So this relates to "Orthodox-Catholic Discussion" ... how?
Oh boy, duck.....we're going down the history hole soon....and not a pretty one either.
No, I read the Orthodox Wiki article http://orthodoxwiki.org/Maxim_Sandovich
It was not very long before the Austrian militia discovered his Orthodox pastoral and missionary service as he was denounced by a Ukrainian teacher by the name of Leos, in 1912. Immediately the Austrian gendarmes put Fr. Maxim in chains and sent him to prison in Lvov. There he was held for two years without a trial or inquest while being abused horribly and living in equally bad conditions. Then as World War I was to begin he was released for lack of evidence.
Note it says it was the "Austrian militia" that arrested him. If you're going to tell me that Austria was actively persecuting the Orthodox, in the name of the Roman Catholic Church, at the beginning of World War I, I may need some documentation.
Also, sorry, but what is the point of this? That in the past, Catholics have persecuted Orthodox? Yes, it's true. And in the past Orthodox have persecuted Catholics. In fact, pretty much every Christian group has persecuted other Christian group at one time or another. The question is, how do we, today, keep from persecuting our fellow Christians, today?
