Only in your confession.
In the One Holy Catholic and Apostolic Church, unlike your confession, we don't believe that any man has the authority to condemn anyone to hell. I'm surprised to learn that your bishops seem to think they have such authority, and even more surprised that you believe them. And unlike your bishops, ours do not make such offerings to Satan.
In the One Holy Catholic and Apostolic Church, to pronounce someone "anathema" means to cut them off from the Church and hand them over to the judgement of God.
There is proof to the contrary.
The Russian Orthodox Church a couple years ago renewed an anathema on the Hetman Ivan Mazepa, for cooperating with the Swedes against the Russian Tsar. What sense there is in that, I do not know. There are plenty of Orthodox anathemas. The Greek Church had anathemised Nikos Kazantzakis and Constantine Kavafis? What for? For promoting Orthodoxy outside of Greece by way of literature. These anathemas were in the previous century.
Excommunication is officially damnation. Anathema is excommunication, the excommunicated, if they do not repent are damned.
That formula could be an invention of the author, it has no source. I truly wonder what is the source of that material. The best sources of Papal statements, as we all know, are Calvinist and Lutheran apologetic tracts. The Protestants seem to know the Pope than most Christians.
