An anathema is an expulsion from the Church.
- Now suppose that some member not only refuses to abide by the rules but also holds many views completely opposed to those of the society and even rises up against its very goal. He not only does not himself observe temperance but even reviles temperance itself and disseminates notions which might tempt others and deflect them from temperance. What does the society ordinarily do with such people? First it admonishes them, and then it expels them. There you have an anathema! — St. Theophan the Recluse
