Dear brother in Christ Cavaradossi,
Nice theory, but falls flat on its face, given the fact that Western Christendom (apparently not knowing the theological nuances of the debate according to the Catholic Encyclopedia) refused to condemn the Three Chapters. It is useless for you to claim that the Fathers of the Fifth Ecum were willing to maintain communion with the Apostolic See when all the clergy in that See were on the side of Vigilius. It seems this claim that the Pope was struck from the diptychs must have been an interpolation of someone who did not understand the basic ecclesiology of the Church. You have not yet answered the original question.
How do you maintain communion with a See while simultaneously anathemizing its orthodox bishop? Try again.
What statements am I taking out of context? Please be specific.
Where does the Final Sentence of the Fifth Council indicate that Pope Vigilius was struck from the diptychs?
Please respond. You are depending completely on an excerpt of text that is not contained in the Final Sentence, an excerpt which likewise is not consistently contained in all the sources (i.e., the Emperor’s request that Pope Vigilius’ name be struck from the diptychs). Aside from that debatable excerpt, there is no indication anywhere else in the Council’s Acts that Pope Vigilius was actually anathematized or struck from the diptychs.
To be more precise, he withdrew his assent to the
holding of the Council
under the terms of the Emperor, since the Council would not be representative of all of Christendom.
Yes, he refused to participate as a protest to the Emperor’s heavy-handed tactics which did not give equal representation to Western bishops. But that does not mean that when the ball got rolling, he did not intend to be part of the conciliar proceedings. After all, the council still needed his confirmation.

In fact, the Pope gave his own judgment (the first Constitutum) in a collegial manner.
Pope Vigilius’ Constitutum was promulgated before the Final Sentence. It followed very closely the results of the Council of Chalcedon. The only thing different from Chalcedon was the theological condemnation of Theodore of Mopsuestia’s doctrines, information no doubt obtained from the proceedings of the Fifth Council (proof positive that he was working with the Council Fathers, contrary to your claim). It was not until almost three weeks later that the Fathers of the Fifth Ecum promulgated its Final Sentence which gave a detailed analysis of the the doctrinal issues as well as their rationale for condemning persons who died at peace with the Church.
There was no difference between the Faith held by Pope Vigilius and that of the Fifth Ecum, so they had no basis upon which to condemn him. The only real issue was the condemnation of persons who died at peace with the Church. The Final Sentence evinces that this was a keen issue at the Council, probably brought about by Pope Vigilius’ own first Constitutum. The Fathers of the Fifth Ecum knew that the issues raised by the first Constitutum were legitimate, so they had to defend their position on the condemnation of the persons by appealing to prior sources.
You also have to remember that Pope Vigilius did not understand Greek. In his final Constitutum, he plainly admits that he was not aware of all the facts, and only after becoming aware of everything did he confirm the Council’s Sentence.
There is no basis to believe the claim that Pope Vigilius was anathematized by the Fifth Council. What we have is a case of the body
working with their recognized head until consensus was reached.
Blessings,
Marduk
