Oh, Robb...where to begin....
I don't know much about the Russian Orthodox people, but, let me tell you a few things about us Ukrainian Orthodox people.
Ukrainians are extremely faithful. (Not including those who have been spoiled by the Soviet regime...God willing the next generation will revert back to the ways of the faithful.)
We do not like change. Not one iota.
We frown on any new/modern innovations when it comes to the Church.
We follow all the Traditions and traditions (and we have many) handed down to us through the years.
As for being less legalistic....you will only find that with folks who have intermarried with non-Orthodox, or who work and live amongst non-Orthodox and therefore, are influenced by their environment. These few will not see the benefit in fasting, will not attend services, etc.
However, these are simply individuals, and not the Church.
The Ukrainian Orthodox Church stands strong. She, her hierarchs, clergy and faithful support and defend all the canons of the True Church.
Robb, while I have my reservations as to various motives of the Moscow Patriarchate, in all honesty I do not think there is a "difference" between Ukrainian Orthodoxy and Russian Orthodoxy. I believe we both hold true to the laws handed down.
I would have no qualms about attending, confessing or receiving the Eucharist in a Russian Orthodox Church.
Now, if only Moscow would keep their eyes on, and hands strictly in Russian territory, and out of other countries...but, that's for a different thread.
