Are You a Heretic?
Every Christian is — according to someone. Take the quiz to find out which councils would condemn you.
If you've ever wondered "Am I a heretic?" — the answer might surprise you. The question isn't whether you hold views some council condemned. It's how many councils, and which ones. The truth has nothing to fear from honest questions.
Every Christian Is a Heretic According to Someone
This heresy quiz doesn't test whether you're orthodox — it reveals that "orthodox" is a moving target. Over 2,000 years, church councils have questioned virtually every position a thoughtful Christian might hold. Trinitarians were heretics in the 4th century. Protestants are still under anathema from Trent. Catholics are heretics according to the Synod of Dort. This Christian theology quiz maps your beliefs against the real rulings of real councils — and shows you which ones would have condemned you.
Is That Belief Heretical?
It depends who you ask — and when you ask them.
Is universalism a heresy?
The Second Council of Constantinople (553 AD) condemned it. But Origen taught it, Gregory of Nyssa defended it, and it's making a serious comeback in modern theology. The early church was far less settled on this than you'd think. Explore universalism →
Is Arianism really a heresy?
Nicaea (325 AD) condemned it — but for the next 40 years, anti-Nicene theology was the official position of the Roman Empire. Hundreds of bishops rejected the Nicene formula. The "obvious" answer wasn't obvious at all. Explore Arianism →
Is the doctrine of the Trinity heretical?
It was, officially, for twenty years. From 341 to 381 AD, the Nicene Trinitarian formula was condemned across the Roman Empire. The belief most Christians treat as non-negotiable was once the heretical position. Explore Nicene Trinitarianism →
Is infant baptism biblical?
Catholics and Reformers say yes. Baptists and Anabaptists say no — and people were executed for that view. The Anabaptists were condemned at Augsburg (1530), but believer's baptism is now the majority practice worldwide. Explore the baptism debate →
Is believing in predestination heretical?
The opposite view is. The Council of Orange (529 AD) condemned the idea that humans can choose God without grace — that's Pelagianism. But strong predestination was condemned at Arles (473 AD). Every position on the spectrum has been condemned by someone. Explore the grace debate →
Is sola scriptura heretical?
The Council of Trent (1545) condemned it. But it's the foundation of Protestantism — and half the world's Christians hold to it in some form. Meanwhile, Catholics consider the Protestant rejection of tradition heretical. Both sides have councils backing them up. Explore sola scriptura →
Is speaking in tongues still real?
Cessationists say the miraculous gifts stopped with the apostles. Continuationists — now the fastest-growing segment of global Christianity — say they didn't. The early church condemned Montanism for claiming new prophecy, but never ruled the gifts had ceased. Explore cessationism →

Unity in Christ: Why Your Heresy Doesn't Define You
Every Christian is someone else's heretic. But the New Testament cares more about unity, love, and humility than getting every doctrine exactly right. Here's why your label doesn't define you.
The 20 Years When 'Orthodox' Was 'Heretical'
For two decades, the belief now considered the bedrock of Christian orthodoxy was officially condemned across the Roman Empire. If the 'right' answer was always so obvious, how did that happen?
The Council of Rimini: When 400 Bishops Were Bullied Into Heresy
In 359 AD, over 400 bishops arrived at Rimini ready to affirm the Nicene Creed. They left having signed its condemnation. Here's how imperial coercion overrode theological conviction.
