According to the Orthodox Christians all other Christians are Heretics. This means that they consider them to be nonbelievers, or that they do not believe in the faith in the right way. It's also interesting in the Orthodox Christians that in the biggest part of the believers the Bible doesn't play a big part in their beliefs and very small percentage have actually read it, instead it is more like cultural, traditional trait that they stick to it, and in most ways better then the other large fractions of Christianity indeed.
