Orthodox Mariology is every bit comparable if not superior to western. That doesn't mean the East necessarily believes what allegedly happened at Fatima in 1917 any more than the "dancing dun" supposedly 'witnessed" by 70,000 people.
Russia does not need evangelization or consecration. Russia has been consecrated when it became Christian.
She said she's heard that the big issues are less theological and more about Church structure, including that the Jesuits answer only to the pope. Any thoughts?
It is very much theological. With all due respect, I am wondering how well theologically informed is your friend. The issues are fundamentally dogmatic. They cut right into the latter-day Catholic dogmas of Immaculate Conception and papal infallibility, as well as older ones, such as the question of "created" grace, purgatory, and the original sin, just to mention a few. There are also deep ecclesial issues, such as the nature (not the question) of papal primacy, etc.
Some of these issues can be a matter of semantics (i.e. the purgatory) and possibly resolved rather quickly; others go much deeper than that and will most likely go on way past our lifetimes, if they go at all.
dancing dun = dancing sun
I agree that this is not going to be an overnight achievement. Honestly, it's going to be a multi-generational effort, IMO. But, that the condition of the world has forced us to start talking is not a minor thing. One thing that is nice is that one the ground we are talking amongst ourselves. My friend and I exchange stories and experiences all the time. I was on my way to Mass on the Solemnity of the Immaculate Conception and she asked what feast and I said, this is one of the bones of contention. At least there's a dialog. oss with ICXC every day.
