Forward to today.
As far as I know the EO does not have a unity among the 5 Churches. I don't seem to see a unit of one teaching.
Per the purpose of Jesus making Peter His steward. Of which, even in council, deferred to him.
As far as Honorius goes.
Honorius replied by referring to the
Council of Chalcedon’s
confession of faith (451), which held that Christ’s
natures were indivisible and which he
interpreted as meaning a single will in Christ.
Scholars believe that it is debatable whether he was a heretic. They hold that he seems to have misunderstood the point at issue, noting that his language is partially vague.
Monothelite, any of the 7th-century Christians who, while otherwise orthodox, maintained that Christ had only one will. The Monothelites were attempting to resolve the question of the unity of Christ’s person on the basis of the firmly established doctrine of the two natures, divine and human, in the person of Christ.
The controversy originated in the attempts by the
Byzantine emperor
Heraclius to win back for the church and empire the excommunicated and persecuted
Monophysites of Egypt and Syria. In Armenia in 622, Heraclius first suggested to the head of the Severian Monophysites that the divine and human natures in Christ, while quite distinct in his one person, had but one will (
thelēma) and one operation (
energeia).
Sergius, patriarch of Constantinople, was a strong upholder of the doctrine and was the emperor’s adviser on the question. In 638 Heraclius issued the
Ekthesis (“Statement of Faith”), which formulated the position. This led to such intense controversy that Heraclius’
successor,
Constans II, issued an edict in 648 forbidding all discussion of the question. This secured silence, despite the protest of the Western church at the Lateran Council of 649.
It was preceded in the same year by a synod under Pope
Agatho at
Rome. According to Agatho, the will is a property of the nature, so that, as there are two natures, there are two wills;
but the human will determines itself ever conformably to the divine and almighty will. The third
Council of Constantinople condemned Monothelitism and asserted two wills and two operations in the person of Christ.
Third Council of Constantinople | Description & Significance
Essentially Pope Leo was upset at Honorius, and it is said he was most upset he refused to teach on the matter.
Because he was vague, it remained open to interpretation of which Honorius dropped the ball and did a disservice to Peter's chair.
It was unsettling and upsetting to ALL that he did not teach or correct while on Peter's chair.
SO why is that so upsetting to all Churches and why did they finally find comfort in Rome's Pope Agatho to make the final conclusion??
Reminder: It was a council who created the problem/heresy.
