Anthony,
Did any of the councils themselves believe this?
Council of Ephesus:
“Philip the presbyter and legate of the Apostolic See said: There
is no doubt, and in fact it has been known in all ages, that the holy
and most blessed Peter, prince and head of the Apostles, pillar of the
faith, and foundation of the Catholic Church, received the keys of
the kingdom from our Lord Jesus Christ, the Saviour and Redeemer of
the human race, and that to him was given the power of loosing and
binding sins: who down even to to-day and forever both lives and
judges in his successors.” Council of Ephesus, Session III (A.D. 431).
Council of Chalcedon,responding to Pope Leo’s letter regarding the two natures
of Christ:
“This is the faith of the fathers! This is the faith of the Apostles! So we all
believe! thus the orthodox believe! Anathema to him who does not thus believe!
Peter has spoken thus through Leo! . . . This is the true faith!’” (Acts of the
Council, session 2 [A.D. 451]).
“Wherefore the most holy and blessed Leo, archbishop of the great and elder
Rome, through us, and through this present most holy synod together with the
thrice-blessed and all-glorious Peter the Apostle, who is the Rock and
foundation of the Catholic Church, and the foundation of the orthodox faith,
hath stripped him (Dioscorus, Bishop of Alexandria) of his episcopate, and hath
alienated from him all hieratic worthiness.” – Acts of Chalcedon, Session 3
“You are set as an interpreter to all of the voice of blessed Peter, and to all
you impart the blessings of that Faith.” – Chalcedon to Pope Leo, Ep 98
“For if where two or three are gathered together in His name He has said that
there He is in the midst of them, must He not have been much more particularly
present with 520 priests, who preferred the spread of knowledge concerning Him
…Of whom you were Chief, as Head to the members, showing your good will.” –
Chalcedon to Pope Leo (Repletum est Gaudio), November 451
“Besides all this, he (Dioscorus) extended his fury even against him who had
been charged with the custody of the vine by the Savior. We refer to Your
Holiness.” – Chalcedon to Pope Leo, Ep 98
“Knowing that every success of the children rebounds to the parents, we
therefore beg you to honor our decision by your assent, and as we have yielded
agreement to the Head in noble things, so may the Head also fulfill what is
fitting for the children.” – Chalcedon to Pope Leo, Ep 98
“Macedonius declared, when desired by the Emperor Anastasius to condemn the
Council of Chalcedon, that ‘such a step without an Ecumenical Synod presided
over by the Pope of Rome is impossible.’” (Macedonius, Migne PG 108:360a
[Theophan Chronogr, pages 234-346])
“Without whom (the Romans presiding in the seventh Council) a doctrine brought
forward in the Church could not, even though confirmed by canonical decrees and
by ecclesiastical usage, ever obtain full approval or currency. For it is they
(the Popes of Rome) who have had assigned to them the rule in sacred things, and
who have received into their hands the dignity of Headship among the Apostles.”
(St. Nicephorus, Niceph Cpl pro s imag c 25)
If it’s the case, why did the sixth ecumenical council condemn Pope
Honorius for officially teaching monothelitism?
The council did not condemn him for that - he did not teach the heresy - it condemned him for allowing the heresy to spread by remaining silent about it.
