Yeshua (”Jesus”, if you will) was pretty much “Anathematized” by the Jewish Sanhedrin or dominant religious institution of his time, wasn’t he?
Is it a sin to be anathema to an apostate religious institution (”Church”)?
...Or is it a sacred obligation?
Or an anachronism? These “anathemas” from 500 or 1500 years ago aren’t on many people’s minds nowadays, even if we confine the discussion to believers and clergy.
