Who is "His Eminence"? Metropolitan Hilarion or Cardinal Parolin? From the context (pace the headline of this thread), I suspect the former. However, the ambiguity in the article may be deliberate. I hope Cardinal Parolin is up to dealing with Moscow, but I do not feel sanguine about it.
I had forgotten that Metropolitan Hilarion uses the title "His Eminence". It may well have been he who made the statement about the UGCC, but --as you pointed out--the article is ambiguous as to which "His Eminence" said it.
I've changed the title of this thread in light of this.
