2) My understanding is that the Orthodox church considers itself to be infallible as a whole. No offense intended, but this comes across to me as sounding rather arrogant. Although the Holy Spirit is present within the church and is understood as the Body of Christ, this doesn't place the church on the level of God Himself. It seems to me that only God Himself is truly infallible. Again, can you provide further explanation of the Orthodox viewpoint here?
Here is someone who expresses something of the Orthodox understanding more eloquently than I am able, Fr Georges Florovskyhttp://www.plasticsusa.com/ortho/Florovski.htm
"....the conviction of the Orthodox Church that the "guardian" of tradition and piety is the whole people, i.e. the Body of Christ, in no wise lessens or limits the power of teaching given to the hierarchy. It only means that the power of teaching given to the hierarchy is one of the functions of the catholic completeness of the Church; it is the power of testifying, of expressing and speaking the faith and the experience of the Church, which have been preserved in the whole body.
The teaching of the hierarchy is, as it were, the mouthpiece of the Church. De omnium fidelium ore pendeamus, quia in omnem fidelem Spiritus Dei Spirat. [We depend upon the word of all the faithful, because the Spirit of God breathes in each of the faithful, St. Paulin. Nolan, epist. 23, 25, M.L. 61. col. 281]. Only to the hierarchy has it been given to teach "with authority."
The hierarchs have received this power to teach, not from the church-people but from the High Priest, Jesus Christ, in the Sacrament of Orders. But this teaching finds its limits in the expression of the whole Church. The Church is called to witness to this experience, which is an inexhaustible experience, a spiritual vision. A bishop of the Church, episcopus in ecclesia, must be a teacher. Only the bishop has received full power and authority to speak in the name of his flock. The latter receives the right of speaking through the bishop. But to do so the bishop must embrace his Church within himself; he must make manifest its experience and its faith. He must speak not from himself, but in the name of the Church, ex consensu ecclesiae. This is just the contrary of the Vatican formula: ex sese, non autem ex consensu ecclesiae. [From himself, not from the consensus of the Church].
It is not from his flock that the bishop receives full power to teach, but from Christ through the Apostolic Succession. But full power has been given to him to bear witness to the catholic experience of the body of the Church. He is limited by this experience, and therefore in questions of faith the people must judge concerning his teaching. The duty of obedience ceases when the bishop deviates from the catholic norm, and the people have the right to accuse and even to depose him."
