So are you saying that the power of binding and loosing ultimately boils down to absolutely nothing? If the power itself is ineffective when sinners are interiorly impenitent in confession
This is not some sort of esoteric Orthodox teaching. For the Latin West teaches that if one does not at least have attrition (imperfect contrition), the Sacrament of Penance will be invalid. The power of the keys cannot override certain preconditions on the part of the recipient of the sacrament.
and the power itself is ineffective when excommunications are invalid
Again, this is taught in the West too. If an excommunication is invalid (for reasons like the one who performed it did not properly have jurisdiction, his motives were incorrect, or he used improper form), then no excommunication occurred at all, so no binding ever happened. In the case of one unjustly (but validly) excommunicated, Pope Innocent III teaches, according to the Catholic Encyclopedia, that one excommunicated unjustly by the Church remains free in the sight of God, only being bound in the eyes of the Church, because God’s judgment is based upon the truth, while the judgment of the Church is necessarily based on an incomplete amount of information.
then what good is the power?
It is for the salvation of the flock. You almost seem as if you wish for the power to bind and loose to be an absolute, but this proposition would be manifestly false, for even in Western theology there are limitations upon the power to bind and loose due to the possibility that the Church may err on matters of discipline. One unjustly condemned by the Church will not be condemned in heaven by God, and one absolved without contrition will remain bound by his sins in the sight of God in heaven.
We are back in the protestant understanding that all that matters is the heart and God, two invisible things. This makes everyone justifiable.
No, it does not. It simply recognizes that, while the Church is the normative means of salvation, it is possible for God in cases when the Church errs in its application of discipline to judge one to be free who has been declared bound by the Church and vice-versa. If that is “protestant” then you must shove the entire Apostolic East and West into the category of “protestant”.
Was any authority conferred upon Peter when he was given the keys of the kingdom of heaven?
The authority to bind and loose.
And if anything authority was conferred, what was that authority?
It is the power of the sword, to cut some off from the flock, and also the power of loosing, which is the power to absolve those who have committed grievous sins and who return in contrition.
If it is just an “aid” to the already sufficient elements of a repentant heart and confused bishop, then it really is not authority whatsoever.
I did not say it is merely an aid. It is true authority insofar as it is exercised justly and with prudence, and being true authority from God, it is the normative fashion that those under the jurisdiction of the Church are able to work out their salvation with fear and trembling. But the Church may err in its application of discipline, and for this reason, God is not entirely beholden to a decision of the Church, and He may therefore circumvent the normative channels of grace as He sees fit.
Lastly, you need to read Joseph Ratzinger “Called to Communion”
I do not “need” to read his book, though his book is fascinating, I’m sure. Please refrain from presuming to know what I “need.” That is for my own confessor to determine.
on this whole popular orthodox understanding of the fullness of the Church being the presence of Christ, bodily, in the local eucharistic assembly. This sort of thinking is extremely reductionistic and anti-apostolic. You see because the office of the apostles was to all nations, and bishops as successors must be careful to make sure that his local diocese is interconnected with the breadth of the whole of which the office of the apostle pertains. We cannot have several autonomous bishops having the church for themselves here or there, and forget about being in communion with the rest in any active functional way.
Where did I ever say that? The East recognizes the importance of intercommunion, for the Church is in the image of the Trinity, and just as in the Trinity the divine nature subsists fully in each Hypostasis without division, so too the Church Catholic subsists fully (as opposed to partially) in each local church without division. Severing communion unjustly (that is to say, severing communion with others without the cause of them being heretics, schismatics or unlawful congregations, or without some other justifiable grievance) is a sin against the unity of the Church, damaging the Catholicity of the Church which does so. That being said, because of the substantial equality of bishops by reason of their equal inheritance of the Church Catholic, the question of “which jurisdiction do I join” is an iteration of the fallacy of exhaustive hypotheses. While overlapping jurisdictions in the new world are a problem, in the end to join the Russians or the Serbians is no different from joining the Greeks or the Georgians, as they do not differ on matters of faith (though they may differ on matters of theologoumena, just as in the West, bishops may differ on certain matters of theology without either being considered heretical).
