Generally these threads devolve pretty fast from the intended OP. God willing, I’d like to slow down that process as much as possible.
I would say, personally, that there is a completely different mindset at play in both churches. In Orthodoxy, asceticism (fasting, prayer rule, spiritually etc) is much more emphasized than in Western confessions (Orthodox tend to lump Catholicism and Protestantism together because they are more alike than different). Ecclesiology is also very different, as is our idea on ‘doctrinal development’ (which we reject).
The two issues you have listed are major, but ultimately, I believe there are completely two different mindsets in both groups. My opinion, and the opinion of most of the clergy and laity I have met when discussing the issue say that Rome’s mindset would have to return to its Orthodox roots. We must have the same mindset and beliefs if we are to resume communion with one another. At present, we don’t have that.
In Christ,
Andrew
