hmm…

in the Canons themselves I only see the anathematizing of beliefs and not the excommunication of any persons. I am looking at the New Advent site on
this page.
The CE article says: “All the councils, from the Council of Nicæa to that of the Vatican, have worded their dogmatic canons: ‘If any one says . . . let him be anathema’.”
I suppose one could look back to the early Ecumenical Councils (or other primary sources perhaps) to verify what
the article says, that: “…during the first centuries the anathema did not seem to differ from the sentence of excommunication…”
I think Jurgens’ “Faith of the Early Fathers: Vol. 1” may have (at least part) of Nicaea in it, maybe I’ll have a look later.
Here are a couple of Canons from Ephesus I:

I’m no expert but, it seems that they could be interchangeable here as the punishment for clergy in Canons 6 and 7 above seems to be deposition in all cases here but in Canon 6 the laity are to be “excommunicated” whereas in Canon 7 the laity are to be “anathematized” .
More specifically, in Canon 6 the punishment for the clergy is that they “they shall absolutely forfeit their office” while the laity are “excommunicated”, whereas the clergy in Canon 7 are either “deposed” or “removed from his bishopric” or “stricken from the clergy”, while all the laymen in Canon 7 are “anathematized”.
To summarize, if I am reading the above Canons correctly:
The various punishments for the clergy are:
“they shall absolutely forfeit their office”
“deposed”
“removed from his bishopric”
“stricken from the clergy”
The punishments for the laity are that they are:
“excommunicated”
“anathematized”
The questions seem to become, are the punishments for the clergy the same although they are expressed in different words? If so, it would seem logical that the same should follow for the punishments for the laity.
