No, but it does matter that we Protestants be allowed to think it -and, yes, say it.
By the way, I do not expect the Pope to think otherwise. If he did he should become a Protestant like me. I am also delighted he says it - that does come, after all, under his job description.
And I, for one, will not shrink from expiating the contrary.
You might want to proofread better (or check your dictionary!) -- I think you're saying something you didn't mean to! ;-)
