Ranked by relevance and common usage.
Keep "heretical" when the sentence already sounds natural, when a synonym would add unintended emphasis, or when readers need the most familiar wording. A synonym should clarify or sharpen the message, not simply make the sentence look more varied.
If two options seem close, choose the one that best matches the audience and purpose of the sentence.
Choose a synonym only if it keeps the core idea of "heretical" intact in the sentence you are editing.
Check whether the replacement sounds more formal, casual, emotional, technical, or forceful than the original word.
Read the full sentence after the swap. Keep the synonym only when the sentence becomes clearer or more precise.
Review note: Synonym lists are ranked with lexical data and reviewed for practical writing value. Use the comparison notes, sentence evidence, and source labels together; a high-ranking synonym can still be wrong when the audience, register, or grammar changes.
After choosing a replacement for "heretical", read the sentence once for meaning and once for rhythm. The best synonym should feel natural in the full sentence, not only accurate in a word list.
If the synonym makes the sentence slower, vaguer, or more dramatic than intended, keep "heretical" or choose a simpler alternative from the closest-match group.

At least as Auxentius reports him in the covering letter which precedes Ulfila’s confession, he is as vehement in his opposition to what he sees as heretical alternatives to his own form of belief as most other participants in the controversies of the time. Heretics are not Christians but antichrists. Homoousians, Homoiousians, and Macedonians are all included in this blanket condemnation.
