“However, when Miravalle advocates for the putative dogma, he makes clear that Mary co—redemptive role is akin, albeit unique, to the redemptive suffering of all faithful, and is therefore doing nothing to orthodox christology:”
If the Roman Church wants to make heretics out of 350,000,000 Orthodox Christians there isn’t much we can do about it. But I think every Roman Catholic, whether laity, clergy or hierarch, should understand that this “dogma” will guarantee that there will likely never be any reunion, indeed that the promulgation will be an example, in Orthodox eyes, of the the sort of “unorthodox” ecclesiology and uncontrolled theology which even today threatens to contaminate Eastern Christianity on account of its dialogs with Rome. Finally, those who advocate for this dangerous innovation must accept that it will frankly bring joy to the large majority of Orthodox as they will see it as the final nail in the coffin of a sort of ecumenism with which they profoundly disagree. I will be one of those Orthodox.
Like I said, I don't think she does, but neither is noticing the redemptive role of Mary -- to whom the Orthodox, after all, pray "Theotokos, save us", -- heretical.
