, in the moment, to tell peaceful Anabaptists from revolutionary ones.
An Orthodox assessment
The Anabaptist instinct was half right and half tragic. They rightly refused a merely nominal, state-managed Christianity and insisted baptism must mean something. But by anchoring baptism in the believer's decision rather than God's action, they cut themselves off from the very sacramental life that makes discipleship possible — trading the Church's gift for the individual's testimony.
