No, it is not.
From: http://www.newadvent.org/cathen/05678a.htm (Catholic Encyclopedia) --
Excommunication (Latin ex, out of, and communio or communicatio, communion — exclusion from the communion [They're not talking about the Eucharist here]), the principal and severest censure, is a medicinal, spiritual penalty that deprives the guilty Christian of all participation in the common blessings of ecclesiastical society.
Notice the wording of the final underlined portion. That goes far beyond the Eucharist. Sibelius is forbidden to receive the Eucharist, not "all participation".
I think this would be a distinction without a difference. I’m really not sure what else her bishop wrote - other than Holy Eucharist.
We’re talking about sacraments and liturgical here, not ‘all participation’ as in going to mass.
You can’t remove a baptism, so I’m not sure what you’re going for here.
Also, if you’re not Catholic, what is your church’s policy regarding politicians who support abortion?
